Non possono chiaramente rilevare aria in altre parti del sistema. \u00c8 certamente una buona pratica utilizzare questi dispositivi principalmente su sistemi chiusi.<\/p>\n\n\n\n<p>Nei sistemi con serbatoi aperti, spesso vengono utilizzati dei deflettori per permettere all`aria di diffondersi naturalmente nell`atmosfera circostante. Quando si utilizza questo tipo di sistema, \u00e8 essenziale mantenere il livello del serbatoio sufficientemente alto in modo che i deflettori possano essere efficaci. Quando il fluido ritorna al serbatoio, assicurarsi anche che il flusso venga diffuso in modo che non si verifichi uno scarico improvviso e violento. Quest`ultimo pu\u00f2 infatti trascinare aria nel sistema, e certamente non aiuter\u00e0 a rimuovere aria eventualmente gi\u00e0 intrappolata. Cercare di mantenere bassa la portata del ritorno al serbatoio e scaricare il fluido verso la superficie dello stesso per favorire la fuoriuscita di aria.<\/p>\n\n\n\n<p>Per valutare la quantit\u00e0 di aria presente nel sistema, misurare il livello del fluido sia con serbatoio pressurizzato che non pressurizzato. Se il livello del fluido nel serbatoio \u00e8 pi\u00f9 basso quando \u00e8 pressurizzato, questo potrebbe essere un`indicazione della presenza di aria nel sistema e segnalare che potrebbe essere necessaria un`appropriata manutenzione.<\/p>\n<\/div><\/div><\/div>\n<\/details>\n\n\n\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-4f8f8e4 is-style-default\" data-block-id=\"4f8f8e4\"><style>.stk-4f8f8e4 {margin-top:0px !important;margin-right:0px !important;margin-bottom:0px !important;margin-left:0px !important;}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-bcd412a stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"bcd412a\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-bcd412a-container stk-hover-parent\"><div class=\"stk-block-content stk-inner-blocks stk-bcd412a-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-3bbab41\" data-block-id=\"3bbab41\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-7c7dafc\" id=\"che-effetto-ha-l-aria-su-un-sistema\" data-block-id=\"7c7dafc\"><h4 class=\"stk-block-heading__text\">Che effetto ha l`aria su un sistema?<\/h4><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-ddea33f\" data-block-id=\"ddea33f\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-ddea33f\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-ddea-33-f-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-ddea-33-f-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-0b0af4c stk-block-accordion__content\" data-v=\"4\" data-block-id=\"0b0af4c\"><style>.stk-0b0af4c {border-style:solid !important;border-color:#E6E6E6 !important;border-top-width:0px !important;border-right-width:1px !important;border-bottom-width:0px !important;border-left-width:1px !important;max-width:1440px !important;min-width:auto !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-0b0af4c-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-0b0af4c-inner-blocks\">\n<p>Un fluido areato pu\u00f2 causare diversi problemi di varia gravit\u00e0, che dovrebbero essere evitati, ove possibile, per mantenere&nbsp;&nbsp;al sicuro gli operatori e bassi i costi di manutenzione.

In presenza di alte concentrazioni di acqua, l`olio diventa torbido o opaco e si dovrebbe quindi prendere in considerazione se sostituirlo con uno nuovo.<\/p>\n\n\n\n<p>Per eliminare il rischio di guasti indotti dall`acqua, si pu\u00f2 prendere in considerazione la seguente lista di accorgimenti e best practices:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>corretta gestione e manipolazione dell`olio<\/li>\n\n\n\n<li>uso di sfiati o protezione dello spazio vuoto in testa al serbatoio<\/li>\n\n\n\n<li>lavaggio degli impianti e protezione degli stessi durante questa operazione<\/li>\n\n\n\n<li>grado di protezione IP delle apparecchiature montate sul sistema e la loro suscettibilit\u00e0 all`ingresso di umidit\u00e0<\/li>\n\n\n\n<li>formazione di condensa nell`area circostante<\/li>\n\n\n\n<li>tenute secondarie per applicazioni critiche<\/li>\n\n\n\n<li>conservare i fusti di olio al chiuso<\/li>\n\n\n\n<li>svuotamento e drenaggio periodico di sistemi particolarmente sensibili<\/li>\n\n\n\n<li>formazione accurata degli operatori<\/li>\n<\/ul>\n<\/div><\/div><\/div>\n<\/details>\n<\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-c47e2d7\" data-v=\"4\" role=\"tabpanel\" data-block-id=\"c47e2d7\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-c47e2d7-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-c47e2d7-inner-blocks\">\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-4739ac9 is-style-default\" data-block-id=\"4739ac9\"><style>.stk-4739ac9 {margin-top:0px !important;margin-right:0px !important;margin-bottom:0px !important;margin-left:0px !important;}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-debd395 stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"debd395\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-debd395-container stk-hover-parent\"><div class=\"stk-block-content stk-inner-blocks stk-debd395-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-2b148a4\" data-block-id=\"2b148a4\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-4a9d520\" id=\"com-e-possibile-limitare-la-contaminazione-di-solidi-che-entra-nel-sistema\" data-block-id=\"4a9d520\"><h4 class=\"stk-block-heading__text\">Com`\u00e8 possibile limitare la contaminazione di solidi che entra nel sistema?<\/h4><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-3ea55da\" data-block-id=\"3ea55da\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-3ea55da\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-3-ea-55-da-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-3-ea-55-da-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-ac00e8e stk-block-accordion__content\" data-v=\"4\" data-block-id=\"ac00e8e\"><style>.stk-ac00e8e {border-style:solid !important;border-color:#E6E6E6 !important;border-top-width:0px !important;border-right-width:1px !important;border-bottom-width:0px !important;border-left-width:1px !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-ac00e8e-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-ac00e8e-inner-blocks\">\n<p>E` essenziale utilizzare le varie best practices di pulizia del sistema.

Ci\u00f2 che si pu\u00f2 dire \u00e8 che la decisione di controllare la contaminazione si basa normalmente sulla sensibilit\u00e0 dei componenti all`interno del processo (ad es. servovalvole, attuatori). Esistono dati ampiamente pubblicizzati sui dati validati e consigliati per questo tipo di componenti. Si trovano anche all`interno dei nostri manuale.<\/p>\n\n\n\n<p>Una delle cose principali che viene trascurata nel settore \u00e8 l\u2019indice di pulizia che stiamo cercando di controllare e misurare. Questo \u00e8 importante da considerare, in quanto pu\u00f2 cambiare il modo in cui si sceglie di utilizzare i dati per ottenere un quadro pi\u00f9 realistico delle condizioni del sistema nel tempo. Di seguito \u00e8 riportato un diagramma che mostra le dimensioni tipiche delle particelle che filtriamo ogni giorno e che misuriamo con gli APC rispetto agli oggetti comuni. Mette nella giusta prospettiva la sfida affrontata nella progettazione di un sistema. Eliminare tutti i contaminanti al di sotto di una certa dimensione\/soglia \u00e8 estremamente difficile se si considerano tutte le possibili fonti di contaminazione che circondano il sistema. Occorre sempre fare attenzione a scegliere l`attrezzatura giusta e utilizzare metodi statistici adeguati quando si valutano i dati, si prendono decisioni e si agisce.<\/p>\n<\/div><\/div><\/div>\n<\/details>\n\n\n\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-44da76c is-style-default\" data-block-id=\"44da76c\"><style>.stk-44da76c {margin-top:0px !important;margin-right:0px !important;margin-bottom:0px !important;margin-left:0px !important;}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-277d582 stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"277d582\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-277d582-container stk-hover-parent\"><div class=\"stk-block-content stk-inner-blocks stk-277d582-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-570a3e9\" data-block-id=\"570a3e9\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-c1601d4\" id=\"quali-sono-i-tipi-di-contaminazione-predominanti-in-un-sistema-oleodinamico\" data-block-id=\"c1601d4\"><h4 class=\"stk-block-heading__text\">Quali sono i tipi di contaminazione predominanti in un sistema oleodinamico?<\/h4><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-838326e\" data-block-id=\"838326e\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-838326e\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-838326-e-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-838326-e-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-5936bfe stk-block-accordion__content\" data-v=\"4\" data-block-id=\"5936bfe\"><style>.stk-5936bfe {border-style:solid !important;border-color:#E6E6E6 !important;border-top-width:0px !important;border-right-width:1px !important;border-bottom-width:0px !important;border-left-width:1px !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-5936bfe-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-5936bfe-inner-blocks\">\n<p>Questo pu\u00f2 variare notevolmente, a seconda del tipo di sistema e di installazione, ma qui di seguito sono riportate alcune contaminazioni tipiche.

Poich\u00e9 \u00e8 fisicamente impossibile raggiungere il 100% di efficienza in un dato sistema, alcune particelle passeranno sempre attraverso la filtrazione.

Nel corso del tempo, e in reazione alle mutevoli condizioni dei fluidi come temperatura, pressione e decomposizione chimica, questi materiali possono diventare suscettibili alla corrosione e rilasciare contaminanti nel sistema.<\/p>\n\n\n\n<p>L`omogeneit\u00e0 gioca un ruolo significativo nella valutazione accurata della contaminazione in un sistema, in quanto una soluzione omogenea \u00e8 uniforme nella sua composizione e le particelle sono distribuite uniformemente al suo interno.<\/p>\n\n\n\n<p>\u00c8 giusto concludere affermando che la maggior parte dei sistemi del mondo

l`altro.<\/p>\n\n\n\n<p>Fattori quali, ma non solo, la viscosit\u00e0, la temperatura, la conducibilit\u00e0 elettrica, la tensione superficiale possono contribuire negativamente alla qualit\u00e0

L`efficienza di un filtro pu\u00f2 essere fortemente influenzata da variazioni di viscosit\u00e0, omogeneit\u00e0 del fluido, conducibilit\u00e0 elettrica, per citarne solo alcune. Attualmente c`\u00e8 una richiesta da parte dell`industria di pi\u00f9 standard e normative relative ai metodi di prova. Negli ultimi anni, a causa della vasta gamma di fluidi disponibili, alcuni gruppi hanno creato i propri standard per i metodi di prova.<\/p>\n\n\n\n<p>Quando si sceglie un filtro, \u00e8 importante capire qual \u00e8 il rapporto di filtrazione Beta assoluto, quindi capire quale dovrebbe essere la dimensione delle particelle pi\u00f9 grandi che circolano nel sistema. Unendo questo fattore con un APC \u00e8 possibile quantificare il numero di particelle di una determinata dimensione nel sistema e avviare il processo di controllo qualit\u00e0. Diversi filtri in serie spesso migliorano la pulizia di un sistema, cos\u00ec come il tempo di esposizione.<\/p>\n<\/div><\/div><\/div>\n<\/details>\n\n\n\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-6021b38 is-style-default\" data-block-id=\"6021b38\"><style>.stk-6021b38 {margin-top:0px !important;margin-right:0px !important;margin-bottom:0px !important;margin-left:0px !important;}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-ebf09c6 stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"ebf09c6\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-ebf09c6-container stk-hover-parent\"><div class=\"stk-block-content stk-inner-blocks stk-ebf09c6-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-facb070\" data-block-id=\"facb070\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-5e6f251\" id=\"quando-devono-essere-sostituiti-i-filtri\" data-block-id=\"5e6f251\"><h4 class=\"stk-block-heading__text\">Quando devono essere sostituiti i filtri?<\/h4><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-c039eb0\" data-block-id=\"c039eb0\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-c039eb0\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-c-039-eb-0-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-c-039-eb-0-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-48eff39 stk-block-accordion__content\" data-v=\"4\" data-block-id=\"48eff39\"><style>.stk-48eff39 {border-style:solid !important;border-color:#E6E6E6 !important;border-top-width:0px !important;border-right-width:1px !important;border-bottom-width:0px !important;border-left-width:1px !important;max-width:1440px !important;min-width:auto !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-48eff39-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-48eff39-inner-blocks\">\n<p>La logica imporrebbe di cambiare i filtri quando il livello di pulizia del sistema inizia ad aumentare al di sopra dei livelli utilizzabili.

Da un punto di vista pratico, a volte i sistemi non hanno punti di campionamento collegati ad essi, fattore che pu\u00f2 influire sulle decisioni relative alle modalit\u00e0 di analisi dei fluidi.<\/p>\n<\/div><\/div><\/div>\n<\/details>\n\n\n\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-aeb83a5 is-style-default\" data-block-id=\"aeb83a5\"><style>.stk-aeb83a5 {margin-top:0px !important;margin-right:0px !important;margin-bottom:0px !important;margin-left:0px !important;}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-5a67217 stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"5a67217\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-5a67217-container stk-hover-parent\"><div class=\"stk-block-content stk-inner-blocks stk-5a67217-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-4e7259d\" data-block-id=\"4e7259d\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-d8a51f0\" id=\"l-importanza-di-conteggi-dettagliati\" data-block-id=\"d8a51f0\"><h4 class=\"stk-block-heading__text\">L`importanza di conteggi dettagliati<\/h4><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-d7e4b2b\" data-block-id=\"d7e4b2b\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-d7e4b2b\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-d-7-e-4-b-2-b-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-d-7-e-4-b-2-b-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-2919b74 stk-block-accordion__content\" data-v=\"4\" data-block-id=\"2919b74\"><style>.stk-2919b74 {border-style:solid !important;border-color:#E6E6E6 !important;border-top-width:0px !important;border-right-width:1px !important;border-bottom-width:0px !important;border-left-width:1px !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-2919b74-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-2919b74-inner-blocks\">\n<p>L`uso e l`analisi esclusiva dei formati di reporting internazionali non fornisce un`immagine fedele del fatto che un sistema sia sotto controllo o fuori controllo.<\/p>\n\n\n\n<p>Anche se tutti i formati internazionali sono basati su un solido metodo di calcolo, sono tutti sensibili al cambiamento anche di un solo conteggio qualunque sia la concentrazione. Ad esempio, la norma ISO 14 indica che nel vostro sistema sono presenti tra le 80 e le 160 particelle di una determinata dimensione. Se la concentrazione nel sistema passa a 161, l`APC emetter\u00e0 un risultato di ISO 15.

Alcuni prodotti hanno funzioni secondarie come la capacit\u00e0 di misurare la temperatura e il contenuto di umidit\u00e0. Normalmente producono risultati in formati standard internazionali (AS4059E, ecc.) e il pi\u00f9 delle volte i dati dei dispositivi possono essere memorizzati e recuperati per l`analisi continua dello stato di un sistema. Attualmente sono suddivise in due categorie distinte, portatili (o off line) e in linea.<\/p>\n\n\n\n<p>I contatori automatici di particelle esistono dagli anni `60. Il principio su cui operano si \u00e8 mantenuto vicino al loro concetto originale, ma nel corso del tempo sono stati sviluppati utilizzando diversi metodi come la tecnologia delle lenti o la fonte luminosa. Storicamente, il conteggio delle particelle \u00e8 sempre stato fatto con un metodo abbastanza rigoroso ed esteso, come la microscopia ottica, che prevedeva il conteggio fisico della concentrazione di particelle. Con l`aumentare del tempo e della domanda di questo tipo di dati, \u00e8 stata necessaria una nuova tecnologia per rendere l`analisi pi\u00f9 pratica ed economica per l`utente. L`analisi automatizzata delle particelle \u00e8 stata quella vincente a livello di praticit\u00e0 ed economia.<\/p>\n<\/div><\/div><\/div>\n<\/details>\n<\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-4bfeb87\" data-v=\"4\" role=\"tabpanel\" data-block-id=\"4bfeb87\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-4bfeb87-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-4bfeb87-inner-blocks\">\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-6d4d1cd is-style-default\" data-block-id=\"6d4d1cd\"><style>.stk-6d4d1cd {margin-top:0px !important;margin-right:0px !important;margin-bottom:0px !important;margin-left:0px !important;}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-e660fc4 stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"e660fc4\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-e660fc4-container stk-hover-parent\"><div class=\"stk-block-content stk-inner-blocks stk-e660fc4-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-af9dbd6\" data-block-id=\"af9dbd6\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-3549609\" id=\"come-funzionano-i-sensori-di-umidita-nell-olio\" data-block-id=\"3549609\"><h4 class=\"stk-block-heading__text\">Come funzionano i sensori di umidit\u00e0 nell`olio?<\/h4><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-fa87574\" data-block-id=\"fa87574\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-fa87574\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-fa-87574-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-fa-87574-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-d22bd9c stk-block-accordion__content\" data-v=\"4\" data-block-id=\"d22bd9c\"><style>.stk-d22bd9c {border-style:solid !important;border-color:#E6E6E6 !important;border-top-width:0px !important;border-right-width:1px !important;border-bottom-width:0px !important;border-left-width:1px !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-d22bd9c-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-d22bd9c-inner-blocks\">\n<p>I sensori di umidit\u00e0, in RH% o ppm, funzionano tipicamente con un metodo capacitivo che utilizza un dielettrico inserito tra due piastre metalliche.

Il valore del dielettrico per il sensore polimerico \u00e8 di circa 3. La variazione del dielettrico rilevato, permette di arrivare ad una cifra percentuale.

Tuttavia, attraverso test e sviluppo, i sensori progettati per l`uso in aria possono essere adottati ed applicati. Si consiglia di applicare un adeguato pre-controllo quando si impostano i limiti di allarme per il contenuto di umidit\u00e0. Questo andr\u00e0 a beneficio sia del sensore che del sistema. Quando si analizza un sistema\/processo, meglio effettuare diverse letture dell`umidit\u00e0 e applicare metodi statistici validi per arrivare al calcolo della capacit\u00e0 del sistema.<\/p>\n<\/div><\/div><\/div>\n<\/details>\n\n\n\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-db415e9 is-style-default\" data-block-id=\"db415e9\"><style>.stk-db415e9 {margin-top:0px !important;margin-right:0px !important;margin-bottom:0px !important;margin-left:0px !important;}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-8a01de3 stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"8a01de3\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-8a01de3-container stk-hover-parent\"><div class=\"stk-block-content stk-inner-blocks stk-8a01de3-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-670c54a\" data-block-id=\"670c54a\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-72af754\" id=\"cos-e-l-umidita-relativa-rh\" data-block-id=\"72af754\"><h4 class=\"stk-block-heading__text\">Cos`\u00e8 l`umidit\u00e0 relativa (RH%)?<\/h4><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-9fe909a\" data-block-id=\"9fe909a\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-9fe909a\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-9-fe-909-a-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-9-fe-909-a-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-a11e554 stk-block-accordion__content\" data-v=\"4\" data-block-id=\"a11e554\"><style>.stk-a11e554 {border-style:solid !important;border-color:#E6E6E6 !important;border-top-width:0px !important;border-right-width:1px !important;border-bottom-width:0px !important;border-left-width:1px !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-a11e554-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-a11e554-inner-blocks\">\n<p>L`umidit\u00e0 relativa (RH%) descrive la quantit\u00e0 di vapore acqueo in un fluido oleodinamico. Quando il contenuto di vapore aumenta fino a condensare fuori dal fluido, si parla di &#8220;saturazione&#8221; o &#8220;acqua libera&#8221;. Mentre allo stato vapore, l`acqua \u00e8 disciolta e di meno importanza per il sistema. Una volta che si \u00e8 saturata, l`acqua \u00e8 presente come piccole goccioline d`acqua.<\/p>\n\n\n\n<p>Un sistema saturo dar\u00e0 una lettura RH del 99%\/100%. In generale, una lettura dell`RH dal 30% al 70% \u00e8 tipica dei sistemi oleodinamici. La variazione di lettura pi\u00f9 spesso \u00e8 legata alle variazioni della temperatura ambiente. Ci si aspetta, ad esempio, di vedere letture di UR pi\u00f9 elevate in inverno che nei mesi estivi. Non esiste una situazione di &#8220;troppo poca acqua&#8221; in un sistema oleodinamico. Mantenete sempre il livello di umidit\u00e0 il pi\u00f9 basso possibile e non permettete all`acqua libera di formarsi all\u2019interno dei vostri processi!<\/p>\n<\/div><\/div><\/div>\n<\/details>\n\n\n\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-2bb2040 is-style-default\" data-block-id=\"2bb2040\"><style>.stk-2bb2040 {margin-top:0px !important;margin-right:0px !important;margin-bottom:0px !important;margin-left:0px !important;}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-7c466fb stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"7c466fb\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-7c466fb-container stk-hover-parent\"><div class=\"stk-block-content stk-inner-blocks stk-7c466fb-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-817ee72\" data-block-id=\"817ee72\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-b19a827\" id=\"qual-e-la-differenza-tra-parti-per-milione-e-rh\" data-block-id=\"b19a827\"><h4 class=\"stk-block-heading__text\">Qual \u00e8 la differenza tra parti per milione e RH%?<\/h4><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-1af4cc6\" data-block-id=\"1af4cc6\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-1af4cc6\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-1-af-4-cc-6-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-1-af-4-cc-6-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-68bb058 stk-block-accordion__content\" data-v=\"4\" data-block-id=\"68bb058\"><style>.stk-68bb058 {border-style:solid !important;border-color:#E6E6E6 !important;border-top-width:0px !important;border-right-width:1px !important;border-bottom-width:0px !important;border-left-width:1px !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-68bb058-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-68bb058-inner-blocks\">\n<p>Se usati in modo responsabile e con il corretto approccio sul controllo della qualit\u00e0, sia ppm sia RH% sono ottimi modi per misurare il contenuto di umidit\u00e0 nei fluidi oleodinamici.

L`ingegnere installa un sensore di umidit\u00e0 in un sistema contenente lo stesso fluido, e imposta un limite di allarme di 640 ppm (80% RH). Il processo viene messo in moto e la lettura iniziale del sensore \u00e8 di 400 ppm (50% RH).

Ci\u00f2 che l`operatore non sa \u00e8 che il sistema \u00e8 ora in funzione al 95% di saturazione che \u00e8 pericolosamente vicino all`acqua libera esistente nel processo e al di sopra della soglia dell`80% impostata nell`allarme. Considerate che per la segnalazione dell`allarme, dovreste avere l`acqua libera nel sistema! Si tratta di un processo fuori controllo e l`unico modo per renderlo possibile sarebbe quello di convalidare il punto di saturazione dei campioni prelevati ad intervalli prestabiliti per tutta la durata del sistema.<\/p>\n\n\n\n<p>Se l`ingegnere avesse utilizzato RH% fin dall`inizio e dato l`esempio di cui sopra, l`allarme si sarebbe alzato quando il punto di saturazione del fluido si era ridotto a 625 ppm (100%). Il limite di allarme rimarrebbe a 80%RH, ma il valore ppm equivalente sarebbe ora

Se sono necessari risultati al punto di utilizzo, questa tendenza pu\u00f2 essere eseguita nell`ambito della messa in funzione dell`attrezzatura in modo da essere informati fin dal primo giorno.<\/p>\n<\/div><\/div><\/div>\n<\/details>\n\n\n\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-b5dd7e2 is-style-default\" data-block-id=\"b5dd7e2\"><style>.stk-b5dd7e2 {margin-top:0px !important;margin-right:0px !important;margin-bottom:0px !important;margin-left:0px !important;}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-8b687e4 stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"8b687e4\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-8b687e4-container stk-hover-parent\"><div class=\"stk-block-content stk-inner-blocks stk-8b687e4-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-55d34af\" data-block-id=\"55d34af\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-3e92e54\" id=\"come-ottenere-il-massimo-dai-dati\" data-block-id=\"3e92e54\"><h4 class=\"stk-block-heading__text\">Come ottenere il massimo dai dati?<\/h4><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-1e7f450\" data-block-id=\"1e7f450\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-1e7f450\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-1-e-7-f-450-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-1-e-7-f-450-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-0202ffc stk-block-accordion__content\" data-v=\"4\" data-block-id=\"0202ffc\"><style>.stk-0202ffc {border-style:solid !important;border-color:#E6E6E6 !important;border-top-width:0px !important;border-right-width:1px !important;border-bottom-width:0px !important;border-left-width:1px !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-0202ffc-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-0202ffc-inner-blocks\">\n<p>Normalmente le tabelle di controllo preliminare vengono utilizzate per monitorare le informazioni provenienti dai sistemi.
