Kev pabcuam lub neej ntawm platinum RTDs feem ntau cuam tshuam los ntawm rau qhov tseem ceeb. Thawj yog siab - kub dhau, uas tshaj qhov ntsuas kub ntau thiab ua kom cov laus thiab ya raws ntawm platinum sensing caij. Qhov thib ob yog qhov nruab nrab corrosion, qhov twg cov kua qaub, alkali, roj thiab tshuaj lom neeg ua rau lub plhaub ntim thiab cov qauv sab hauv, ua rau lub rwb thaiv tsev tsis ua haujlwm thiab kev ua haujlwm tsis zoo. Thib peb, muaj zog txhua yam kev co thiab kev cuam tshuam yuav ua rau cov hlau lead hauv tawg, vuam qhov chaw loosening thiab cov qauv kev ntxhov siab puas tsuaj. Plaub, xoob xaim thiab kev sib cuag tsis zoo ua rau muaj kev tiv thaiv kev tiv thaiv thiab ua rau muaj teeb meem hloov pauv lossis txawm tias qhib Circuit Court. Thib tsib, noo noo thiab dej ingress rhuav tshem cov txheej txheem rwb thaiv tsev sab hauv, ua rau muaj kev tiv thaiv drift thiab luv luv Circuit Court. Thib rau, kev tsav tsheb ntau dhau yuav ua rau tus kheej - cua sov burnout, mus tas li ua rau cov nti nkag mus.
Txhawm rau ua kom lub neej ua haujlwm siab tshaj plaws ntawm platinum RTDs, kev tiv thaiv kev tiv thaiv thiab kev ua haujlwm tau zoo yog qhov tseem ceeb. Ua ntej, xaiv corrosion-cov ntaub ntawv ntim cov khoom tiv thaiv thiab cov qauv raws li nyob rau ntawm - qhov chaw nruab nrab, thiab nruab siab - lub zog tiv thaiv cov raj kom cais cov sensor los ntawm cov xov xwm hnyav. Qhov thib ob, nruj me ntsis txwv tsis pub siv tshaj qhov ntsuas kub ntau yam kom tsis txhob muaj kev puas tsuaj rau lub platinum. Thib peb, tswj cov tsav tsheb tam sim no tsawg dua lossis sib npaug li 1mA txhawm rau tshem tawm tus kheej - cua sov tsis raug thiab qhov phom sij kub hnyiab. Plaub, txais yuav cov qauv tsis muaj dej tsis zoo thiab tsis muaj plua plav sealing, thiab siv cov kev sib khi txhim khu kev qha thiab cov dej noo- cov ntaub ntawv pov thawj rau qhov chaw sab nraum zoov thiab ntub dej. Thib tsib, ntxiv dag zog rau kev txhim kho ruaj khov kom tiv thaiv kev co, thiab xyuas kom ruaj khov crimping ntawm cov hlua txuas kom tsis txhob xoob. Thib rau, ua cov calibration tsis tu ncua thiab kev ntsuas kev ua tau zoo los taug qab kev tiv thaiv drift thiab tshem tawm qhov ua yuam kev ua ntej. Tsis tas li ntawd, khaws lub sensor kom deb ntawm qhov muaj zog electromagnetic cuam tshuam thiab muaj zog corrosive thaj chaw kom ntau li ntau tau.
Platinum RTDs tau teeb tsa thiab siv raws li cov lus qhia tshwj xeeb qhia tau hais tias tsis tshua muaj kev tiv thaiv me me, feem ntau tsawg dua 0.01℃hauv ib xyoos, tswj kev ua haujlwm ntev - lub sijhawm ruaj khov. Piv nrog rau qis -kawg sensors uas yuav tsum tau hloov tas li, platinum RTDs muaj cov nqi pib dua tab sis txo qis tag nrho lub neej- mus txog tus nqi. Nyob rau hauv niaj hnub kev lag luam automation, lub zog tshiab, petrochemical thiab tshuaj lag luam, lub sij hawm ntev - kev ntseeg siab ntawm platinum RTDs zoo heev txo lub sij hawm poob, kev tu cov hauj lwm thiab cov nqi hloov. Los ntawm kev siv cov kev tiv thaiv kev tshawb fawb thiab kev tswj xyuas, cov neeg siv tuaj yeem tso tawm qhov kev ua tau zoo ntawm platinum RTDs thiab ua tiav qhov ntsuas kub ruaj khov, ua haujlwm tau zoo thiab kev lag luam rau lub sijhawm ntev.
