Nyob rau hauv lub cheeb tsam ntawm kev ntsuas kub, thermal kuj, feem ntau hu ua RTD (Resistance Temperature Detector), yog txaus siab rau nws zoo kawg li qhov tseeb thiab stability nyob rau hauv qhov qis mus rau nruab nrab kub ntau yam. Thaum muaj ntau txoj hauv kev los saib xyuas cov cua sov, qhov kev ntseeg siab ntawm kev ua haujlwm -raws li qhov system tsis sib xws rau precision engineering. Lub thermal tsis kam sensor ua haujlwm ntawm lub hauv paus ntsiab lus tias qhov hluav taws xob tsis kam ntawm cov hlau- feem ntau platinum, zoo li hauv WZ series- nce kev kwv yees li qhov kub nce. Cov yam ntxwv no yog hu ua kub coefficient ntawm kev tiv thaiv. Txoj kev sib raug zoo no tso cai rau kev nyeem ntawv ntau dua li cov uas tau muab los ntawm cov qauv thermocouples, ua rau cov thermal kuj yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas ib feem ntawm cov℃teeb meem, xws li hauv kev ua tshuaj zoo, cov khoom noj khoom haus, thiab cov khoom tiv thaiv ib puag ncig. Hauv kev lag luam dav dav, cov sensors no tau muab faib los ntawm lawv cov khoom siv thiab cov nqi tiv thaiv ntawm xoom degrees Celsius, nrog rau PT100 thiab PT1000 yog cov qauv siv ntau tshaj. WZ series tseem yog ib qho tseem ceeb hauv kev ua lag luam vim nws muaj ntau yam thiab ua raws li cov qauv kev ntsuas thoob ntiaj teb, kom ntseeg tau tias cov khoom tuaj yeem hloov pauv lossis koom ua ke rau hauv lub ntiaj teb no yam tsis muaj teeb meem kev sib raug zoo.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm lub ntsuas hluav taws xob tiv thaiv yog nws lub sijhawm ntev - ruaj khov; siab -RTDs zoo tuaj yeem tswj hwm lawv qhov ntsuas tau ntau xyoo yam tsis muaj kev cuam tshuam loj, uas txo qhov kev xav tau ntawm kev saib xyuas thiab rov kho dua. Qhov no yog qhov tseem ceeb tshaj plaws rau cov chaw ua haujlwm 24/7 uas lub sijhawm poob rau kev hloov pauv hloov pauv tuaj yeem ua rau poob nyiaj txiag loj. Ntawm peb lub Hoobkas, peb siv cov cuab yeej ntsuas kub tsis siv neeg thiab tag nrho -bridge LCR testers los xyuas qhov tseeb ntawm txhua WZ series resistor. Txhua chav tsev yuav tsum dhau los ntawm cov chaw soj ntsuam nruj nruj kom ntseeg tau tias cov hlau hauv platinum yog qhov mob zoo kawg nkaus thiab rwb thaiv tsev. Tsis tas li ntawd, cov thermal resistance sensors tsis tshua muaj suab nrov rau hluav taws xob, uas yog qhov zoo tshaj plaws hauv kev lag luam ib puag ncig uas muaj cov motors thiab keyboards. Tsis zoo li cov thermocouples, uas tsim cov teeb liab millivolt me me uas tuaj yeem cuam tshuam tau yooj yim los ntawm electromagnetic cuam tshuam, qhov kev hloov pauv hauv RTD yog qhov muaj zog dua. Qhov no ua rau RTD zoo tagnrho rau siv nyob ze rau cov tshuab hnyav lossis siab - cov kab hluav taws xob uas qhov teeb meem kev ncaj ncees yog qhov nyuaj rau cov engineers thiab cov kws tshaj lij.
Kev siv tswv yim thiab kev teeb tsa ntawm cov sensors no yuav tsum muaj kev nkag siab tob txog cov hluav taws xob ib puag ncig. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tau xav txog "cov hlau lead-tiv thaiv" thaum txhim kho cov sensors, uas yog vim li cas 3-wire thiab 4-xaim teeb tsa feem ntau siv los them rau qhov kev tiv thaiv ntawm cov cables nyob rau hauv qhov ntev. Nyob rau hauv ib qho yooj yim 2-xaim teeb, qhov kev tiv thaiv ntawm kev sib txuas cov hlau lead yog ntxiv rau kev nyeem ntawv sensor, uas tuaj yeem ua rau muaj qhov kub tsis zoo vim qhov kev ncua deb ntawm lub sensor thiab tus maub los nce. Los ntawm kev siv 3-xaim teeb tsa, tus choj ntsuas tuaj yeem tshem tawm cov hlau lead tsis kam, muab qhov tseeb ntau dua. Rau cov nroj tsuag tshuaj uas cuam tshuam nrog cov tshuaj corrosive, peb muab tshwj xeeb los tiv thaiv corrosion thermal resistance probes uas muaj patented tiv thaiv txheej. Cov txheej txheem no, feem ntau yog tsim los ntawm tshwj xeeb fluoropolymers lossis stainless hlau alloys zoo li 316L, tiv thaiv cov ntsiab lus rhiab hauv lub cev los ntawm cov kua qaub hnyav, alkalis, thiab noo noo, ncua kev pab cuam lub neej ntawm cov khoom siv nyob rau hauv qhov xav tau tshaj plaws sab nraum zoov kev lag luam scenarios.
Thaum muab tso rau hauv lub ntsuas kub tswj qhov system, cov sensors muab lub teeb liab huv si, ruaj khov uas tso cai rau kev tswj PID nruj heev. Qhov sib npaug -Integral-Derivative (PID) maub los tso siab rau cov lus pom tseeb thiab ceev ceev kom tswj tau qhov kub thiab txias, thiab txhua qhov kev hloov pauv lossis suab nrov ntawm lub sensor tuaj yeem ua rau tag nrho lub cev oscillate lossis ua tsis tiav. Los ntawm kev xaiv lub siab -precision thermal resistance sensor, tshuaj lom neeg thiab cov chaw tsim khoom tuaj yeem ua kom lawv cov txheej txheem nyob rau hauv nruj kev nyab xeeb thiab zoo txwv, thaum kawg txhim kho qhov sib xws ntawm lawv cov zis thiab kev nyab xeeb ntawm lawv cov haujlwm. Raws li lub ntiaj teb kev tsim khoom txav mus rau Kev Lag Luam 4.0, lub luag haujlwm ntawm kev ua haujlwm siab - leakage thiab kev tiv thaiv kub tau dhau los ua qhov tseem ceeb rau kev tsim khoom ntse. Kev nrhiav cov sensors nrog kev ua haujlwm ruaj khov yog qhov tseem ceeb tshaj plaws rau cov tuam txhab engineering hauv Middle East, Europe, thiab Southeast Asia, vim lawv nrhiav kom tau raws li cov cai hauv tsev nruj thiab kev nyab xeeb. Los ntawm kev txhim kho txuas ntxiv hauv kev tsim thiab kev sib koom ua ke ntawm cov khoom siv thev naus laus zis, cov khoom siv thev naus laus zis niaj hnub ua haujlwm ua tus neeg saib xyuas ntsiag to, ua kom muaj txiaj ntsig ntawm ob qho tib si lub neej niaj hnub thiab hnyav{11}} lub luag haujlwm kev lag luam.
