Vim li cas thiaj ua thermouvles yuav tsum muaj calibrated? Ntev npaum li cas yog kev tshawb fawb txog kev tshawb fawb?

Ib qho ntsuas ntsuas yuav tsum yog ntsuas lossis ntsuas raws li cov kev ntsuas ntawm kev ntsuas hluav taws xob cuam tshuam lossis cov qauv siv. Tus thermanics, thermocoples, transmitters, thiab lwm yam yog cov twj paj nruag. Yog tias lawv tsis muaj qhov ntsuas tsis tau, lawv yuav dhau los ua qhov tsis raug thiab cuam tshuam rau cov khoom. Qee cov tuam txhab tau txhuam lawv cov khoom cub tag nrho vim yog cov thermirocurate thermoco, uas ua rau poob ntau pua txhiab yuaan.
Yog tias nws yog qhov tshiab thermocouple, muaj ntau lub tuam ntxhab tsuas yog kuaj xyuas thaum lub sijhawm calibration, uas txhais tau tias qhov tsim nyog ntawm qhov kev tsim nyog ntawm qhov kev tsim nyog tshiab tsis tau 100%. Yog li ntawd, nws yog qhov tsim nyog heev rau calibrate cov thibocouple tshiab.
Rau kev siv thermocouples, kev ua haujlwm ntev hauv cov dej siab muaj qhov cuam tshuam tseem ceeb ntawm lawv cov yam ntxwv ntsuas kub. Vim oxidation, corrosion, thiab lwm yam, cov khoom ntawm cov khoom yuav maj mam hloov, thiab cov cua nab kuab yuav muaj kev hloov pauv tau yooj yim, ua rau muaj qhov ntsuas kub tsis raug. Yog li ntawd, nws yog qhov yuav tsum tau ua kom tsis tu ncua calibrate thermocouples. Rau thermocouples uas tshaj qhov tsis muaj kev ua yuam kev, lawv yuav tsum tau hloov lossis lawv tau muab Welded, thiab tom qab ntawd tau txheeb xyuas kom tsim nyog ua ntej lawv siv tau.
Hauv kev tshawb xav, kev ntsuas hluav taws xob lub voj voog rau thermocouples feem ntau yog rau lub hlis, thiab rau cov seev theem nrab nws yog feem ntau 12 lub hlis. Hauv cov xwm txheej tshwj xeeb, nws tuaj yeem txiav txim siab raws li kev siv kev pab. Lub spmk series thermocouple kub thiab caij nplooj zeeg, ruaj khov tswj, me me, lub teeb hnyav, thiab yooj yim lam tau. Nws yog qhov haum rau kev ntsuas kub xws li thermetles, cov cua sov, thiab kub hloov mus rau hauv lub rooj sib tham, ntsuas chav, thiab ntsuas hluav taws xob, thiab ntsuas hluavtaws thiab ntsuas hluav taws xob.
