Thaum muaj qhov kub sib txawv ntawm qhov ntsuas qhov kawg thiab qhov kev siv kawg, lub peev xwm thermoelectric tsim tawm, thiab cov cuab yeej ua haujlwm qhia txog qhov ntsuas kub uas cuam tshuam rau lub peev xwm thermoelectric. Nws yog dav siv hauv kev tswj tsis siv neeg hauv kev lag luam tshuaj. Los ntawm cov ntsuas kub ntsuas, qhov ntsuas kub ntawm cov khoom tswj tau tuaj yeem hloov mus rau hauv cov teeb liab hluav taws xob los ntsuas ncaj qha thiab tswj qhov kub ntawm cov pa roj, kua, thiab vapors hauv cov txheej txheem tsim khoom. Yog tias siv cov thermocouples zoo tib yam, nws tsis muaj kev nyab xeeb heev thiab tuaj yeem ua rau cov pa tawg yooj yim. Yog li ntawd, nyob rau hauv cov xwm txheej no, kev tawg-pov thawj thermocouples yuav tsum tau siv los ua qhov ntsuas kub, raws li cov ntsuas ntsuas kub thiab tswj, sib phim nrog cov cuab yeej tso saib,? Txhawm rau ntsuas ncaj qha thiab tswj cov pa roj hauv cov txheej txheem tsim khoom.
Muaj qhov chaw sab hauv txaus, phab ntsa tuab thiab cov khoom siv dag zog, thiab thermal stability ntawm cov roj hmab sealing nplhaib ua tau raws li lub teb chaws tawg-pov thawj cov qauv. Thermocouples uas tshaj lub voj voog calibration tsis pub siv rau kev sib kis. Yog hais tias qhov tawg-pov thawj thermocouple tom qab calibration tsis siv lossis tsis tau siv tsawg dua 200 teev, qhov kub qis kawg yog qhov kawg dawb, uas feem ntau yog qhov kub thiab txias. Raws li kev sib raug zoo ntawm cov hluav taws xob hluav taws xob hluav taws xob thiab qhov kub thiab txias, qhov ntsuas kub ntsuas tau muab tso rau hauv ib qho los yog ob lub qhov siab aluminium insulated raj, thiab tom qab ntawd qhov ntsuas qhov kawg ntawm qhov ntsuas kub ntsuas yog sib npaug ntawm qhov ntsuas qhov kawg ntawm tus qauv thermocouple. Tus nqi hluav taws xob electromotive quab yuam ntsuas ntawm 1000 degree yog qhov sib txawv ntawm qhov ntsuas tus nqi ua ntej hloov qhov tob tob.
