Qhov kev them nqi txias txias rau cov thermoco

Thaum ntsuas qhov kub thiab txias nrog lub thermocouple, nws yog qhov yuav tsum tau txuas nrog qhov kawg, yog li ntawd qhov kev ntsuas kub kawg, thiab qhov kawg ntawm nws lub peev xwm ntawm kev ntsuas ntsuas yog qhov ntsuas kub. Yog tias qhov ntsuas kub hloov thaum lub sij hawm txias kawg thaum ntsuas, nws yuav cuam tshuam qhov tseeb ntawm qhov ntsuas tau. Siv qee yam kev ntsuas kom them rau qhov cuam tshuam los ntawm kev hloov kub thaum lub sijhawm them txias kawg ntawm thermocouples.
Qhov kev them nyiaj txias kawg ntawm thermocouples feem ntau siv tus choj sib txuas ntawm lub tshuab cua sov sib txuas nyob rau hauv koob nyob rau hauv lub txias txias. Peb caj npab ntawm tus choj yog cov qauv tiv taus, thiab sab caj npab yog suav nrog (tooj liab) tus nab. Thaum qhov ntsuas kub ntawm qhov hloov txias txias (xws li nce zuj zus los ntawm Thermocoelle yuav tau hloov pauv, ua rau cov hluav taws xob tsis kam pauv, ua rau cov hluav taws xob hloov pauv (nce). Yog tias cov tsis tau xaiv tau zoo thiab cov hluav taws xob yog qhov tseeb, thiab tag nrho cov zis hluav taws xob (peev xwm) ntawm tag nrho cov hluav taws xob ntsuas qhov ntsuas qhov ntsuas kub. Nov yog lub hauv paus ntsiab lus ntawm kev sib tshuam txias rau thermocouples.
But the thermistor does not require cold end compensation, because the so-called "cold end compensation" refers to the measurement of the thermoelectric potential of the thermocouple based on 0 degrees, and it does not require an excitation source. Thiab qhov ntsuas yog nyob ntawm chav sov so, yog li rau kev ntsuas thermocoup, nws tsis ntsuas ntawm {2}} degrees, uas ua rau ntsuas ntsuas tsis raug. Yog li hauv Circuit Court ntawm lub twj paj nruag, feem ntau muaj kev them nyiaj txias kawg kawg.
