Lub thermocouple yog ib qho kev ntsuas kub uas feem ntau siv hauv cov ntsuas kub. Nws ncaj qha ntsuas qhov ntsuas kub thiab hloov cov teeb liab kub rau hauv lub ntsuas hluav taws xob muaj peev xwm, uas yog tom qab ntawd hloov mus rau qhov ntsuas kub ntawm qhov nruab nrab ntsuas los ntawm cov cuab yeej hluav taws xob (cov cuab yeej thib ob).
Cov tsos ntawm ntau yam thermocouples feem ntau txawv heev nyob ntawm daim ntawv thov, tab sis lawv cov qauv yooj yim feem ntau yog tib yam. Lawv feem ntau muaj cov khoom tseem ceeb xws li thermoelement, lub tes tsho insulating, lub raj tiv thaiv, thiab lub thawv sib txuas. Lawv feem ntau yog siv ua ke nrog cov cuab yeej tso saib, cov cuab yeej kaw, thiab cov tswj hluav taws xob.
Hauv cov txheej txheem tsim khoom, qhov kub thiab txias yog ib qho tseem ceeb uas yuav tsum tau ntsuas thiab tswj. Thermocouples yog dav siv nyob rau hauv qhov ntsuas kub vim lawv ntau qhov zoo, nrog rau cov qauv yooj yim, yooj yim ntawm kev tsim khoom, kev ntsuas dav dav, qhov tseeb siab, qis inertia, thiab yooj yim ntawm cov teeb liab kis tau tus mob.
Tsis tas li ntawd, vim hais tias thermocouples yog passive sensors, lawv tsis xav tau ib qho hluav taws xob sab nraud rau kev ntsuas, ua rau lawv yooj yim heev rau siv. Yog li ntawd, lawv feem ntau siv los ntsuas qhov kub ntawm cov pa roj lossis cov kua dej hauv qhov cub thiab cov kav dej, nrog rau qhov kub thiab txias ntawm cov khib nyiab.
