Hom thermocoples thiab cov ncauj lus ntxaws ntxaws ntawm cov ntaub ntawv

Feem ntau siv thermocouples feem ntau muab faib ua ob pawg: qauv thermocoorples thiab cov thermoco zog. Tus txheem thermocouple yog hais txog qhov thermocoupric uas muaj peev xwm kev sib raug zoo thiab kev sib raug zoo, thiab kev ua yuam kev ntawm lub teb chaws. Nws muaj cov khoom sib txuam tso saib rau kev xaiv. Tsis yog-txheem thermocouples tsis zoo raws li qauv thermocouples nyob rau hauv cov nqe lus ntawm kev siv ntau yam, thiab feem ntau tsis muaj kev sib koom ua ke. Lawv feem ntau yog siv rau kev ntsuas hauv qee lub sijhawm tshwj xeeb. Qauv xwm txheej thermocoened txij Lub Ib Hlis 1, 1988, Suav teb cov qauv thermoco, thiab tsim muaj xya tus qauv siv hluav taws xob nrog rau cov tshuab hluav taws xob.
