Dab tsi yog qhov sib txawv ntawm thermocouple thiab ib tug thermal resistor?

Thermocouples yog qhov ntsuas kub tshaj plaws hauv kev tswj kom tsis siv neeg, thiab muaj peev xwm siv hluav taws xob dav dav effect {. Thaum ob tus sib txawv los yog cov khoom siv kub no yuav raug tsim tawm hauv lub voj voos kev sib txawv, tseem muaj cov phiaj xwm pom kev sib txawv, ob lub peev xwm: qhov sib txawv kub sib txawv thiab tiv tauj cov peev xwm .

Ob qho laj thawj thermocus thiab thermal ua rau kev sib cuag kub ntsuas ntsuas ntsuas ntsuas qhov ntsuas kub ntawm kev ntsuas qhov ntsuas kub ntawm qhov ntsuas kub ntawm qhov ntsuas qhov ntsuas, hais tias lawv cov yam ntxwv thiab cov yam ntxwv tsis yog tib yam li. .
Thermoelectric muaj peev xwm yog hais txog cov peev xwm tsim los ntawm ob kawg ntawm tib qho chaw sib txawv, yog li lub peev xwm uas sib cuag tau sib cuag vim yog lawv cov hluav taws xob sib txawv, uas ua rau qee qhov kev sib txawv ntawm hluav taws xob diffusion {. Qhov loj ntawm kev sib cuag yog nyob ntawm ob tus neeg sib txawv ntawm ob tus sib txawv ntawm lawv cov lus sib tiv paus .
Muaj ob txoj kev teeb tsa ntawm thermocouples, hom dog dig thiab hom ua rog .
Cov xov xwm thermocouples feem ntau muaj cov hlua thermoco, cov tes tsho tiv no, cov ntaub thaiv npog ua ke ntawm cov khoom siv thermocouple tom qab sib dhos thiab ncab .
Cov hluav taws xob hluav taws xob yuav tsum tau siv cov xaim hluav taws xob tshwj xeeb uas yuav tsum tau muab faib rau cov xov tooj cua sib txawv Kev sib sau ua ke ntawm kev txuas hlau txuas ntxiv yog tib yam li cov hlau hluav taws xob tsis yog ua rau cov xaim hluav taws xob thiab cov khoom siv txuas ntxiv tus ncej ntawm thermocouple yog txuas nrog cov xaim liab ntawm cov xim uas tseem tshuav ntawm cov khoom siv uas tseem ceeb yog tooj liab-Nickel Alloy {}}

Kev xaiv ntawm thermocouples yuav tsum tau nyob ntawm kev ua haujlwm ntsuas kub, yuav tsum tau ua, kev ua haujlwm ntawm cov khoom ntsuas, kev kawm ntawm cov txiaj ntsig kev lag luam thiab cov txiaj ntsig kev lag luam .

3. Qhov xwm thiab lub xeev ntawm cov ntsuas ntsuas cuam tshuam rau kev xaiv ntawm thermocouples
Qhov ntsuas kub txav ntawm cov khoom txav, cov khoom siv vibrating yuav tsum muaj kev tiv thaiv kev tiv thaiv, thiab cov hluav taws xob tsis sib xws.
