Yuav ua li cas thermouvles ua haujlwm

Thermocouple yog qhov ntsuas kub. Nws cov yeeb yam tseem ceeb yog qhov dav ntsuas kub thiab ntsuas qhov ntsuas kub ruaj khov. Nyob rau tib lub sijhawm, nws muaj cov lus teb yooj yim, zoo teb, thiab tuaj yeem xa cov cim hluav taws xob remotely, uas yooj yim thiab tswj hwm yooj yim. Qhov ntsuas kub ntawm kev ntsuas kub ntawm thermocouple yog raws li kev sib txuas ob tus neeg sib txawv lossis semiconductors rau hauv lub voj kaw. Thaum lub ntsuas kub ntawm ob lub junctions sib txawv, ib lub peev xwm thermoeltric yuav tsim tawm hauv lub voj. Qhov tshwm sim no hu ua, tseem hu ua. Lub thermoelectric peev xwm tsim nyob rau hauv lub voj kaw muaj ob lub peev xwm, "thermoelectric peev xwm" thiab "hu rau lub peev xwm". Thermoelectric muaj peev xwm hais txog cov peev xwm tsim los ntawm ob xaus ntawm tib tus neeg saib xyuas vim muaj ntau kub. Cov neeg sib txawv muaj cov hluav taws xob sib txawv, yog li lub peev xwm lawv tsim kuj txawv. Hu rau cov peev xwm yog hais txog cov peev xwm thaum ob tus neeg sib txawv tau sib cuag vim tias lawv cov hluav taws xob hluav taws xob sib txawv, yog li qee yam ntawm hluav taws xob sib txawv tshwm sim. Qhov loj ntawm kev sib cuag yog nyob ntawm cov khoom siv ntawm ob tus neeg sib txawv thiab ntsuas kub ntawm lawv cov ntsiab lus kub.

Tam sim no, thermocouples siv thoob ntiaj teb muaj tus qauv kev paub tseeb. Cov kev cai tswj hwm thoob ntiaj teb tau muab faib ua yim qhov sib txawv, thiab kub thiab txias 2700 27% yog 1800 degrees Celsius. Ntawm lawv, B, R, thiab S yog rau lub platinum series ntawm thermocouples. Txij li thaum Platinum yog ib qho khoom siv platinum, lawv kuj tau hu ua muaj nuj nqis hlau thermoco thermoco thermoco thermocots.
