Yuav Ua Li Cas Xaiv Thermocouples thiab thermal resistors

Ua ntej, cia kuv qhia thermocouple. Thermocouple yog qhov siv kub tshaj plaws hauv kev ntsuas kub. Nws lub ntsiab tseem ceeb yog kev ntsuas dav ntau, qauv ruaj khov, thiab muaj peev xwm hloov kho qhov kub thiab txias rau kev tswj kom tsis siv neeg thiab tswj hwm nruab nrab.
Qhov ntsuas kub ntsuas ntawm kev ntsuas kub ntawm thermocouple yog raws li thermoelectric nyhuv. Thaum ob tus neeg sib txawv lossis cov semiconductors txuas rau hauv lub voj kaw, thaum ntsuas kub ntawm ob lub zog sib txawv, thermoelectric peev xwm yuav tsim tawm hauv lub voj. Qhov tshwm sim no hu ua thermoelectric nyhuv, tseem hu ua Showbeck nyhuv.
Lub thermoelectric peev xwm tsim nyob rau hauv lub voj kaw muaj ob lub peev xwm: Thermoelectric muaj peev xwm thiab muaj peev xwm tiv tauj. 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. Raws li lub npe qhia, kev sib cuag cov npe yog hais txog cov peev xwm tsim tau thaum ob tus neeg sib txawv tau sib cuag vim yog lawv cov hluav taws xob sib txawv. Thaum lawv mus txog ib qho kev tshuav nyiaj li cas, qee qhov nyiaj ntawm hluav taws xob diffusion yog tsim. 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 tswj hwm thoob ntiaj teb tau muab faib ua 11Tus qhov chaw sib faib ua ke, yog J, K, N, thiab tus lej siab tshaj plaws tuaj yeem ncav cuag 1800 degrees Celsius. Ntawm lawv, R, S, B, G, C, thiab yog cov khoom siv hlau kub, thiab cov tseem tshuav uas yog hu ua pheej hlau hlau thermoco.
Muaj ob qho kev sib txawv ntawm thermocouples, sib dhos yam thiab hom armored. Los ua ke hom thermocouples feem ntau muaj ntawm thermocouples, cov ntaub qhwv thermocoup, thaum lub tes tsho insulating thiab cov tes tiv thaiv hlau sib sau ua ke thiab ncab.
Txawm li cas los xij, lub ntsiab ntsuas hluav taws xob ntawm thermocouple yuav tsum muaj cov hlau tshwj xeeb los xa, uas peb hu rau cov roj teeb Thermocouple. Qhov sib txawv ntawm thermoco yuav tsum muaj cov xov tooj sib txawv, uas yog qhov kev paub tseeb ntawm qhov chaw txias, yog li qhov kub ntawm qhov siv kawg yog qhov ruaj khov. Cov xov cov xov hlau muab faib ua cov hom nyiaj ntsuab thiab txuas ntxiv. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau txuas ntxiv yog tib yam li cov neeg hlau ntsuas, tab sis hauv kev coj ua, qhov sib txuas txuas ntxiv tsis tsim los ntawm cov hlau tib yam li thermocouple. Nws yog feem ntau hloov los ntawm xaim nrog tib lub zog thermoelectric muaj peev xwm ua qhov thermocouple.
Kev sib txuas ntawm cov xaim hluav taws xob thiab thermocouple yog yooj yim thiab meej, thiab tuaj yeem txuas nrog kev tshaj tawm thermocouple connector. Feem ntau ntawm cov xov cov xov feem dav dav dav yog ua los ntawm tooj liab-nickel alloy.

Tom ntej no, cia qhia cov cua sov thermal. Txawm hais tias qhov thermal resesors tau siv dav hauv kev lag luam, lawv daim ntawv thov raug txwv rau qee yam vim lawv qhov ntsuas kub ntau. Qhov ntsuas kub ntsuas ntawm cov thermal resistors yog raws tus yam ntxwv uas cov nqi tiv thaiv ntawm tus neeg saib xyuas lossis cov teeb meem hloov nrog kub.

Nws muaj ntau yam zoo, thiab tseem tuaj yeem kis cov cim hluav taws xob remotely, nrog siab intertivity, tab sis nws yuav tsum tau ntsuas kev hloov kho qhov kub thiab tsis tuaj yeem ntsuas qhov kub hloov tam sim no.
Muaj cov tshuab thermal feem ntau siv PT100, PT10, CUES50, CUES50, thiab tseem muaj cov khoom lag luam tseem pt1000 thiab PT200.

Qhov ntsuas kub ntawm platinum thermal thermal thermal feem ntau yog 5000 degrees capsius, thiab cov neeg tooj liab resistors feem ntau yog 400 degrees Celsius. Feem ntau hais lus, tus nqi ntawm tus nqi ntawm cov ua tiav thermal yog kim tshaj li ntawm thermocouples, thiab lawv ruaj ruaj ruaj raws li qhov thermocouples.
