AK-hom thermocouple yog ib qho khoom siv ntsuas kub uas muaj ob lub xov hlau ua los ntawm cov khoom sib txawv. Thaum ob lub xov hlau sib txuas ua ke, lawv tsim ib qho hluav taws xob sib txuas. Yog tias qhov kub thiab txias hloov ntawm qhov kev sib tshuam no, nws tsim ib qho hluav taws xob uas tuaj yeem txhais tau tias qhov kub thiab txias. Qhov no feem ntau hu ua "Seebeck effect."
Cov yam ntxwv ntawm lub nplhaib thermocouple hom k
Thermocouple yog ib qho ntawm cov khoom siv ntsuas kub tshaj plaws hauv kev lag luam. Nws yuav tsum tau nruab nrog ib tug thib ob ntsuas, thiab nws zoo yog:
① Kev ntsuas qhov tseeb. Vim tias cov thermocouples tuaj yeem hu ncaj qha rau cov khoom kuaj, lawv tsis cuam tshuam los ntawm qhov nruab nrab nruab nrab.
② Kev ntsuas dav dav. Cov thermocouples feem ntau tuaj yeem ntsuas tsis tu ncua ntawm 0 txog +200 degree, thaum qee qhov tshwj xeeb thermocouples tuaj yeem ntsuas qhov ntsuas kub qis li -269℃(xws li kub hlau nickel chromium) thiab mus txog +2800℃(xws li tungsten rhenium).
③ Kev tsim kho yooj yim thiab siv tau yooj yim. Thermocouples feem ntau yog tsim los ntawm ob hom hlau hlau, thiab tsis txwv los ntawm qhov loj lossis pib. Lawv muaj lub tes tsho tiv thaiv sab nraud, ua rau lawv yooj yim heev rau siv.
Cov txheej txheem los ntsuas qhov zoo ntawm lub nplhaib thermocouple hom k
1. Saib xyuas ntawm qhov muag liab qab seb lub raj tiv thaiv puas yog corroded thiab nkag mus, txawm tias nws yog to, thiab lwm yam.
2. Siv multimeter los ntsuas qhov txuas ntxiv. Qhov tsis kam ntawm cov thermocouple sib sau ua ke feem ntau tsis ntau dua 2 ohms, thiab qhov tsis kam ntawm stainless hlau braided hlau hom feem ntau tsis ntau dua 50 ohms. Feem ntau, yog tias nws loj dua 1K, nws tuaj yeem txiav txim siab tawg.
3. Siv lub multimeter los ntsuas tus nqi kuj. Resistor tshaj 100K yog qhov tsis zoo.
4. Siv txoj kev ntsuas multimeter ohm los ntsuas, kho qhov tsis kam, txuas ob qhov kawg, thiab siv lub teeb kom kub me ntsis. Yog hais tias lub multimeter pointer pom tseeb ua loj los yog me me, nws txhais tau tias nws yog qhov zoo. Yog tias tus taw tes tsis txav, nws txhais tau tias nws tawg.
5. Siv lub multimeter los ntsuas qhov voltage ntawm ob qho kawg. Yog tsis muaj hluav taws xob, nws tawg
