Thermocouple yog ib hom kev ntsuas qhov ntsuas kub thiab ib hom ntsuas. Nws ncaj qha ntsuas qhov kub thiab txias, thiab hloov cov teeb liab kub rau hauv lub teeb liab thermoelectromotive quab yuam, uas yog hloov mus rau hauv qhov ntsuas kub ntawm qhov nruab nrab ntsuas los ntawm qhov ntsuas hluav taws xob (tseem ceeb ntsuas). Lub hauv paus ntsiab lus ntawm kev ntsuas kub ntawm thermocouple yog tias ob lub conductors ntawm cov khoom sib txawv tsim ib lub voj kaw. Thaum muaj qhov kub thiab txias ntawm ob qhov kawg, ib qho tam sim no yuav ntws hauv lub voj. Lub sijhawm no, muaj lub zog electromotive-thermoelectromotive quab yuam ntawm ob qhov kawg. Qhov no yog qhov hu ua Seebeck effect. Ob homogeneous conductors nrog cov khoom sib txawv yog cov thermoelectrodes. Qhov kawg nrog qhov kub siab dua yog qhov ua haujlwm kawg, thiab qhov kawg nrog qhov kub qis dua yog qhov kawg dawb. Qhov kawg dawb yog feem ntau ntawm qhov kub thiab txias. Raws li kev sib raug zoo ntawm cov thermoelectromotive quab yuam thiab qhov kub thiab txias, lub rooj ntsuas thermocouple yog tsim; Lub rooj ntsuas ntsuas tau txais thaum qhov kub dawb kawg ntawm 0 ℃, thiab cov thermocouples sib txawv muaj cov rooj sib txawv.
Thaum cov khoom siv hlau thib peb txuas nrog rau hauv lub thermocouple Circuit Court, tsuav yog qhov kub ntawm ob qhov sib txuas ntawm cov khoom yog tib yam, cov khoom siv hluav taws xob uas tsim los ntawm cov thermocouple yuav nyob twj ywm tsis hloov, uas yog, nws yuav tsis cuam tshuam los ntawm qhov thib peb. hlau hauv Circuit Court. Yog li ntawd, thaum lub thermocouple ntsuas qhov ntsuas kub, qhov ntsuas ntsuas tuaj yeem txuas nrog, thiab qhov ntsuas kub ntawm qhov ntsuas nruab nrab tuaj yeem paub tom qab ntsuas qhov ntsuas kub.
