Nws yog ib hom kev ntsuas qhov ntsuas kub, yog ib hom kev ntsuas, ntsuas qhov ntsuas kub ntawm thermocouple ncaj qha.Ua los ntawm ob yam khoom sib txawv ntawm tus neeg xyuas pib kaw lub voj, vim tias cov khoom sib txawv, qhov sib txawv ntawm electron diffusion ntawm electron ceev, ruaj khov equilibrium yog tsim tom qab hluav taws xob muaj peev xwm.Thaum kub gradient nyob rau ntawm ob qho kawg, lub voj yuav tam sim no, tsim cov thermoelectric emfs, qhov sib txawv ntawm qhov kub thiab txias, qhov ntau dua qhov tam sim no.Kom paub qhov kub thiab txias tom qab ntsuas qhov ntsuas kub emfs.Thermocouple yog, qhov tseeb, ib yam ntawm lub zog hloov pauv, tuaj yeem hloov cov cua sov rau hauv hluav taws xob.
Thermocouple technical zoo: dav thermocouple ntsuas kub ntau thiab ruaj khov kev sib piv;Kev ntsuas siab raug, thermocouple ncaj qha kev sib cuag nrog cov khoom raug ntsuas, tsis cuam tshuam los ntawm qhov nruab nrab nruab nrab;Thermal teb lub sij hawm yog ceev, saj zawg zog thermocouple teb rau kub hloov;Kev ntsuas dav dav, thermocouple los ntawm 40 ~ + 1600 ℃ tuaj yeem ntsuas qhov ntsuas kub tsis tu ncua;Thermocouple kev ua tau zoo yog ruaj khov, zoo txhua yam muaj zog.Ntev siv lub neej, khoom siv rau noj su.
Galvanic ob peb yuav tsum muaj ob qhov sib txawv tab sis haum rau qee qhov kev xav tau ntawm tus neeg xyuas pib lossis cov khoom siv semiconductor ua ib lub voj.Kev ntsuas thermocouple yuav tsum muaj qhov sib txawv ntawm qhov sib txawv ntawm sab thiab siv.
Ob qhov sib txawv cov ntaub ntawv tus neeg xyuas pib lossis semiconductor welding, A thiab B yog A kaw voj.Thaum tus neeg xyuas pib A thiab B ob qhov sib txawv ntawm qhov sib txawv ntawm 1 thiab 2, tshwm sim ntawm lub zog hluav taws xob, yog li tsim qhov loj ntawm A tam sim no hauv Circuit Court, qhov tshwm sim zoo li no hu ua cov nyhuv thermoelectric.Thermocouple siv cov nyhuv no los ua haujlwm.
