Iwuhlobo lwesici esizwa izinga lokushisa, iwuhlobo lwensimbi, ukulinganisa izinga lokushisa kwe-thermocouple ngokuqondile.Yakhiwe ngezinto ezimbili ezihlukene zokubunjwa kwe-loop evaliwe yomqhubi, ngoba impahla ihlukile, ukusabalalisa kwe-electron ehlukene ye-electron density, ukulingana okuzinzile kukhiqizwa ngemva kwamandla kagesi.Uma i-gradient yezinga lokushisa isemikhawulweni yomibili, iluphu izoba yamanje, ikhiqize ama-emfs e-thermoelectric, uma umkhulu umehluko wezinga lokushisa, i-current izoba mkhulu.Ukwazi izinga lokushisa ngemuva kwe-emfs ye-thermoelectric elinganiselwe.I-Thermocouple, empeleni, iwuhlobo lwesiguquli samandla, ingaguqula ukushisa kube ugesi.
Izinzuzo zobuchwepheshe be-Thermocouple: ububanzi bokulinganisa izinga lokushisa le-thermocouple kanye nokusebenza okuzinzile kokuqhathanisa;Ukunemba okuphezulu kokulinganisa, ukuthintana okuqondile kwe-thermocouple nento elinganiswayo, okungathinteki okuphakathi nendawo;Isikhathi sokuphendula esishisayo siyashesha, impendulo eguquguqukayo ye-thermocouple ekushintsheni kwezinga lokushisa;Ibanga elibanzi lokulinganisa, i-thermocouple esuka ku-40 ~ + 1600 ℃ ingaba isilinganiso sokushisa esiqhubekayo;Ukusebenza kwe-thermocouple kuzinzile, amandla amahle wemishini.Impilo ende yokusebenzisa, idivayisi yesidlo sasemini.
Umbhangqwana we-galvanic kufanele wakhiwe ngemvelo emibili ehlukene kodwa uvumelane nezidingo ezithile ze-conductor noma izinto ze-semiconductor zakha iluphu.Isilinganiso se-thermocouple kufanele sibe nomehluko wezinga lokushisa phakathi kohlangothi nereferensi.
I-conductor yolwazi emibili ehlukene noma i-semiconductor welding, A no-B bakha iluphu engu-A evaliwe.Lapho ukhondatha A no-B umehluko wezinga lokushisa eliqhubekayo phakathi kuka-1 no-2, uvela phakathi kwamandla e-electromotive, ngakho-ke hlanganisa usayizi we-A wamanje kwisekethe, lolu hlobo lwento ebizwa ngokuthi umphumela we-thermoelectric.I-Thermocouple isebenzisa lo mphumela ukuze isebenze.
