Umgomo wokusebenza we-thermocouple

Izithako ezimbili ezihlukene ze-conductor (ezibizwa ngokuthi i-thermocouple wire noma i-electrode eshisayo) i-synthesis loop emikhawulweni yomibili, lapho izinga lokushisa le-junction emibili lingekho ngesikhathi esisodwa, kusekethe kuzokhiqiza amandla e-electromotive, lolu hlobo lwento ebizwa ngokuthi i-thermoelectric effect, kanye amandla e-electromotive abizwa ngokuthi amandla kagesi we-thermoelectric.I-Thermocouple iwukusebenzisa isimiso sokulinganisa izinga lokushisa, esisetshenziswa ngokuqondile ekulinganiseni izinga lokushisa eliphakathi nendawo sibizwa ngokuthi umsebenzi ekupheleni kokuphela (owaziwa nangokuthi uhlangothi lokulinganisa), esinye isiphetho sibizwa ngokuthi isiphetho esibandayo (esaziwa nangokuthi isinxephezelo) ;Isiphetho esibandayo esixhunywe kuthuluzi lokubonisa noma imitha, ithuluzi lokubonisa lizokhomba amandla e-thermocouple thermoelectric.

I-Thermocouple empeleni iwuhlobo lwesiguquli samandla, iguqula ukushisa kube ugesi, isebenzisa amandla kagesi we-thermoelectric akhiqizwa izinga lokushisa lokulinganisa, amandla e-thermocouple thermoelectric, kufanele inake le mibuzo elandelayo:

1, amandla e-thermocouple thermoelectric ezingeni lokushisa le-thermocouple kuzo zombili iziphetho zomsebenzi umsebenzi umpofu, kunokuba isiphetho esibandayo se-thermocouple esinomsebenzi, umehluko wezinga lokushisa kuzo zombili iziphetho zomsebenzi;

2, usayizi wamandla we-thermocouple we-thermoelectric akhiqizwa, lapho impahla ifana ne-thermocouple, ayihlanganise lutho nobude nobubanzi be-thermocouple, futhi kuphela ekugcineni kokwakheka kwezinto ze-thermocouple kanye nokwehluka kwezinga lokushisa;

3, lapho kunqunywa ukwakheka kwempahla ye-thermocouple ye-thermocouple wire thermocouple, usayizi wamandla we-thermocouple thermoelectric, uhlobene kuphela nomehluko wezinga lokushisa le-thermocouple;Uma ukugcinwa kwesiphetho esibandayo se-thermocouple, lokhu kumandla we-thermocouple thermoelectric kuwukuphela komsebenzi wenani elilodwa lezinga lokushisa.Izinto ezimbili ezihlukene zokushisela Ikhondatha noma i-semi-conductor A no-B, yenza iluphu engu-A evaliwe, njengoba kukhonjisiwe.Lapho i-conductor A no-B ezimbili eziqhubekayo umehluko wezinga lokushisa phakathi kuka-1 no-2, kwenzeka phakathi kwamandla e-electromotive, ngaleyo ndlela yakhe usayizi we-A wamanje kusekethe.I-Thermocouple isebenzisa lo mphumela ukuze isebenze.
