Umgaqo osebenzayo we-thermocouple

Izithako ezibini ezahlukeneyo ze-conductor (ebizwa ngokuba yi-thermocouple wire okanye i-electrode eshushu) iluphu ye-synthesis kuzo zozibini iziphelo, xa iqondo lobushushu lentlupheko lingekho ngaxeshanye, kwisekethe iyakuvelisa amandla e-electromotive, olu hlobo lwento ebizwa ngokuba yi-thermoelectric effect, kwaye amandla e-electromotive ebizwa ngokuba yi-thermoelectric potential.I-Thermocouple kukusebenzisa umgaqo womlinganiselo wobushushu, osetyenziswa ngokuthe ngqo ekulinganiseni ubushushu obuphakathi ubizwa ngokuba ngumsebenzi ekupheleni kwesiphelo (ekwaziwa ngokuba licala lokulinganisa), elinye isiphelo libizwa ngokuba lisiphelo esibandayo (esaziwa ngokuba yimbuyekezo) ;Isiphelo esibandayo esiqhagamshelwe kwisixhobo sokubonisa okanye imitha, isixhobo sokubonisa siya kubonisa amandla e-thermocouple thermoelectric.

I-Thermocouple ngokwenene luhlobo lwesiguquli samandla, siguqula ubushushu bube ngumbane, sisebenzisa amandla e-thermoelectric aveliswa ngumlinganiselo wobushushu bokulinganisa, ngenxa yesakhono se-thermocouple thermoelectric, kufuneka sinikele ingqalelo kule mibuzo ilandelayo:

I-1, i-thermocouple enokuthi i-thermoelectric kwiqondo lobushushu le-thermocouple kuzo zombini iziphelo zomsebenzi umsebenzi uhlwempuzekile, kunokuba isiphelo esibandayo se-thermocouple kunye nomsebenzi, umehluko weqondo lokushisa kuzo zombini iziphelo zomsebenzi;

I-2, ubukhulu be-thermocouple thermoelectric potential eveliswa, xa izinto zifana ne-thermocouple, azinanto yakwenza nobude kunye nobubanzi be-thermocouple, kwaye kuphela ekupheleni kokwakheka kwezinto ze-thermocouple kunye nokwahlukana kobushushu;

3, xa i-thermocouple wire thermocouple i-thermocouple yokwakheka kwezinto imiselwe, ubungakanani be-thermocouple thermoelectric enokubakho, ehambelana kuphela kunye nokwahlukana kobushushu be-thermocouple;Ukuba isiphelo esibandayo sokugcina ubushushu be-thermocouple, oku kwi-thermocouple thermoelectric potential kuphela kukuphela komsebenzi wexabiso elinye lobushushu.Izinto ezimbini zokuwelda ezahlukeneyo I-conductor okanye i-semi-conductor A kunye no-B, yenza i-loop evaliweyo, njengoko kubonisiwe.Xa i-conductor A kunye ne-B ezimbini eziqhubekayo umehluko weqondo lokushisa phakathi kwe-1 kunye ne-2, kwenzeka phakathi kwamandla e-electromotive, ngaloo ndlela kwakheka ubungakanani be-A yangoku kwisekethe.I-Thermocouple isebenzisa le mpembelelo ukusebenza.
