Chaza ngokuningiliziwe izimo zokukala izinga lokushisa le-thermocouple

Thermocoupleiwuhlobo lwesici esizwa izinga lokushisa, iwuhlobo lwensimbi, i-i-thermocouple ikala izinga lokushisa ngokuqondile. Iluphu evaliwe eyakhiwe amakhondatha amabili anezinto zokwakha ezihlukile. Ngenxa yezinto ezihlukene, ukuminyana kwama-electron ahlukene kukhiqiza ukusabalalisa kwe-electron, futhi amandla akhiqizwa ngemva kokulingana okuzinzile. Uma kukhona izinga lokushisa legradient emikhawulweni yomibili, i-current izokhiqizwa ku-loop, futhi amandla e-thermoelectromotive azokhiqizwa. Uma umehluko wezinga lokushisa mkhulu, mkhulu owamanje. Ngemva kokulinganisa amandla e-thermoelectromotive, inani lokushisa lingaziwa. Empeleni, i-i-thermocouple iyisiguquli samandla esiguqula amandla ashisayo abe amandla kagesi.

Izinzuzo zobuchwepheshe zama-ama-i-thermocouples:ama-i-thermocouplesabe nebanga elibanzi lokulinganisa izinga lokushisa nokusebenza okuzinzile; ukunemba kokulinganisa okuphezulu, i-i-thermocouple ithintana ngokuqondile nento elinganisiwe, futhi ayithinteki phakathi nendawo ephakathi; isikhathi sokuphendula esishisayo siyashesha, futhi i-i-thermocouple iyazwela ekushintsheni kwezinga lokushisa; Ibanga lokulinganisa likhulu, i-i-thermocouple ingakala izinga lokushisa ngokuqhubekayo ukusuka ku -40~+1600℃; ii-thermocoupleinokusebenza okuthembekile namandla amahle wokukhanda. Impilo yesevisi ende nokufakwa okulula. Lo mbhangqwana we-galvanic kufanele wakhiwe ngezinto ezimbili zokuqhuba (noma ze-semiconductor) ezinezakhiwo ezahlukahlukene kepha zihlangabezana nezidingo ezithile zokwenza iluphu. Kufanele kube khona umehluko wokushisa phakathi kwe-terminal yokukala ne-terminal reference ye-i-thermocouple.

Amakhondakta noma ama-semiconductors A no-B ezinto ezimbili ezihlukene ashiselwa ndawonye ukuze akhe iluphu evaliwe. Uma kunomehluko wezinga lokushisa phakathi kwamaphuzu amabili okunamathiselwe okungu-1 no-2 wamakhondatha A no-B, amandla e-electromotive akhiqizwa phakathi kokubili, ngaleyo ndlela kwakhe umsinga omkhulu kuluphu. Lesi simo sibizwa ngokuthi umphumela we-thermoelectric. Ama-Thermocouples asebenza esebenzisa lo mphumela.
