Isingeniso：

Ezinqubweni zokukhiqiza zezimboni, izinga lokushisa lingenye yemingcele ebalulekile edinga ukukalwa nokulawulwa. Ekulinganisweni kwezinga lokushisa, ama-thermocouple asetshenziswa kabanzi. Anezinzuzo eziningi, njengesakhiwo esilula, ukukhiqizwa okulula, ububanzi bokulinganisa, ukunemba okuphezulu, ukungabi namandla okuncane, kanye nokudluliselwa okulula kwezimpawu zokukhipha. Ngaphezu kwalokho, ngenxa yokuthi i-thermocouple iyinzwa engasebenzi, ayidingi ukunikezwa kwamandla kwangaphandle ngesikhathi sokulinganisa, futhi kulula kakhulu ukuyisebenzisa, ngakho-ke ivame ukusetshenziselwa ukukala izinga lokushisa legesi noma uketshezi ezithandweni nasemapayipini kanye nokushisa okuphezulu kwezinto eziqinile.

Isimiso Sokusebenza:

Uma kunabaqondisi ababili abahlukene noma ama-semiconductor u-A no-B ukwakha iluphu, futhi iziphetho ezimbili zixhumene, inqobo nje uma amazinga okushisa ezindaweni ezimbili zokuhlangana ehlukene, izinga lokushisa lokuphela kolunye lingu-T, elibizwa ngokuthi ukuphela okusebenzayo noma ukuphela okushisayo, kanti izinga lokushisa lolunye uhlangothi lingu-T0, elibizwa ngokuthi ukuphela okukhululekile (okubizwa nangokuthi ukuphela kokubhekisela) noma ukuphela okubandayo, kuzokhiqizwa amandla e-electromotive ku-luphu, futhi isiqondiso nobukhulu bamandla e-electromotive kuhlobene nezinto zomqhubi kanye nokushisa kwezihlanganisi ezimbili. Lesi simo sibizwa ngokuthi “umphumela we-thermoelectric”, kanti iluphu eyakhiwe ngabaqondisi ababili ibizwa ngokuthi “i-thermocouple”.

Amandla e-thermoelectromotive aqukethe izingxenye ezimbili, ingxenye eyodwa iyi-contact electromotive force yama-conductor amabili, kanti enye ingxenye iyi-thermoelectric electromotive force yomqhubi oyedwa.

Ubukhulu bamandla e-thermoelectromotive ku-loop ye-thermocouple buhlobene kuphela nezinto zomqhubi ezakha i-thermocouple kanye nokushisa kwezindawo ezimbili ezihlanganayo, futhi abuhlobene nokuma nosayizi we-thermocouple. Lapho izinto ezimbili ze-electrode ze-thermocouple zizinzile, amandla e-thermoelectromotive yizinga lokushisa lezindawo ezimbili ezihlanganayo u-t no-t0. umsebenzi awubi.
