Isingeniso:

Ezinqubweni zokukhiqiza zezimboni, izinga lokushisa lingenye yemingcele ebalulekile edinga ukulinganiswa nokulawulwa. Esilinganisweni sokushisa, ama-thermocouples asetshenziswa kabanzi. Zinezinzuzo eziningi, njengesakhiwo esilula, ukukhiqiza okulula, ububanzi bokulinganisa okubanzi, ukunemba okuphezulu, inertia encane, kanye nokudluliswa okulula kwamasiginali okukhipha kude. Ngaphezu kwalokho, ngenxa yokuthi i-thermocouple iyinzwa yokwenziwa, ayidingi ukunikezwa kwamandla kwangaphandle ngesikhathi sokulinganisa, futhi kulula kakhulu ukuyisebenzisa, ngakho-ke ivame ukusetshenziselwa ukukala izinga lokushisa legesi noma uketshezi ezithandweni nasemapayipini nangaphezulu. izinga lokushisa lokuqinile.

Isimiso sokusebenza:

Lapho kukhona ama-conductor amabili ahlukene noma ama-semiconductors A no-B ukuze akhe iluphu, futhi iziphetho ezimbili zixhunywe komunye nomunye, inqobo nje uma amazinga okushisa ezinhlangothini zombili ehlukile, izinga lokushisa kwelinye icala ngu-T, elibizwa ngokuthi ukuphela okusebenzayo noma ukuphela okushisayo, futhi izinga lokushisa lenye i-T0, elibizwa ngokuthi i-free end (ebizwa nangokuthi ukuphela kwereferensi) noma ukuphela okubandayo, amandla e-electromotive azokhiqizwa ku-loop, kanye nesiqondiso nobukhulu be-loop. amandla e-electromotive ahlobene nempahla yomqhubi kanye nezinga lokushisa lalezi zindlela ezimbili. Lesi simo sibizwa ngokuthi "umphumela we-thermoelectric", futhi i-loop eyakhiwe ngama-conductor amabili ibizwa ngokuthi "thermocouple".

Amandla we-thermoelectromotive aqukethe izingxenye ezimbili, ingxenye eyodwa ingamandla okuxhumana e-electromotive amakhondaktha amabili, kanti enye ingxenye amandla e-thermoelectric electromotive ye-conductor eyodwa.

Ubukhulu bamandla we-thermoelectromotive ku-loop ye-thermocouple buhlobene kuphela nempahla ye-conductor ehlanganisa i-thermocouple kanye nezinga lokushisa lama-junctions amabili, futhi ayihlangene nhlobo nokuma nobukhulu be-thermocouple. Uma izinto ezimbili zama-electrode ze-thermocouple zilungisiwe, amandla e-thermoelectromotive amazinga okushisa e-junction amabili u-t no-t0. umsebenzi awulungile.
