Chiyambi:

M'njira zopangira mafakitale, kutentha ndi chimodzi mwazinthu zofunika kuziyeza ndikuwongolera. Poyezera kutentha, ma thermocouples amagwiritsidwa ntchito kwambiri. Amakhala ndi zabwino zambiri, monga mawonekedwe osavuta, kupanga kosavuta, kusiyanasiyana koyezera, kulondola kwambiri, inertia yaying'ono, komanso kufalitsa kosavuta kwa ma siginecha akutali. Kuphatikiza apo, chifukwa thermocouple ndi sensa yopanda kanthu, sifunikira mphamvu yakunja panthawi yoyezera, ndipo ndiyosavuta kugwiritsa ntchito, chifukwa chake imagwiritsidwa ntchito kuyeza kutentha kwa gasi kapena madzi mu ng'anjo ndi mapaipi ndi kutentha kwapamtunda kwa zolimba.

Mfundo Yogwirira Ntchito:

Pamene pali awiri osiyana conductors kapena semiconductors A ndi B kupanga kuzungulira, ndi malekezero awiri olumikizidwa kwa wina ndi mzake, malinga ngati kutentha pa mphambano ziwiri zosiyana, kutentha kwa mapeto amodzi ndi T, amene amatchedwa mapeto ntchito kapena mapeto otentha, ndi kutentha kwa mapeto ena ndi T0 , amatchedwanso ufulu mapeto (omwe amatchedwanso mapeto a mafotokozedwe) kapena malekezero ozungulira adzakhala ndi mphamvu yamagetsi ndi mphamvu yamagetsi. Kukula kwa mphamvu ya electromotive kumakhudzana ndi zinthu za conductor ndi kutentha kwa magawo awiriwa. Chodabwitsa ichi chimatchedwa "thermoelectric effect", ndipo lupu lopangidwa ndi ma conductor awiri amatchedwa "thermocouple".

Mphamvu ya thermoelectromotive imakhala ndi magawo awiri, gawo limodzi ndi mphamvu yamagetsi yamagetsi ya ma conductor awiri, ndipo gawo lina ndi thermoelectric electromotive force ya conductor imodzi.

Kukula kwa mphamvu ya thermoelectromotive mu thermocouple loop kumangogwirizana ndi zinthu zochititsa chidwi zomwe zimapanga thermocouple ndi kutentha kwa magawo awiriwa, ndipo sizikugwirizana ndi mawonekedwe ndi kukula kwa thermocouple. Pamene zipangizo ziwiri za electrode za thermocouple zikhazikika, mphamvu ya thermoelectromotive ndiyo kutentha kwapakati pa t ndi t0. ntchito ndi osauka.
