Chiyambi:

Munjira zopangira mafakitale, kutentha ndi chimodzi mwazinthu zofunika kuziyeza ndikuwongolera.Poyezera kutentha, ma thermocouples amagwiritsidwa ntchito kwambiri.Iwo ali ndi zabwino zambiri, monga kapangidwe kosavuta, kupanga kosavuta, kusiyanasiyana koyezera, kulondola kwambiri, kuzizira pang'ono, komanso kufalitsa kosavuta kwazizindikiro zakutali.Kuphatikiza apo, chifukwa thermocouple ndi sensa yokhazikika, safuna mphamvu yakunja pakuyezera, ndipo ndiyosavuta kugwiritsa ntchito, chifukwa chake imagwiritsidwa ntchito kuyeza kutentha kwa gasi kapena madzi mu ng'anjo ndi mapaipi ndi pamwamba. kutentha kwa zolimba.

Mfundo Yogwirira Ntchito:

Pakakhala ma conductors awiri kapena ma semiconductors A ndi B kuti apange loop, ndipo malekezero awiriwo amalumikizana wina ndi mzake, malinga ngati kutentha pamagulu awiriwo kuli kosiyana, kutentha kwa mbali imodzi ndi T, yomwe imatchedwa ntchito mapeto kapena yotentha mapeto, ndi kutentha kwa mapeto ena ndi T0 , wotchedwa ufulu mapeto (omwe amatchedwanso mapeto mapeto) kapena mapeto ozizira, ndi electromotive mphamvu adzakhala kwaiye mu kuzungulira, ndi malangizo ndi ukulu wa electromotive mphamvu zimagwirizana ndi zinthu za kondakitala ndi kutentha kwa mphambano ziwiri.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 kondakitala 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.
