I nā kaʻina hana ʻoihana, ʻo ka mahana kekahi o nā ʻāpana koʻikoʻi e pono ke ana a mālama ʻia. I ke ana wela, hoʻohana nui ʻia nā thermocouple. Loaʻa iā lākou nā pōmaikaʻi he nui, e like me ke ʻano maʻalahi, ka hana maʻalahi, ke ana ākea, ka pololei kiʻekiʻe, ka inertia liʻiliʻi, a me ka maʻalahi o ka lawe ʻana i nā hōʻailona puka. Eia kekahi, no ka mea ʻo ka thermocouple kahi sensor passive, ʻaʻole pono ia i kahi mana waho i ka wā o ke ana ʻana, a maʻalahi loa ia e hoʻohana, no laila e hoʻohana pinepine ʻia e ana i ka mahana o ke kinoea a i ʻole ka wai i loko o nā umu a me nā paipu a me ka ʻili. ka mahana o nā mea paʻa.

Inā loaʻa nā mea hoʻokele ʻokoʻa ʻelua a i ʻole semiconductor A a me B e hana i ka loop, a ua pili nā ʻaoʻao ʻelua i kekahi i kekahi, inā ʻokoʻa nā mahana ma nā hui ʻelua, ʻo ka wela o kekahi welau ʻo T, i kapa ʻia ʻo ka ʻO ka hopena hana a i ʻole ka wela wela, a ʻo ka wela o ka ʻaoʻao ʻē aʻe ʻo T0, i kapa ʻia ʻo ka hopena manuahi (i kapa ʻia ʻo ka hopena kuhikuhi) a i ʻole ka hopena anu, e hana ʻia kahi mana electromotive i loko o ka loop, a me ke kuhikuhi a me ka nui o ka pili ka ikaika electromotive i ka mea o ka conductor a me ka mahana o nā hui ʻelua. Ua kapa ʻia kēia ʻano he "thermoelectric effect", a ʻo ka loop i haku ʻia i ʻelua conductors i kapa ʻia ʻo "thermocouple".

ʻO ka ikaika thermoelectromotive he ʻelua ʻāpana, hoʻokahi ʻāpana ka ikaika electromotive contact o ʻelua conductors, a ʻo kekahi ʻāpana ʻo ka thermoelectric electromotive force o kahi conductor hoʻokahi.

ʻO ka nui o ka ikaika thermoelectromotive i loko o ka loop thermocouple pili wale i ka mea conductor i haku i ka thermocouple a me ka mahana o nā hui ʻelua, ʻaʻohe mea pili i ke ʻano a me ka nui o ka thermocouple.
