Hoʻolauna

I nā kaʻina hana hana ʻoihana, ʻo ka mahana kekahi o nā palena koʻikoʻi e pono ai ke ana a me ka hoʻomalu ʻia. I ke ana ʻana o ka mahana, hoʻohana nui ʻia nā thermocouples. He nui ko lākou mau pono, e like me ke ʻano maʻalahi, ka hana maʻalahi, ka laulā ana ākea, ka pololei kiʻekiʻe, ka inertia liʻiliʻi, a me ka hoʻoili mamao maʻalahi o nā hōʻailona hoʻopuka. Eia kekahi, no ka mea he sensor passive ka thermocouple, ʻaʻole pono ia i kahi lako mana waho i ka wā o ke ana ʻana, a he mea maʻalahi loa ia e hoʻohana, no laila 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 mahana o ka ʻili o nā mea paʻa.

Kumumanaʻo Hana:

Ke loaʻa nā alakaʻi ʻelua a i ʻole semiconductors ʻelua ʻano like ʻole ʻo A a me B e hana i kahi loop, a pili nā wēlau ʻelua kekahi i kekahi, inā ʻokoʻa nā mahana ma nā hui ʻelua, ʻo ka mahana o kekahi wēlau ʻo T, i kapa ʻia ʻo ka hopena hana a i ʻole ka hopena wela, a ʻo ka mahana o kekahi wēlau ʻo T0, i kapa ʻia ʻo ka hopena manuahi (i kapa ʻia hoʻi ʻo ka hopena kuhikuhi) a i ʻole ka hopena anuanu, e hoʻoulu ʻia kahi ikaika electromotive i loko o ka loop, a pili ke kuhikuhi a me ka nui o ka ikaika electromotive i ka mea o ke alakaʻi a me ka mahana o nā hui ʻelua. Ua kapa ʻia kēia hanana ʻo "ka hopena thermoelectric", a ʻo ka loop i haku ʻia me ʻelua mau alakaʻi ua kapa ʻia ʻo "thermocouple".

ʻElua ʻāpana o ka ikaika thermoelectromotive, ʻo kekahi ʻāpana ka ikaika electromotive hoʻopili o nā alakaʻi ʻelua, a ʻo kekahi ʻāpana ka ikaika electromotive thermoelectric o hoʻokahi alakaʻi.

ʻO ka nui o ka ikaika thermoelectromotive i loko o ka loop thermocouple e pili wale ana i ka mea alakaʻi e haku ana i ka thermocouple a me ka mahana o nā hui ʻelua, ʻaʻohe mea e pili ana i ke ʻano a me ka nui o ka thermocouple. Ke hoʻopaʻa ʻia nā mea electrode ʻelua o ka thermocouple, ʻo ka ikaika thermoelectromotive nā mahana hui ʻelua t a me t0. He maikaʻi ʻole ka hana.
