ʻO ka thermocouple Platinum-rhodium, nona nā pono o ke ana wela kiʻekiʻe, ke kūpaʻa maikaʻi, ka laulā o ka ana wela, ke ola lawelawe lōʻihi a pēlā aku, ua kapa ʻia hoʻi he thermocouple metala makamae wela kiʻekiʻe. Hoʻohana nui ʻia ia ma nā kahua o ka hao a me ke kila, ka metallurgy, ka petrochemical, ke aniani fiber, nā mea uila, ka mokulele a me ka aerospace.

Eia nō naʻe, he paʻakikī ke hoʻololi i nā wahi paʻakikī a me nā wahi haiki e pono ai ke kūlou ʻana a me ka manawa pane wela pōkole ma muli o kona ikaika i emi iho i nā mahana kiʻekiʻe a me kona ʻike i ka haumia o ke kaiapuni.

ʻO ka thermocouple metala makamae kahi ʻano hou o ka mea ana wela i hoʻomohala ʻia ma ke kumu o ka thermocouple metala makamae, nona nā pono o ke kū'ē ʻana i ka haʻalulu, ke kū'ē ʻana i ke kaomi kiʻekiʻe, ke kū'ē ʻana i ka corrosion kemika o ka medium, hiki ke kulou, manawa pane pōkole a me ka lōʻihi.

ʻO ka thermocouple pale kila makamae i hana nui ʻia me ka uhi metala makamae, nā mea hoʻokaʻawale, nā mea uea dipole. Hoʻopiha pinepine ʻia me ka magnesium oxide a i ʻole nā ​​mea hoʻokaʻawale ʻē aʻe ma waena o ka uhi metala makamae a me ka uea dipole, i ka hihia o ka mālama ʻana i ka insulation wela kiʻekiʻe, aia ka uea dipole i loko o kahi kūlana paʻa kinoea, i mea e pale ai i ka thermocouple mai ka pala a me ka hōʻino ʻana ma muli o ka ea a i ʻole ke kinoea wela kiʻekiʻe. (ʻo ke kiʻi hoʻonohonoho o ka uea thermocouple penei)
