Uea Alloy Thermocouple ʻAno K Kiʻekiʻe 0.5mm KP KN Wire

ʻO ke kaula Thermocouple e hiki ai ke ana ʻia nā mahana ma ke ʻano uila. ʻO kahi kūkulu thermocouple maʻamau he mau metala like ʻole i hui pū ʻia me ka uila ma kahi ʻike a hoʻopili ʻia i kahi mea ana voltage ma kekahi ʻaoʻao. Ke wela kekahi hui ma mua o kekahi, hana ʻia kahi ikaika "electromotive" thermal (ma millivolts) e pili pono ana i ka ʻokoʻa o ka mahana ma waena o nā hui wela a me ke anu.

NiCr-NiSi (ʻAno K)uea thermocoupleloaʻa ka hoʻohana ākea loa i nā thermocouple metala kumu āpau, ma ka mahana ma luna o 500 °C.
ʻOi aku ka ikaika o ke kūpaʻa o ka uea thermocouple ʻano K i ka oxidation ma mua o nā thermocouple metala kumu ʻē aʻe. Loaʻa iā ia ka EMF kiʻekiʻe e kūʻē i ka Platinum 67, pololei maikaʻi loa o ka mahana, ʻike a me ke kūpaʻa, me ke kumukūʻai haʻahaʻa. Manaʻo ʻia no ka oxidizing a i ʻole nā ​​​​lewa inert, akā ʻaʻole hiki ke hoʻohana pololei ʻia i nā hihia aʻe:
(1) ʻOkoʻa ka oxidizing a me ka hoʻemi ʻana i ka lewa.
(2) Lewa me nā kinoea sulfur.
(3) Lōʻihi ka manawa ma ka hakahaka.
(4) ʻO ka lewa oxidizing haʻahaʻa e like me ka hydrogen a me ke kalapona monoxide.
