4. Nā hiʻohiʻona ʻokoʻa o ka uea kūʻē Karma

1) E hoʻomaka ana me ka Nickel Chromium uea wela uila Class 1, ua hoʻololi mākou i kekahi o ka Ni me Al a me nā mea ʻē aʻe, a no laila ua loaʻa i kahi mea kūpaʻa pololei me ka hoʻomaikaʻi ʻana i ka coefficient mahana kūʻē a me ka ikaika electromotive wela i ke keleawe.
Me ka hoʻohui ʻana o Al, ua lanakila mākou i ka hana ʻana i ka resistivity volume 1.2 mau manawa ʻoi aku ka nui
ma mua o ka uea wela uila Nickel Chromium Class 1 a me ka ikaika tensile 1.3 manawa ʻoi aku ka nui.

2) He liʻiliʻi loa ka helu lua wela β o Karmalloy wire KMW, - 0.03 × 10-6/ K2,

a ʻo ke ʻano o ka pale wela e hoʻololi i kahi laina pololei i loko o kahi ākea ākea.

No laila, ua hoʻonohonoho ʻia ka coefficient wela i ka awelika wela ma waena o 23 ~ 53 °C, akā 1 × 10-6/K, ʻo ka awelika wela coefficient ma waena o 0 ~ 100 °C, hiki nō hoʻi.
e aponoia no ke koena wela.

3) ʻO ka ikaika electromotive e kū'ē i ke keleawe ma waena o 1 ~ 100 °C he mea liʻiliʻi hoʻi, ma lalo o + 2 μV / K, a hōʻike i ke kūpaʻa maikaʻi loa i nā makahiki he nui.

4) Inā e hoʻohana ʻia kēia ma ke ʻano he mea kūʻē pololei, pono ka mālama ʻana i ka wela haʻahaʻa e hoʻopau i nā distortions e like me ka hihia o Manganin wire CMW.
