1. Karma alloy

Hana ʻia ka Karma alloy me ke keleawe, ka nickel, ka alumini a me ka hao ma ke ʻano he mau ʻāpana nui. ʻOi aku ka kiʻekiʻe o ka resistivity ma mua o MENTONG he 2 ~ 3 mau manawa. Loaʻa iā ia ka coefficient wela haʻahaʻa o ke kū'ē ʻana (TCR), ka EMF wela haʻahaʻa ma mua o ke keleawe, maikaʻi ke kūpaʻa no ka manawa lōʻihi a me ka anti-oxidation ikaika. ʻOi aku ka laulā o kona pae mahana hana ma mua o MENTONG (-60 ~ 300ºC). He kūpono ia no ka hana ʻana i nā mea kū'ē pololei a me ke kaumaha.

2. Ka nui o ka Karma

Uea: 0.01mm-10mm
Lipine: 0.05 * 0.2mm-2.0 * 6.0mm
Kaha: 0.5 * 5.0mm-5.0 * 250mm
3. Nā hiʻohiʻona ʻokoʻa o ke kaula kū'ē Karma

1) E hoʻomaka ana me ka uea wela uila Nickel Chromium Class 1, ua pani mākou i kekahi o nā Ni me
ʻO Al a me nā mea ʻē aʻe, a pēlā i hoʻokō ai i kahi mea kūpaʻa pololei me ka hoʻomaikaʻi ʻia
ke koina mahana kū'ē a me ka ikaika electromotive wela e kū'ē i ke keleawe.
Me ka hoʻohui ʻana o Al, ua holomua 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 mau manawa ʻoi aku ka nui.

2) He liʻiliʻi loa ke koina mahana lua β o ke kaula Karmalloy KMW, - 0.03 × 10-6/ K2,

a ʻo ke kiʻikuhi mahana kū'ē e lilo ia i kokoke i kahi laina pololei i loko o kahi ākea
pae mahana.

No laila, ua hoʻonohonoho ʻia ke koina mahana e lilo i koina mahana awelika ma waena
23 ~ 53 °C, akā ʻo 1 × 10-6/K, ʻo ke koina mahana awelika ma waena o 0 ~ 100 °C, hiki nō hoʻi
e hoʻohana ʻia no ke koina mahana.

3) He liʻiliʻi nō hoʻi ka ikaika electromotive e kūʻē i ke keleawe ma waena o 1 ~ 100 °C, ma lalo o + 2 μV/K, a

hōʻike i ke kūpaʻa maikaʻi loa no nā makahiki he nui.

4) Inā hoʻohana ʻia kēia ma ke ʻano he mea pale pololei, hana ʻia ka mālama wela haʻahaʻa
pono e hoʻopau i nā hoʻopilikia hana e like me ke ʻano o ka uea Manganin CMW.
