1. Karma huila
Hana ʻia ʻo Karma alloy i ke keleawe, nickel, Aluminum a me ka hao ma ke ʻano nui. ʻO ka resistivity he 2 ~ 3 mau manawa kiʻekiʻe ma mua o MENTONG. He haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o ke kū'ē (TCR), haʻahaʻa haʻahaʻa EMF me ke keleawe, kūpaʻa maikaʻi o ke kūpaʻa no ka manawa lōʻihi a me ka ikaika anti oxidation. Kona wela hana
ʻoi aku ka laulā ma mua o MENTONG (-60 ~ 300ºC). He kūpono ia no ka hana ʻana i nā mea kūʻē pololei pololei a me ke kānana.

2. Karma nui
Uea: 0.018mm-10mm
Lipine: 0.05*0.2mm-2.0*6.0mm
Kaha: 0.5*5.0mm-5.0*250mm
Bar: 10-100mm

4. ʻO nā hiʻohiʻona ʻokoʻa o ka uea kūʻē Karma

1) E hoʻomaka ana me ka uea wela uila Nickel Chromium Class 1, ua hoʻololi mākou i kekahi o ka Ni me
Al a me nā mea ʻē aʻe, a pēlā i loaʻa ai kahi mea kūʻē pololei me ka hoʻomaikaʻi
koena wela kū'ē 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 ka uea Karmalloy KMW, - 0.03 × 10-6/ K2, a ʻo ke ʻano o ka pale wela e lilo i kahi laina pololei i loko o kahi ākea.
pae wela.

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

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

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