Uea Karma no nā mea pale pololei(0.02mm, 0.03mm, 0.04mm)

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.Loaʻa iā ia ka helu haʻahaʻa haʻahaʻa o ke kū'ē (TCR), haʻahaʻa haʻahaʻa EMF ma mua o ke keleawe, kūpaʻa maikaʻi o ke kūpaʻa no ka manawa lōʻihi a me ka anti-oxidation ikaika.ʻOi aku ka laulā o kāna hana wela 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: 0.01mm-10mm
Lipine: 0.05*0.2mm-2.0*6.0mm
Kaha: 0.5*5.0mm-5.0*250mm
3.Karma Waiwai

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 Karmalloy wire KMW, - 0.03 × 10-6/ K2,

a ʻo ka ʻaʻe wela kūʻokoʻa e hoʻohuli ʻia 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.
