KarmaUea kū'ē no ka Resistor a me nā mea hoʻomehana

Mea Kemika: Cr 19~21.5%, Ni: Kaulike, Al 2.5~3.2%, Fe 2.5~20%

Kū'ē: 1.33 ohm mm2/m

Ke kū'ē ʻana he 800 Ohms no kēlā me kēia kapuaʻi Mil Pōʻai ma 20° C (68° F)
Kaumaha no kēlā me kēia ʻīniha kupika =. 293 paona.

Ka Umekaumaha Kūikawā 8.10

Anawaena 0.025mm~5mm

Hoʻohana: kū'ē

Nā hiʻohiʻona ʻokoʻa o ke kaula pale 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.

Hana pū mākou i nā ʻano uea kū'ē ʻē aʻe e like me NiCr 80/20, NiCr 70/30, Nicr 60/15, Cr25Al5, a pēlā aku.
