Wehewehe Huahana

Uea manganinhoʻohana nui ʻia no nā mea hana uila haʻahaʻa me nā koi kiʻekiʻe loa, pono e hoʻopaʻa pono ʻia nā resistors a ʻaʻole pono e ʻoi aku ka mahana o ka noi ma mua o +60 °C. ʻO ka ʻoi aku ma mua o ka mahana hana kiʻekiʻe loa i ka lewa e hopena i kahi drift resistance i hana ʻia e ka oxidizing. No laila, hiki ke hoʻopilikia maikaʻi ʻole ʻia ke kūpaʻa lōʻihi. ʻO ka hopena, hiki ke loli iki ka resistivity a me ke coefficient mahana o ke kū'ē uila. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea pani haʻahaʻa no ka solder kālā no ke kau ʻana i ka metala paʻakikī.

Nā noi ʻana o Manganin:

1; Hoʻohana ʻia no ka hana ʻana i ke kūpaʻa pololei o ka ʻeha uea

2; Nā pahu kū'ē

3; Nā Shunts no nā mea ana uila

Hoʻohana ʻia ka pepa kini a me ka uea Manganin i ka hana ʻana i nā resistors, ʻoiai nā shunts ammeter, ma muli o kona coefficient mahana ʻole o ka waiwai kū'ē a me ke kūpaʻa lōʻihi. Ua lawelawe kekahi mau resistors Manganin ma ke ʻano he kūlana kānāwai no ka ohm ma ʻAmelika Hui Pū ʻIa mai 1901 a 1990. Hoʻohana ʻia hoʻi ka uea Manganin ma ke ʻano he alakaʻi uila i nā ʻōnaehana cryogenic, e hoʻemi ana i ka hoʻoili wela ma waena o nā wahi e pono ai nā pilina uila.

Hoʻohana ʻia ʻo Manganin i nā ana no nā haʻawina o nā nalu haʻalulu kiʻekiʻe (e like me nā mea i hana ʻia mai ka pahū ʻana o nā mea pahū) no ka mea he haʻahaʻa kona ʻike koʻikoʻi akā he kiʻekiʻe kona ʻike kaomi hydrostatic.
