Hōʻike huahana

Uea manganinahoʻohana nui ʻia no ka mea kani haʻahaʻa haʻahaʻa me nā koi kiʻekiʻe loa, pono e hoʻopaʻa pono ʻia nā mea pale a ʻaʻole pono ka mahana o ka noi ma mua o +60 °C. ʻOi aku ka nui o ka wela hana ma ka lewa hiki ke hopena i kahi neʻe kūʻē i hana ʻia e ka oxidizing. No laila, hiki ke hoʻopilikia maikaʻi ʻia ka paʻa lōʻihi. ʻO ka hopena, hiki ke hoʻololi iki ka resistivity a me ka coefficient mahana o ka pale uila. Hoʻohana ʻia ia e like me ke kumu kūʻai haʻahaʻa haʻahaʻa no ka solder kālā no ke kau ʻana metala paʻakikī.

Nā noi Manganin:

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

2; Nā pahu kūʻē

3; Shunts nomea ana uila

Hoʻohana ʻia ʻo Manganin foil a me ka uea i ka hana ʻana i nā mea pale, ʻoi aku ka ammeterhūlili, ma muli o kona heluna wela ʻaneʻane ʻaʻohe o ka waiwai kūʻē a me ke kūpaʻa lōʻihi. Ua lawelawe ʻia kekahi mau pale pale Manganin ma ke ʻano he kānāwai no ka ohm ma ʻAmelika Hui Pū ʻIa mai 1901 a 1990. Hoʻohana pū ʻia ka uea Manganin ma ke ʻano he conductor uila i nā ʻōnaehana cryogenic, e hōʻemi ana i ka hoʻoili wela ma waena o nā wahi e pono ai nā pili uila.

Hoʻohana pū ʻia ʻo Manganin i nā ana no ka noiʻi ʻana i nā hawewe haʻalulu kiʻekiʻe (e like me nā mea i hana ʻia mai ka pahū ʻana o nā mea pahū) no ka mea he haʻahaʻa kona naʻau akā he kiʻekiʻe ka ʻike hydrostatic pressure.
