ʻO Constantan Copper Nickel 40 Wire / Flat Wire
Kaona Konesetanana (CuNi44Mn) Lipine Pumehana Kūʻai Kūʻē Copper Nickel
Wehewehe ʻo Constantan Wire
ʻO ke kuʻekuʻe ʻana me ke kūpaʻa haʻahaʻa a me ke koena haʻahaʻa haʻahaʻa o ke kūpaʻa ʻana me kahi pale pale / pale wela ma kahi ākea ākea ma mua o nā "manganins".CuNi44 Hōʻike ka uea Alloy i ke kūpaʻa ʻoi aku ka maikaʻi ma mua o ke kanaka. Hoʻohana ʻia i nā kaapuni ac. ʻO CuNi44 / CuNi40 / CuNi45 Constantan Copper Nickel Alloy Wire ka mea maikaʻi ʻole o ke ʻano J thermocouple me ka hao ka mea maikaʻi; Hoʻohana ʻia nā thermocouple ʻano J i nā noi mālama wela. Eia kekahi, ʻo ia ka mea ʻino o ke ʻano T thermocouple me OFHC Copper ka maikaʻi; Hoʻohana ʻia nā thermocouple type T i nā mahana cryogenic.
