Cuprothal 294/CuNi40 Alloy Resistance Wire
ʻO Constantan Wire me ke kū'ē haʻahaʻa a me ka coefficent mahana haʻahaʻa o ke kū'ē me kahi pale pale / wela wela ma kahi ākea ma mua o nā "manganins".Hōʻike pū ʻo Constantan i ka pale ʻana i ka corrosion ma mua o ke kanaka.Hoʻohana ʻia i nā kaapuni ac.
ʻO ka uea Constantan ka mea maikaʻi ʻole o ke ʻano J thermocouple me ka hao ka 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.
ʻAʻole magnetik ka alloy.Hoʻohana ʻia ia no ka resistor hoʻololi o ka uila regenerator a me ka resistor strain,
potentiometers, uwea wela, uwea wela a me ka moena.Hoʻohana ʻia nā lipine no ka hoʻomehana ʻana i nā bimetal.ʻO kahi ʻano noiʻi ʻē aʻe ʻo ka hana ʻana i nā thermocouple no ka mea e hoʻomohala ana i ka ikaika electromotive kiʻekiʻe (EMF) i hui pū me nā metala ʻē aʻe.
