Hōʻike huahana
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.
