ConstantanaUea me ke kuʻekuʻe haʻahaʻa a me ka coefficent mahana haʻahaʻa o ke kūpaʻa me ka pale pale / ka wela wela ma kahi ākea 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.
