CuNi44 Constantan Eureca Ribbon / Flat Wire
CuNi44 Lipine Eureca Constantan / Uea Flat
Ka wehewehe ʻana o Constantan
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". ʻOi aku ka maikaʻi o ke kūpaʻa corrosion 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.

Nā hiʻohiʻona huahana:
1) ʻO ka anti-oxidation maikaʻi a me ka ikaika mechanical ma ke kiʻekiʻe wela;
2) High resistivity a me haʻahaʻa wela coefficient o ke kū'ē;
3) Reelability maikaʻi loa a me ka hana ʻana;
4) maikaʻi kuʻihao performace
