Alloy 294/Cuprothal/Constantan Copper Nickel 40 Waea / Waea Papatahi mo te Whakawera
Te Wehe o Constantan (CuNi44Mn) Rīpene Whakawera Whakawera Parahi Nikeli Hiko
Constantan Waea Whakamaramatanga
Te koranu parenga me te whakareatanga ngawari me te whakarea pāmahana iti o te parenga me te anau parenga/mahana i runga i te awhe whanui atu i nga "manganins". Ko te waea CuNi44 Alloy e whakaatu ana he pai ake te aukati i te waikura atu i te tangata. Ko nga whakamahinga ka herea ki nga iahiko ac. Ko te CuNi44/ CuNi40/CuNi45 Constantan Copper Nickel Alloy Wire te mea kino o te momo J thermocouple me te rino te pai; momo J thermocouple ka whakamahia i roto i nga tono whakamaimoa wera. Ano, ko te huānga kino o te momo T thermocouple me OFHC Copper te pai; Ko te momo T thermocouple ka whakamahia ki te wera tangi.
