Constantan Wire CuNi40 Nickel copper flat waya
Constantan Eureca Wire / Flat Waya
Mafotokozedwe Akatundu
Constantan Wire yokhala ndi mphamvu zodziletsa komanso kutentha kochepa kofanana ndi kukana komwe kumakhala kopingasa / kutentha kopindika pamitundu yotakata kuposa "manganins". Constantan akuwonetsanso kukana kwa dzimbiri bwino kuposa momwe munthu amachitira. Kugwiritsiridwa ntchito kumangogwiritsidwa ntchito pa ma circuit ac.
Waya wa Constantan ndiyenso chinthu choyipa cha mtundu wa J thermocouple ndi Iron kukhala yabwino; mtundu J thermocouples amagwiritsidwa ntchito pochiza kutentha. Komanso, ndi chinthu choyipa cha mtundu wa T thermocouple wokhala ndi OFHC Copper zabwino; mtundu wa T thermocouples amagwiritsidwa ntchito pa kutentha kwa cryogenic.
