Constantan Wire CuNi40 Nickel copper flat waya
Constantan Eureca Wire / Flat Waya
Mafotokozedwe Akatundu
Constantan Wire yokhala ndi mphamvu yolimbana ndi kutentha pang'ono komanso kutentha kocheperako komwe kumakhala ndi kukana kopanda / kutentha kokhotakhota mokulirapo kuposa "manganins".Constantan akuwonetsanso kukana kwa dzimbiri bwino kuposa momwe munthu amachitira.Kugwiritsiridwa ntchito kumangogwiritsidwa ntchito pa ma circuit ac.
Waya wa Constantan ndiwonso 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.
