ConstantanWaya wokhala ndi mphamvu zolimbitsa thupi komanso kutentha pang'ono kofanana ndi kukana kokhotakhota mopanda phokoso / kutentha pamapindikira ochulukirapo 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.
