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.
Aloyiyo si maginito. Imagwiritsidwa ntchito pamagetsi osinthika a regenerator ndi resistor strain,
potentiometers, mawaya otentha, zingwe zotenthetsera ndi mphasa. Ma riboni amagwiritsidwa ntchito kutenthetsa ma bimetals. Ntchito inanso ndikupanga ma thermocouples chifukwa imapanga mphamvu yamagetsi yamagetsi (EMF) polumikizana ndi zitsulo zina.
Copper nickel alloy series: ConstantanKuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23,CuNi30, CuNi34, CuNi44.
Mulingo wa kukula:
