Constantan Tlhaloso
Resistance alloy e nang le resistivity e itekanetseng le mocheso o tlase oa ho hanyetsa o nang le khanyetso e bataletseng / mocheso oa mocheso holim'a mefuta e mengata ho feta "manganins". CuNi44 Alloy wire e boetse e bonts'a khanyetso e ntle ea kutu ho feta ea monna. Tšebeliso e atisa ho fella feela ho li-circuits tsa ac. CuNi44/ CuNi40 /CuNi45 Constantan Copper Nickel Alloy Wire hape ke ntho e mpe ea mofuta oa J thermocouple le Iron e le positive; Li-thermocouples tsa mofuta oa J li sebelisoa lits'ebetsong tsa ho phekola mocheso. Hape, ke ntho e mpe ea mofuta oa T thermocouple le OFHC Koporo e ntle; Li-thermocouples tsa mofuta oa T li sebelisoa ka mocheso oa cryogenic.
