Constantan Wire CuNi40 nickel ọla kọpa ewepụghị waya
Constantan Eureca Waya / Flat Waya
Nkọwa ngwaahịa
Constantan Waya nwere resistivity agafeghị oke na obere okpomọkụ coefficent nke nguzogide na larịị iguzogide / okpomọkụ usoro n'elu a wider nso karịa "manganins". Constantan na-egosipụtakwa nguzogide corrosion ka mma karịa nwoke ganins. A na-amachibido ojiji ya na sekit ac.
Constantan waya bụkwa ihe na-adịghị mma nke ụdị J thermocouple na Iron bụ ihe dị mma; A na-eji ụdị J thermocouples na ngwa ọgwụgwọ okpomọkụ. Ọzọkwa, ọ bụ ihe na-adịghị mma nke ụdị T thermocouple na OFHC ọla kọpa na nti; Ụdị T thermocouples na-eji okpomọkụ cryogenic.
