Constantan Wire Definition
I-resistance alloy ene-modium resistivity kunye nobushushu obuphantsi be-coefficent yokumelana kunye ne-flat resistance resistance/ubushushu begophe phezu koluhlu olubanzi kune "manganins".KuNiI-44 i-alloy wire ikwabonisa ukuxhathisa okungcono kukudleka kunee-ganins zendoda. Usetyenziso luthande ukuthintelwa kwiisekethe ze-ac. I-CuNi44/ CuNi40 /CuNi45 I-Constantan Copper Nickel Alloy Wire ikwayinto engalunganga yohlobo lwe-J thermocouple kunye ne-Iron ibe yi-positive; Uhlobo lwe-J thermocouples lusetyenziswa kwizicelo zokunyanga ubushushu. Kwakhona, yinto engalunganga yohlobo lwe-T thermocouple ene-OFHC yobhedu olulungileyo; uhlobo lwe-T thermocouples lusetyenziswa kumaqondo obushushu e-cryogenic.
