Ingcaciso yeMveliso
ConstantanI-wire kunye ne-resistivity ephakathi kunye ne-coefficent yeqondo lokushisa eliphantsi lokuchasana kunye ne-flat resistance resistance / i-curve yeqondo lokushisa phezu koluhlu olubanzi kune "manganin". I-Constantan ikwabonisa ukuxhathisa okungcono kwi-corrosion kune-ganins yendoda. Usetyenziso luthande ukuthintelwa kwiisekethe ze-ac.
I-Constantan wire ikwayinto engalunganga yohlobo lwe-J thermocouple kunye ne-Iron eyona ilungileyo; 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.
