Ingcaciso yeMveliso
I-Constantan Wire enokumelana okuphakathi kunye nokumelana okuphantsi kobushushu kunye nokumelana okuthe tyaba/ubushushu obujikeleze uluhlu olubanzi kune-"manganins". I-Constantan ikwabonisa ukumelana okungcono kokugqwala kune-man ganins. Ukusetyenziswa kudla ngokukhawulelwa kwiisekethe ze-ac.
I-Constantan wire ikwayi-negative element ye-type J thermocouple apho i-Iron iyi-positive; ii-thermocouples ze-type J zisetyenziswa kwiindlela zokunyanga ubushushu. Kwakhona, yi-negative element ye-type T thermocouple ene-OFHC Copper eyi-positive; ii-thermocouples ze-type T zisetyenziswa kumaqondo obushushu aphantsi.
