Constantan Wire oo leh iska caabin dhexdhexaad ah iyo heerkul hooseeya oo ku habboon iska caabbinta iska caabbinta fidsan/heerkulka qalooca ka ballaaran "manganins". Constantan waxa kale oo uu muujiyaa iska caabbinta daxalka ka fiican marka loo eego ninka ganins. Isticmaalka waxay u badan tahay in lagu xaddido wareegyada ac.
Siliga Constantan sidoo kale waa walxaha taban ee nooca J thermocouple iyadoo Iron ay tahay mid togan; nooca J thermocouples waxaa loo isticmaalaa codsiyada daaweynta kulaylka. Sidoo kale, waa cunsurka taban ee nooca T thermocouple oo leh OFHC Copper togan; nooca T thermocouples waxaa loo isticmaalaa heerkulka cryogenic.
Daawaha waa non-magnetic. Waxaa loo isticmaalaa dib-u-dhaqaale koronto-dhaliyaha doorsoome iyo iska caabiyaha cadaadiska
potentiometers, fiilooyinka kululaynta, fiilooyinka kululaynta iyo dermaha. Ribbons waxaa loo isticmaalaa kululaynta bimetals. Qayb kale oo codsi ah ayaa ah soo saarida heerkulbeegyada sababtoo ah waxay soo saartaa xoog koronto oo sarreeya (EMF) iyadoo lala kaashanayo biraha kale.
