Sharaxaada Alaabta
ConstantanSilig leh iska caabin dhexdhexaad ah iyo heerkul hooseeya oo isku habboon iska caabbinta leh caabbinta fidsan/heerkulku ka badan yahay baaxadda "manganin". 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.
