Qeexitaanka Constantan
Daawaha iska caabinta oo leh iska caabin dhexdhexaad ah iyo heerkul hooseeya oo ku habboon iska caabbinta iska caabbinta fidsan/ qalooca heerkulku ka ballaaran yahay "manganin". Siliga CuNi44 Alloy wuxuu sidoo kale muujinayaa iska caabin daxaleed oo ka wanaagsan kan ganniska. Isticmaalka waxay u badan tahay in lagu xaddido wareegyada ac. CuNi44/ CuNi40 /CuNi45 Constantan Copper Nickel Alloy Wire sidoo kale waa cunsurka taban ee nooca J heerkulbeegga iyadoo Birtu 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.
