Constantan Hlau Cuni40 Nickel Tooj Liab Ca Hlau
CONSTANTAN EURECA HLAU / pav hlau
Khoom Piav Qhia
Constantan hlau nrog kev tsav tsheb khiav tawm tsam thiab kub ua kom tsis taus nrog lub tiaj tus tiv thaiv / qhov kub nyhiab ntau dua li cov "manganins". Constantan kuj qhia tau zoo dua corrosion tsis kam tshaj tus txiv neej ganins. Siv zoo li raug txwv rau AC circuits.
Cov hlau hluav taws xob tas li tseem yog qhov tsis zoo ntawm hom j thermocouple nrog hlau ua qhov zoo; Hom J thermohoto yog siv hauv kev kho cua sov. Tsis tas li, nws yog lub ntsiab lus tsis zoo ntawm hom t Thermocouple nrog OfHC Tooj liab qhov zoo; Ntaus tlocouples yog siv ntawm cryogenic kub.
