Cov hlau no yog siv rau kev tsim cov qauv tsis kam, kev ua kom raugcov hlau xaim resistors, potentiometers, shunts thiab lwm yam hluav taws xob
thiab cov khoom siv hluav taws xob. Cov hlau tooj liab-Manganese-Nickel no muaj lub zog hluav taws xob thermal tsawg heev (emf) piv rau tooj liab, uas
ua rau nws zoo tagnrho rau kev siv hauv cov hluav taws xob circuits, tshwj xeeb tshaj yog DC, qhov twg lub thermal emf spurious yuav ua rau malfunctioning ntawm hluav taws xob
cov khoom siv. Cov khoom siv uas siv cov hlau no feem ntau ua haujlwm ntawm chav tsev kub; yog li ntawd nws cov coefficient kub qis
ntawm kev tiv thaiv yog tswj tau ntau yam ntawm 15 txog 35ºC.

Cov Lus Qhia Tshwj Xeeb
manganin hlau/CuMn12Ni2 Hlau siv hauv rheostats, resistors, shunt thiab lwm yam manganin hlau 0.08mm txog 10mm 6J13, 6J12, 6J11 6J8
Hlau manganin (cupro-manganese hlau) yog lub npe lag luam rau cov hlau sib xyaw ntawm feem ntau 86% tooj liab, 12% manganese, thiab 2-5% nickel.
Cov hlau manganin thiab ntawv ci yog siv rau hauv kev tsim khoom ntawm resistor, tshwj xeeb tshaj yog ammeter shunts, vim nws qhov kub thiab txias tsis zoo ntawm cov nqi resistance thiab kev ruaj khov ntev.

Kev siv Manganin

Cov ntawv ci thiab hlau manganin yog siv rau hauv kev tsim cov resistor, Tshwj xeeb tshaj yog ammeter shunt, vim nws qhov kub thiab txias coefficient ntawm tus nqi tsis kam thiab kev ruaj khov ntev.
Cov hlau ua los ntawm tooj liab uas tsis tshua muaj zog cua sov yog siv dav hauv cov khoom siv hluav taws xob tsawg, thermal overload relay, thiab lwm yam khoom siv hluav taws xob tsawg. Nws yog ib qho ntawm cov khoom siv tseem ceeb ntawm cov khoom siv hluav taws xob tsawg. Cov ntaub ntawv tsim tawm
