Cov hlau no yog siv rau kev tsim cov qauv tsis kam, cov hlau xaim hluav taws xob uas muaj zog, cov potentiometers, shunts thiab lwm yam khoom siv 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, tshwj xeeb tshaj yogDC, qhov twg qhov thermal emf cuav yuav ua rau tsis ua haujlwm ntawm cov khoom siv 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 tooj liab-basedtsis kamCov hlau ua kom sov yog siv dav hauv cov khoom siv hluav taws xob tsawg, cov khoom siv 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 khoom siv uas peb lub tuam txhab tsim tawm muaj cov yam ntxwv ntawm kev tiv taus zoo thiab ruaj khov. Peb tuaj yeem muab txhua yam hlau puag ncig, tiaj tus thiab cov ntaub ntawv ntawv.
