manganese tsis kam hlau rau cov khoom siv hluav taws xob thiab hluav taws xob

Kev Piav Qhia Luv:

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 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 Cim Npe Khoom

Hlau manganinyog ib qho hlau tooj liab-manganese-nickel (CuMnNi alloy) rau kev siv ntawm chav tsev kub. Cov hlau no yog tus cwj pwm los ntawm lub zog thermal electromotive qis heev (emf) piv rau tooj liab.
Cov hlau manganin feem ntau 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 hluav taws xob.
