Cov hlau ua los ntawm tooj liab uas tsis tshua muaj zog cua sov yog siv dav hauv cov hluav taws xob tsawg, thermal overload relay, thiab lwm yam

cov khoom siv hluav taws xob qis-voltage. Nws yog ib qho ntawm cov ntaub ntawv tseem ceeb ntawm cov khoom siv hluav taws xob qis-voltage. Cov ntaub ntawv tsim tawm

los ntawm peb lub tuam txhab muaj cov yam ntxwv ntawm kev ua haujlwm zoo thiab kev ruaj khov zoo dua. Peb tuaj yeem muab txhua yam

cov hlau puag ncig, cov ntaub ntawv tiaj tus thiab cov ntawv.

CuNi23Cov hlau tsis kam ua kom sov uas tsis tshua muaj zog yog siv dav hauv cov hluav taws xob tsawg, cov khoom siv thermal overload relay, thiab lwm yam khoom siv hluav taws xob tsawg

khoom siv hluav taws xob. Nws yog ib qho ntawm cov ntaub ntawv tseem ceeb ntawm cov khoom siv hluav taws xob qis-voltage. Cov ntaub ntawv tsim los ntawm peb lub tuam txhab

muaj cov yam ntxwv ntawm kev ua haujlwm zoo thiab kev ruaj khov zoo dua. Peb tuaj yeem muab txhua yam hlau puag ncig, tiaj tus thiab

cov ntaub ntawv ntawv.

Cov hlau nplaum no tsis yog hlau nplaum. Nws yog siv rau lub tshuab hluav taws xob rov ua dua qhov resistor hloov pauv thiab lub zog resistor,
potentiometers, cov xov hlau cua sov, cov xov hlau cua sov thiab cov lev. Cov ribbons yog siv rau cua sov ntawm bimetals. Lwm qhov chaw ntawm daim ntawv thov

yog kev tsim cov thermocouples vim nws tsim lub zog electromotive siab (EMF) nrog rau lwm cov hlau.

Tooj liab nickel hlau series: Constantan CuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19,CuNi23,CuNi30,

CuNi34, CuNi44.
