Ib daim ntawv khoom tsim los ntawm kev sib txuas ua ke thiab dov ob lossis ntau txheej ntawm cov hlau nrog sib txawv coefficients ntawm thermal expansion.
Thermostatic bimetal yog cov ntaub ntawv uas tsim los ntawm kev sib txuas ua ke thiab dov ob lossis ntau txheej ntawm cov hlau nrog sib txawv coefficients ntawm thermal expansion; Nws feem ntau yog siv rau hauv cov khoom siv xws li ntsuas kub, ntsuas kub, tswj tsis siv neeg, hloov mus txawv tebchaws, thiab lub sijhawm relay- ncua sijhawm tswj.
Cov khoom no muaj cov yam ntxwv ntawm kev khoov hauv kev teb rau qhov kub thiab txias hloov, tso cai rau nws los tsim rau hauv cov khoom siv rau qhov kub thiab txias - qhia thiab tsis siv neeg tswj cov twj paj nruag; muaj cov duab muaj xws li lub voj voog, duab plaub, kiv cua-puab, thiab daim ntawv kauv.
