Kauvhluav taws xob cua sov ntsiabmuaj xws li cylindrical spirals tsim los ntawm ib los yog ob tug resistive xov hlau ntawm haum alloy nyob ntawm daim ntawv thov.
Nws cov yam ntxwv tseem ceeb suav nrog kev suav nrog cov nickel-chrome alloy hlau cua sov lub caij thiab lub zog nruj ntawm -230 V.
Cov kev siv niaj zaus yog: cov tshuab ziab khaub ncaws, cua sov, qhov cub, thiab lwm yam.
Ntxiv mus, thiab raws li cov hlau alloy lawv muaj, peb tuaj yeem paub qhov txawv peb hom qauv:

• M qauv, nrog rau 20-5 zoo thiab feem ntau yog npaj rau qhov cub.
• MS qauv, nrog 80-20 zoo thiab muaj txiaj ntsig zoo rau txhua daim ntawv thov.
• MC qauv, nrog rau 20-5 zoo thiab siv nyob rau hauv quartz thiab infrared raj.
