Cov ntaub ntawv tseem ceeb ntawm thermal kuj

Lub thermal resistor yog qhov siv ntau tshaj qhov ntsuas kub hauv nruab nrab mus rau qhov kub tsawg. Thermal resistance temperature ntsuas yog raws li tus yam ntxwv uas tus nqi kuj ntawm ib tug hlau conductor nce nrog rau qhov nce ntawm qhov kub thiab txias rau qhov ntsuas kub. Nws cov yam ntxwv tseem ceeb yog qhov ntsuas qhov tseeb thiab kev ua haujlwm ruaj khov. Kev ntsuas qhov tseeb ntawm platinum thermistor yog qhov siab tshaj plaws ntawm lawv. Nws tsis yog tsuas yog siv dav hauv kev ntsuas qhov kub thiab txias, tab sis kuj tau ua rau hauv cov cuab yeej siv tus qauv. Feem ntau cov thermistor yog ua los ntawm cov ntaub ntawv hlau ntshiab, nrog platinum thiab tooj liab yog feem ntau siv. Tsis tas li ntawd, cov ntaub ntawv xws li npib tsib xee, manganese, thiab rhodium tau siv los tsim cov thermistor. Muaj ntau hom kev ntsuas kub ntawm cov khoom siv feem ntau siv hauv cov thermistor hlau, nrog platinum hlau yog feem ntau siv. Ntxiv nrog rau platinum hlau, cov khoom siv thermal kuj siv rau hauv kev ntsuas kev lag luam kuj suav nrog tooj liab, npib tsib xee, hlau, hlau-nickel, thiab lwm yam.
