R/T參數(shù)解讀
RT表即為平常所說的NTC熱敏電阻溫度傳感器RT關(guān)系表,主要反映NTC在不同溫度所對應(yīng)的不同電阻值,其正確的參數(shù)在軟件開發(fā)中有非常重要的作用。標(biāo)準(zhǔn)的RT表一般包括幾個主要參數(shù):①103指@25℃時的標(biāo)稱阻值;②3475代表B值;③F代表熱敏電阻精度為±1%
本表為10K±1% B值3470 NTC R/T表,標(biāo)稱阻值在25℃時為10kΩ,B值為3470k,允許偏差精度為±1%,詳細(xì)參數(shù)見下表。
-----------------------------
標(biāo)稱阻值:10k kΩ @25℃;公差精度: + / -1%
B值 :3470K@25/50℃;B值精度:+ / - 1%
