工作原理Operation Theory

鎧裝熱電阻是利用物質(zhì)在溫度變化時(shí)，其電阻也隨著發(fā)生變化的特征來(lái)測(cè)量溫度的。當(dāng)阻值變化時(shí)，工作儀表便顯示出阻值所對(duì)應(yīng)的溫度值。

It is based on that temperature change of material results in change of its resistance.When resistance value changes,the working instrument will display relevant temperatur
