工作原理
     熱電(dian)偶(ou)的電(dian)極由兩根不同導體材質組成。當測(ce)量端與(yu)參比端存在溫差時，就會產生(sheng)熱電(dian)勢(shi)，工作儀表便顯示出熱電(dian)勢(shi)所(suo)對應的溫度值。

常溫絕緣電阻
     熱電偶在環境(jing)溫度為20±15°C，相對濕度不大于80%，試驗(yan)電壓為500±50V（直流）電極與外(wai)套管之間(jian)的絕緣(yuan)電阻>1000Ω.m。

熱電(dian)(dian)偶的熱電(dian)(dian)動勢將隨著測量端溫(wen)度升高(gao)而增長(chang)，熱電(dian)(dian)動勢的的大小只和熱電(dian)(dian)偶導體材質以及兩(liang)端溫(wen)差有關，和熱電(dian)(dian)極的長(chang)度、直徑無關。裝(zhuang)配式(shi)熱電(dian)(dian)偶主要由接線(xian)盒、保護管、絕(jue)緣套管、接線(xian)端子、熱電(dian)(dian)極組成基本結(jie)構，并配以種安裝(zhuang)固定裝(zhuang)置組成。
