【接(jie)觸(chu)式測(ce)溫(wen)(wen)儀表(biao)】接(jie)觸(chu)式測(ce)溫(wen)(wen)儀表(biao)有哪些(xie) 接(jie)觸(chu)式測(ce)溫(wen)(wen)儀優點與(yu)使用范圍

溫度測量儀是測溫儀器類型的其中之一(yi)。根(gen)據(ju)所用測溫(wen)物質(zhi)的不同和測溫(wen)范(fan)圍的不同，有煤(mei)油溫(wen)度(du)(du)計、酒精溫(wen)度(du)(du)計、水銀溫(wen)度(du)(du)計、氣體溫(wen)度(du)(du)計、電阻(zu)溫(wen)度(du)(du)計、溫(wen)差(cha)電偶溫(wen)度(du)(du)計、輻射溫(wen)度(du)(du)計和光測溫(wen)度(du)(du)計、雙金屬溫(wen)度(du)(du)計等。

接觸式測溫儀表有哪些

溫度測量儀表(biao)按測溫方(fang)式(shi)可分為接觸(chu)式(shi)和非接觸(chu)式(shi)兩大類。

通常來說接觸式測溫(wen)儀表比較簡單(dan)、可靠，測量精度(du)較高(gao)；但(dan)因測溫(wen)元件與被測介質(zhi)需(xu)(xu)要進行充(chong)分的(de)熱交換，幫需(xu)(xu)要一定的(de)時間才能達到(dao)熱平衡(heng)，所以(yi)存在測溫(wen)的(de)延遲現象，同時受耐高(gao)溫(wen)材料的(de)限制(zhi)，不能應(ying)用于很高(gao)的(de)溫(wen)度(du)測量。

一般有膨脹式溫度(du)計(ji)、壓(ya)力(li)表式溫度(du)計(ji)、電(dian)阻式溫度(du)計(ji)、熱電(dian)偶溫度(du)計(ji)。

非接觸(chu)式儀表測(ce)溫是通過熱(re)輻(fu)射原理(li)來(lai)測(ce)量(liang)溫度的，測(ce)溫元件不(bu)需與被(bei)測(ce)介質接觸(chu)，測(ce)溫范(fan)圍(wei)廣，不(bu)受測(ce)溫上限(xian)的限(xian)制(zhi)，也不(bu)會破壞被(bei)測(ce)物(wu)體的溫度場(chang)，反應速度一般也比較快；但(dan)受到(dao)物(wu)體的發射率、測(ce)量(liang)距離、煙塵和水氣等(deng)外界因(yin)素的影響(xiang)，其測(ce)量(liang)誤差較大。
