【接觸式(shi)測(ce)溫(wen)儀表】接觸式(shi)測(ce)溫(wen)儀表有哪(na)些 接觸式(shi)測(ce)溫(wen)儀優點與使用范(fan)圍

溫度測量儀是測溫儀器類型的(de)其(qi)中之一。根據(ju)所用(yong)測(ce)(ce)溫(wen)(wen)(wen)(wen)物質的(de)不同(tong)和測(ce)(ce)溫(wen)(wen)(wen)(wen)范圍的(de)不同(tong)，有煤油(you)溫(wen)(wen)(wen)(wen)度(du)計(ji)、酒(jiu)精溫(wen)(wen)(wen)(wen)度(du)計(ji)、水銀(yin)溫(wen)(wen)(wen)(wen)度(du)計(ji)、氣體溫(wen)(wen)(wen)(wen)度(du)計(ji)、電(dian)阻溫(wen)(wen)(wen)(wen)度(du)計(ji)、溫(wen)(wen)(wen)(wen)差電(dian)偶(ou)溫(wen)(wen)(wen)(wen)度(du)計(ji)、輻射溫(wen)(wen)(wen)(wen)度(du)計(ji)和光測(ce)(ce)溫(wen)(wen)(wen)(wen)度(du)計(ji)、雙金屬溫(wen)(wen)(wen)(wen)度(du)計(ji)等(deng)。

接觸式測溫儀表有哪些

溫度測量儀表按測溫方式可分為接(jie)觸(chu)式和非(fei)接(jie)觸(chu)式兩大類(lei)。

通常來(lai)說接觸式(shi)測(ce)溫儀表(biao)比較簡單、可靠，測(ce)量精度較高(gao)；但因測(ce)溫元件與被(bei)測(ce)介質需要進行(xing)充分的熱交換，幫需要一定的時間才能達(da)到熱平衡，所以存在測(ce)溫的延遲現象(xiang)，同(tong)時受耐(nai)高(gao)溫材料的限制，不能應(ying)用于(yu)很高(gao)的溫度測(ce)量。

一般有膨脹(zhang)式溫度計、壓力表式溫度計、電(dian)(dian)阻式溫度計、熱電(dian)(dian)偶溫度計。

非接(jie)觸式儀表測溫(wen)(wen)是通過(guo)熱輻射原理來測量(liang)(liang)溫(wen)(wen)度(du)的(de)(de)，測溫(wen)(wen)元件不(bu)(bu)需與被(bei)(bei)測介(jie)質接(jie)觸，測溫(wen)(wen)范圍(wei)廣，不(bu)(bu)受(shou)測溫(wen)(wen)上限的(de)(de)限制(zhi)，也不(bu)(bu)會破壞被(bei)(bei)測物體的(de)(de)溫(wen)(wen)度(du)場，反應(ying)速(su)度(du)一(yi)般也比較快；但受(shou)到(dao)物體的(de)(de)發射率(lv)、測量(liang)(liang)距離(li)、煙塵和水(shui)氣(qi)等(deng)外界因素的(de)(de)影響，其測量(liang)(liang)誤差較大(da)。
