鎧裝熱電偶溫度傳感器

鎧裝熱電偶作為溫(wen)(wen)度測量傳感器，通(tong)常(chang)與溫(wen)(wen)度變送器、調節器及(ji)顯示儀表等配套使用，組成過程控(kong)制系統，用以直接測量或控(kong)制各種(zhong)生產過程中0-1800℃范(fan)圍內的流體(ti)、蒸汽和氣體(ti)介(jie)質以及(ji)固體(ti)表面(mian)等溫(wen)(wen)度。

鎧(kai)裝熱偶(ou)(ou)電(dian)(dian)(dian)(dian)極是兩(liang)種不同成(cheng)份的導(dao)體(ti)兩(liang)端(duan)(duan)經(jing)焊(han)接，形成(cheng)回路，直接測溫(wen)端(duan)(duan)叫工作端(duan)(duan)，接線端(duan)(duan)子端(duan)(duan)叫冷端(duan)(duan)，也(ye)稱參比(bi)端(duan)(duan)。當工作端(duan)(duan)和參比(bi)端(duan)(duan)存(cun)在溫(wen)差時，就(jiu)會在回路中產(chan)生熱電(dian)(dian)(dian)(dian)流(liu)，接上顯示(shi)(shi)儀(yi)表，儀(yi)表上就(jiu)會指(zhi)示(shi)(shi)出熱電(dian)(dian)(dian)(dian)偶(ou)(ou)所產(chan)生的熱電(dian)(dian)(dian)(dian)動勢的對應溫(wen)度值。鎧(kai)裝熱電(dian)(dian)(dian)(dian)偶(ou)(ou)的熱電(dian)(dian)(dian)(dian)動勢將隨著測量(liang)端(duan)(duan)溫(wen)度升高而增長，熱電(dian)(dian)(dian)(dian)動勢的大小只和熱電(dian)(dian)(dian)(dian)偶(ou)(ou)導(dao)體(ti)材質以及兩(liang)端(duan)(duan)溫(wen)差有關，和熱電(dian)(dian)(dian)(dian)極的長度、直徑無關。鎧(kai)裝熱電(dian)(dian)(dian)(dian)偶(ou)(ou)的結構原理(li)是，是由(you)導(dao)體(ti)、高絕緣氧化鎂、外套(tao)不銹鋼(gang)保護管，經(jing)多次一體(ti)拉制而成(cheng)。鎧(kai)裝熱電(dian)(dian)(dian)(dian)偶(ou)(ou)產(chan)品主要由(you)接線盒、接線端(duan)(duan)子和鎧(kai)裝熱電(dian)(dian)(dian)(dian)偶(ou)(ou)組成(cheng)基本(ben)結構，并配(pei)以各種安裝固定裝置組成(cheng)。
