鎧裝熱電偶溫度傳感器

鎧裝熱電偶(ou)作為(wei)溫度(du)測量傳感器，通常與溫度(du)變送器、調節(jie)器及(ji)(ji)顯示儀表(biao)等配套使用(yong)，組成(cheng)過(guo)程(cheng)控(kong)(kong)制系統，用(yong)以直接(jie)測量或控(kong)(kong)制各種生產過(guo)程(cheng)中0-1800℃范(fan)圍內的流(liu)體(ti)、蒸汽和(he)氣體(ti)介質以及(ji)(ji)固體(ti)表(biao)面等溫度(du)。

鎧裝熱(re)(re)偶(ou)(ou)電(dian)(dian)(dian)極(ji)是(shi)兩(liang)種不(bu)同成(cheng)(cheng)(cheng)份(fen)的導體兩(liang)端(duan)(duan)(duan)經(jing)焊接，形成(cheng)(cheng)(cheng)回路，直(zhi)接測溫(wen)端(duan)(duan)(duan)叫(jiao)工作端(duan)(duan)(duan)，接線端(duan)(duan)(duan)子(zi)端(duan)(duan)(duan)叫(jiao)冷端(duan)(duan)(duan)，也稱(cheng)參比端(duan)(duan)(duan)。當工作端(duan)(duan)(duan)和參比端(duan)(duan)(duan)存在溫(wen)差(cha)時(shi)，就會(hui)在回路中產生(sheng)熱(re)(re)電(dian)(dian)(dian)流(liu)，接上(shang)顯示儀(yi)表，儀(yi)表上(shang)就會(hui)指示出熱(re)(re)電(dian)(dian)(dian)偶(ou)(ou)所(suo)產生(sheng)的熱(re)(re)電(dian)(dian)(dian)動勢的對應溫(wen)度值。鎧裝熱(re)(re)電(dian)(dian)(dian)偶(ou)(ou)的熱(re)(re)電(dian)(dian)(dian)動勢將隨著測量端(duan)(duan)(duan)溫(wen)度升高而(er)增長(chang)，熱(re)(re)電(dian)(dian)(dian)動勢的大小(xiao)只(zhi)和熱(re)(re)電(dian)(dian)(dian)偶(ou)(ou)導體材(cai)質以及兩(liang)端(duan)(duan)(duan)溫(wen)差(cha)有關，和熱(re)(re)電(dian)(dian)(dian)極(ji)的長(chang)度、直(zhi)徑無關。鎧裝熱(re)(re)電(dian)(dian)(dian)偶(ou)(ou)的結構原理是(shi)，是(shi)由導體、高絕緣(yuan)氧化鎂、外套不(bu)銹鋼保護管，經(jing)多(duo)次一體拉制(zhi)而(er)成(cheng)(cheng)(cheng)。鎧裝熱(re)(re)電(dian)(dian)(dian)偶(ou)(ou)產品主要由接線盒、接線端(duan)(duan)(duan)子(zi)和鎧裝熱(re)(re)電(dian)(dian)(dian)偶(ou)(ou)組成(cheng)(cheng)(cheng)基本結構，并(bing)配以各種安裝固(gu)定(ding)裝置(zhi)組成(cheng)(cheng)(cheng)。
