    壓力傳感器、變送器使用過程中應注意的事項及維護

    1.在(zai)使(shi)用(yong)過(guo)程(cheng)中(zhong)應(ying)注(zhu)意(yi)的(de)事(shi)項(xiang)。變(bian)送(song)器(qi)在(zai)工(gong)藝(yi)管(guan)道(dao)上(shang)正(zheng)確(que)的(de)安(an)裝(zhuang)位(wei)置(zhi)與(yu)被(bei)測(ce)介(jie)質(zhi)有(you)關(guan)，為(wei)獲(huo)效(xiao)得(de)最(zui)佳(jia)的(de)測(ce)量(liang)果(guo)，應(ying)注(zhu)意(yi)注(zhu)意(yi)幾(ji)點(dian)情(qing)況(kuang)。第(di)一(yi)點(dian)是(shi)防(fang)止(zhi)變(bian)送(song)器(qi)與(yu)腐(fu)蝕(shi)性(xing)或(huo)過(guo)熱(re)的(de)介(jie)質(zhi)接(jie)觸(chu)；第二點是測量液體壓力時，取壓口應開在流程管道側麵，以避免沉澱積渣；第三點是防止渣滓在導管內沉積；第四點是測量氣體壓力時
，取壓口應開在流程管道頂端

，並且變送器也應安裝在流程管道上部，以便積累的液體容易注入流程管道中；第五點是測量蒸汽或其它高溫介質時，需接加緩衝管（盤管）等冷凝器，不應使變送器的工作溫度超過極限；第六點是導壓管應安裝在溫度波動小的地方；第七點是冬季發生冰凍時，按裝在室外的變送器必需采取防凍措施，避免引壓口內的液體因結冰體積膨脹
，導至傳感器損壞；第八點是接線時，將電纜穿過防水接頭或繞性管並擰緊密封螺帽，以防雨水等通過電纜滲漏進變送器殼體內；第九點是測量液體壓力時，變送器的安裝位置應避免液體的衝擊，以免傳感器過壓損壞。
