使用在煉化裝置中的智能壓力變送器，其輸出信號的經(jīng)電纜連接在DCS系統(tǒng)上，操作人員通過DCS系統(tǒng)操作站來監(jiān)控裝置現(xiàn)場壓力。在出現(xiàn)智能壓力變送器故障時，DCS操作站上會顯示測量值偏高、偏低，或出現(xiàn)測量回路IOP（- ）報警。在處理故障時，首先要判斷是現(xiàn)場儀表的故障，還是DCS系統(tǒng)的故障。如果是現(xiàn)場儀表故障，那么就需要針對儀表故障的實際情況進行多角度的分析，并且根據(jù)所使用儀表的特點，采取相應(yīng)的處理措施進行處理；如果故障檢測結(jié)果顯示是DCS系統(tǒng)的故障，就需要系統(tǒng)維護人員配合處理。</span> </p><h1> <span

style="font-size:18px;">如果壓力有脈動或振動,需要帶節(jié)流閥用以抑制脈動壓力對儀表的損傷。</span> </p> <p> <span style="font-size:18px;color:#E53333;"><strong>4.帶隔膜的場合</strong></span> </p> <p> <span style="font-size:18px;">測定腐蝕性、高黏度或溫度過高時,需要選用帶隔膜。</span> </p> <p> <span style="font-size:18px;color:#E53333;"><strong>5.防爆的必要性</strong></span> </p> <p> <span style="font-size:18px;">防爆形式分為隔爆型和本安型,長野產(chǎn)品多數(shù)為隔爆型。</span> </p> <p> <span style="font-size:18px;color:#E53333;"><strong>6.是否需要帶指示</strong></span> </p> <p> <span
