EJA的差壓變送器三種常見故障

文章出處:華仁儀表 發表時間:2019-12-20 09:24

EJA差壓變送器原理: 由單晶硅諧振式傳感器上的兩上H形的振動梁分別將差壓、壓力信號轉換成頻率信號,送到脈沖計數器,再將兩頻率之差直接傳遞到CPU進行數據處理,經D/A轉換器轉換為與輸入信號相對應的4~20mADC的輸出信號,并在模擬信號上疊加一個BRAIN/HART數字信號進行通信。

EJA差壓變送器常用型號:橫河變送器、EJA210A/220A法蘭安裝式差壓變送器、EJA130A高靜壓差壓變送器、EJA120A微差壓變送器、EJA438W隔膜密封式壓力變送器、EJA118W/EJA118Y/EJA118N隔膜密封式差壓變送器、EJA440A高靜壓壓力變送器、EJA510/530A絕壓/壓力變送器故障及解決方案:測量超限造成的無顯示值;這種原因往往是由于儀表操作使用不當、儀表量程選擇不當兩個愿意造成的。
