防腐液位變送器的工作原理和安裝注意事項

  防腐液位變送器適用于測量塔、罐、罐等各種容器的敞口、密封、地下儲罐的介質液位,根據檢測到的液位變化,將檢測到的液位轉換為輸出4-20 mA的標準電流信號,從而實現對液位的測量。液位ng距離監測。

  設備工作原理如下:

  防腐液位變送器主要由磁浮球、傳感器、變送器、主管和安裝法蘭五部分組成。當磁性浮球隨被檢測介質的液位變化上下浮動時,浮球中的磁性元件在傳感器的相應位置上吸收一根簧管。它會使傳感器的總電阻(或電壓)在一定程度上發生變化,然后由發送器將電阻(或電壓)的變化轉化為4-20 mma.dc的標準電流信號輸出??膳c各種顯示設備配合使用,可輸入4-20 mma.dc信號或進入計算機系統,實現液位監控。同時,二次儀表(XMT智能數顯表)可設置上下報警限值,實現液位控制或其它調節器,形成液位恒定調節系統,實現液位的連續調節。除上述功能外,UQK-2還可以直接用1.5級45C3-A型壓頭就地指示液位位置。

  (1)浮球安裝在主管上,擋板安裝在主管底部,小子格柵良好。

  (2)將主體放入容器內,固定并擰緊安裝法蘭和容器法蘭的加密墊片。

  (3)打開接線盒蓋,接入引出線,注意正負極不能接錯,蓋好盒蓋,擰緊固定的螺釘引出線,連接方式為UHC-DB型,注意事項。

  安裝防腐液位變送器時,應注意以下八點:

  1。安裝位置應遠離進氣,否則開關會因進氣波動而引起錯誤動作。

  2。如果開關安裝在混凝土池壁上,則可安裝L型角鋼支架。

  3。如果開關裝置位于混合區,則可安裝防波管或防波擋板。

  4。所選管的內徑大于浮球的內徑。

  5。建議使用8毫米多芯電纜進行布線。

  6。受控線路的負載必須與浮動開關的觸點容量匹配。

  7。被測液體的比重必須大于浮球的比重。

  8。浮動位置已根據客戶的訂單要求進行了調整。請不要隨意調整浮球的位置,以免產生偏差。
