■ 工作原理

  概  述
  煙氣參數監測子係統可對煙氣溫度、壓力、流速、氧量、濕度等進行實時測量。煙氣參數變送器輸出4-20mA模擬信號,並由單片機進行采集,然後轉換成數字量,通過RS-485總線傳輸給數據采集儀,最遠傳輸距離可達1km。

  【性能特點】
  ◆ 4~20mA模擬和RS485數字輸出,MODBUS標準協議,符合現場數據遠傳要求。
  ◆ 數據櫃采用雙層鋼板中間夾隔熱材料的方式,具有隔熱、通風等功能。滿足避雨、雪、沙塵等現場惡劣環境的要求。
  ◆ 具有定時自動反吹功能,防止煙塵堵塞皮托管。
  ◆ 16路D/O輸出通道,滿足現場控製的需要。
  ◆ 8路A/D輸入,可擴展其它模擬量的信號采集。
  ◆ 工作電源:AC220V±10%,50Hz。
