style="text-indent:25px">閥門定位器是否帶CPU可分為普通電氣閥門定位器和智能電氣閥門定位器。普通電氣閥門定位器沒有CPU，因此，不具有智能，不能處理有關(guān)的智能運算。智能電氣閥門定位器帶CPU，可處理有關(guān)智能運算，例如，可進行前向通道的非線性補償?shù)?，現(xiàn)場總線電氣閥門定位器還可帶PID等功能模塊，實現(xiàn)相應(yīng)的運算。按反饋信號的檢測方法也可進行分類。例如，用機械連桿方式檢測閥位信號的閥門定位器;用霍爾效應(yīng)檢測位移的方法檢測閥桿位移的閥門定位器;用電磁感應(yīng)方法檢測閥桿位移的閥門定位器等。定位器有手動和自動之分，各自的效用也是不一樣的。深圳電器閥門定位器供應(yīng)商</p><p
