style="text-indent:25px">閥門信號反饋器采用微處理器對給定值和位置反饋作比較。如果微處理器檢測到偏差，它就用一個五步開關程序來控制壓電閥，壓電閥進而調節(jié)進入執(zhí)行機構氣室的空氣流量。當SIPART PS2 采用二線制連接時，它完全從4 至20mA給定信號中獲取電源。閥門信號反饋器采用適當?shù)陌惭b組件固定到直行程或角行程執(zhí)行機構上，執(zhí)行機構的直線或轉角位移通過安裝的組件檢測并由一個剛性連接的導電塑料電位器轉換，裝在直行程執(zhí)行機構上的組件檢測得到的角度誤差被自動地校正.微處理器根據(jù)偏差（給定值W 與位置反饋信號X）的大小和方向輸出一個電控指令給壓電閥。壓電閥將控制指令轉換為氣動位移增量，當控制偏差很大時（高速區(qū)）。閥門信號反饋器是化工生產(chǎn)中基本的設備之一。南京信號反饋器工廠</p><p style="text-indent:25px">閥門信號反饋器把切斷閥的開關狀態(tài)引入到閥位回饋器中，相當如檢測儀表的傳感器部分。南京信號反饋器工廠</p><p
