style="text-indent:25px">閥門信號反饋器按閥門反饋器輸出和輸入信號的增益符號分為正作用閥門反饋器和反作用閥門反饋器。正作用閥門反饋器的輸入信號增加時，輸出信號也增加，因此，增益為正。反作用閥門反饋器的輸入信號增加時，輸出信號減小，因此，增益為負(fù)。按閥門信號反饋器是否帶CPU可分為普通電氣閥門反饋器和智能電氣閥門信號反饋器。普通電氣閥門信號反饋器沒有CPU，因此，不具有智能，不能處理有關(guān)的智能運(yùn)算。智能電氣閥門信號反饋器帶CPU，可處理有關(guān)智能運(yùn)算，例如，可進(jìn)行前算。個調(diào)節(jié)器控制兩個執(zhí)行器實(shí)行分程控制時，可用兩個信號反饋器，分別接受低輸入信號和高輸入信號，則一個執(zhí)行器低程動作，另一個高程動作，即構(gòu)成了分程調(diào)節(jié)。</p><p
