Electro-pneumatic system for controlling a double-acting pneumatic actuator

摘要

The electro-pneumatic system (1) has a separating electronic (5) that is connected upstream in pneumatic pre-controlling stage for opposite separation of electronic controlling signals (U-y) around an electronic controlling unit value (cp) in two electrical reflection signals. The electronic controlling signals are received by the electro-pneumatic system or generated by an electronic regulator (3) of the electro-pneumatic system. Independent claims are included for the following: (1) an arrangement of electro-pneumatic system; and (2) a method for amplifying an electro-pneumatic system.
