ABSTRACT:
An electropneumatic position regulator having a current/pressure transducer has, as electric input, at least one coil (11) fed with a current (setting signal), as well as a permanent magnet (16) whose relative position is variable as a function of the current for the adjustment of a nozzle/impact-plate arrangement (17, 18) of a pneumatic system. The position regulator serves for a pneumatic setting device (23) which has a stroke output and is connected with the nozzle/impact-plate arrangement. The position regulator furthermore comprises a position report device with an electric path transmitter (31) which is connected to the stroke output (32) of the setting device (23). The report signal from the electric path transmitter (31) is fed back to the electric input (coil 12) of the current/pressure transducer.
