An exemplary position regulator is disclosed which includes a regulation unit and a travel measurement system for activating an actuating drive for adjusting a control fitting to a predetermined position. A signal shaper is provided for outputting a travel signal to a superordinate device. To provide an undisturbed output of the travel signal, the signal shaper is connected in series in a transmission path between the travel measurement system and the regulation unit, and is connected in parallel with the regulation unit so as to transmit signals. The signal shaper can have a switch which is controlled by an alarm signal of the regulation unit, by which, in a first (e.g., inoperative) position, the travel measurement system is fed from the regulation unit, and, in a second (e.g., operative) position, the travel measurement system is fed from the signal shaper. The signal shaper can be automatically calibrated when the position regulator is activated, by comparing an output signal from the travel measurement system with a travel signal which is received by the regulation unit.
