The P...A GR feedback potentiometers are used with LM, NM, AM, and GM actuators to provide a resistive signal which varies with damper position.

The P...A GR units are applied with commercial proportional temperature controllers to provide feedback of the damper position, or with electric or electronic meters to provide position indication. The signal can also be used as a positioner for parallel operation of multiple actuators.


The P...A GR feedback potentiometers are mounted onto the direct coupled actuator. The switches are modular units that mount directly onto LM, NM, AM, and GM type actuators and are locked into place by guiding grooves on the sides of the actuator. A driver disk is attached to the actuator handle and offers direct transmission of the actuator position to the micro switch cams.
