The positioner compares the electric or pneumatic input signal (4-20 mA, or 3-15psi) with the actuator’s position, generating a pneumatic output signal for proportional control actuator.
PNEUMATIC AND ELECTROPNEUMATIC POSITIONER
The positioner compares the output signal from a controller with the position feedback, and varies a pneumatic output signal to the actuator accordingly. The actuator position is therefore guaranteed for any controller output signal and the effects of varying differential pressure.
