  • Double-acting electropneumatic positioner
    Patent number: 5934169
    Abstract: A double-acting electropneumatic positioner for controlling an actuator, the actuator having a first and second chamber, comprises a single-acting electropneumatic positioner which provides an output pneumatic pressure to the first chamber of the actuator. A pressure inverter, coupled to the single-acting electropneumatic positioner, inverts the output pneumatic pressure. The inverted output pneumatic pressure is then coupled to the second chamber of the actuator.
