ABB AV Electro-Pneumatic Positioner
Categories:
A mechanical connection from the actuator to a position feedback cam in the positioner establishes actual position. Three characterized segments on one cam provide application flexibility by establishing various relationships between input signal and actuator position. The relationships provided by the segments are square root, linear, and square.
The Type AV1 positioner receives an external pneumatic signal and converts it to a pneumatic output. This output produces the motive force that positions the power actuator.
The type AV2 positioner receives an external 4-20mA signal and converts it to a pneumatic output. This output produces the motive force that positions the power actuator
- Characterized cam operation
- Easy adjustment and calibration
