It is available with either a pneumatic module for air control signals or an electro-pneumatic (I/P) module for milliamp current control signals.

How does the beta positioner work?

The Beta Positioner is a force-balanced instrument. Figure 2 shows a Beta Positioner, with either a pneumatic or electro-pneumatic (I/P) module, installed on a double-acting actuator for air-to-open action. Positioning is based on a balance of two forces; one proportional to the instrument signal and the other proportional to the stem position.
