The most common form of accomplishing pneumatically driven motion is by applying or removing air pressure to extend or retract a cylinder, but there are also rotary actuators and even air motors. All of these devices can be automated using digital controllers integrated to command the pneumatics and make the equipment move as desired. This motion is often simply a discrete on-or-off mode, as opposed to a continuously variable analog mode, but that’s not always the case. Linear actuators can be configured for multiple intermediate stops, or with modulating options for variable positioning. For process control valves, pneumatic valve positioners can perform this function, and they often need to be monitored to ensure accurate activation. Many users find that they can take full advantage of the benefits offered by pneumatic fluid pow...
