Pneumatic technology uses pressured gas to drive some sort of mechanical motion. The most common gas used in pneumatic technology is dry air. The air must be dry as moisture has different compressive qualities. Pneumatic technology is very similar to hydraulic technology, however the fluid used to drive the motion here is always a liquid.
Pneumatic systems are operated using a central pneumatic device (such as an air motor or compressor) and utilise manual or automatic solenoid valves to control the airflow around the system.
Pneumatic systems contain many components, pneumatic pressure indicator function fittings being one example.
Pneumatic pressure indicator function fittings are visual indicators installed into pneumatic systems. They visually show the user that the pneumatic control system is operating at the correct pressure.
Pneumatic pressure indicator function fittings come in a variety of sizes, pressure settings and materials so the correct specification can be selected for the system.
