Pneumatic Pressure Controller
Consists of a primary element (bourdon type tube), that is connected to the process where the pressure needs to be controlled, this pressure is converted via a pneumatic-mechanic mechanism (movement equilibrium principle through a nozzle, a flapper and a feedback bellow) into a pneumatic signal. This signal is amplified in flow and pressure by a pilot that produces the output signal.
Output pressure range: 3 – 15 psi(g) or 6 – 30 psi(g).
Action easily changed between direct or reverse action.
