Pressure Process Control System is a single loop pneumatic control system
which allows study of the principles of process control pressure as the process variable to be
controlled.
This Control System includes:
-
Pressure Process Rig.
-
Process Interface.
-
Process Controller.
-
Pressure Sensor Pack.
-
Digital Display Module.
-
Discovery
Software.
The Pressure Process Rig consists of a low pressure air circuit supported on a bench-mounted
panel, making it suitable for individual student work or for group demonstration.
The circuit includes:
-
Input supply filter/drier.
-
Input converter.
-
Pneumatically operated control valve.
-
2 Regulators.
-
4 Manual valves.
-
6 Gauges.
-
Sight flow meter.
-
Orifice Block with changeable Orifice Plates.
-
Differential Pressure Sensor.
-
Process Pressure Sensor.
-
27 litre Air Receiver Tank.
-
20psi Safety Relief Valve.
-
Diffusers.
