Description

The Pressure Training System is a single loop pneumatic control system. It enables the study of the principles of both pressure regulation of a process and the control of flow in a pressurised system.
The System comprises a low pressure air circuit supported on a bench-mounted panel, making it suitable for individual student work or for group demonstration.

Features

• Safe low pressure operation
• Fully gauged for pressure and flow rate
• Differential and Gauge pressure sensors
• Current controlled (4-20mA) pneumatically operated control valve
• Standard industrial components
• Self-sealing outlets for manometer
• Safety valves fitted as standard
• Air used as the process fluid
