The main parts of the Pressure Process Training system are:

• Reservoir.
• Three-speed pump.
• Industrial controller with auto-tune.
• Pneumatic control valve.
• Pressure accumulator.
• Two-channel chart recorder.
• Current-to-pressure (IP) converter.
• Gauge pressure transmitter.
• This alters the pressure in the accumulator. 
• To perform experiments, students fill the reservoir with clean water and prime the system. 
• They then set the controller to regulate the flow of water using a pneumatic valve. 
• A pressure transmitter measures the accumulator pressure and gives feedback to the controller.
