Key Features:

• Demonstrates automatic control of pressure in an accumulator using proportional, proportional plus integral, and proportional, integral plus derivative (PID) control
• Uses industrial-standard parts to make it ideal for industrial, vocational and academic training
• Demonstrates operation, calibration and tuning of controllers, transmitters, converters and valves
• Compact, mobile and fully self-contained
• Connects to the TE3300/03 Flow Process Training System for cascade control
• Connects to the TE3300/06 Computer Control System for distributed control
• Safe, practical and realistic

Description:

• The Pressure Process Training System is a compact and mobile unit for a wide range of experiments in pressure control. It gives students a greater understanding of the stability of simple control systems.
• The main parts of the Pressure Process Training system are:
  • Industrial controller with auto-tune feature
  • Two-channel chart recorder
  • Current-to-pressure (IP) converter
  • Gauge pressure transmitter
  • Pneumatic control valve
  • Pressure accumulator
  • Three-speed pump
  • Reservoir
• To carry out 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. This alters the pressure in the accumulator. A pressure transmitter measures the accumulator pressure and gives feedback to the controller. For a realistic experience, the equipment has industrial-standard instrumentation and parts.
• The apparatus includes two gate valves. One valve controls the flow at the output (drain) and the other acts as a flow-bypass valve. A chart recorder shows and logs the changes of the process variable (level) and the controller output.

Learning Outcomes:

• Proportional, integral and derivative control
• Setting up and demonstrating automatic control
• The principles of loop control and the calibration and tuning of controllers, transmitters, converters and valve
• Cascade control of flow and pressure (when used with the TE3300/03 Flow Process Training System)
• Distributed control (when used with the TE3300/06 Computer Control System)
