Key Features:

• Demonstrates automatic control of temperature using proportional, proportional plus integral, and proportional, integral plus derivative (PID) control
• Uses industry-standard parts to make it ideal for industrial, vocational and academic training
• Demonstrates operation, calibration and tuning of temperature transmitters and thermocouples
• Compact, mobile and fully self-contained
• Includes delay coil to mimic realistic time lag due to a process
• Connects to the TE3300/06 Computer Control System for distributed control
• Safe, practical and realistic

Description:

• The Temperature Process Training System is a compact and mobile unit for a wide range of experiments in temperature control. It gives students a greater
  understanding of the stability of simple control systems.
• The main parts of the Temperature Process Training system are:
  • Industrial controller with autotune feature
  • Two-channel chart recorder
  • Heat-exchanger and fan
  • Temperature transmitter
  • Thermocouples
  • Delay coil
  • In-line heater
  • 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 power to the in-line heater and control the temperature of the water at any of three places. The heat-exchanger removes the heat from the water, to give quicker experiments. The thermocouples (selected by a three-way switch) give feedback to the controller. For a realistic experience, the equipment has industrial-standard instrumentation and parts.
• The apparatus includes one gate valve that works as a flow bypass. A chart recorder shows and logs the changes of the process variable (temperature) 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 temperature transmitters and thermocouples
• Operation of a temperature control system
• Distributed control (when used with the TE3300/06 Computer Control System)
