TEMPERATURE PROCESS TRAINING SYSTEM

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 self-contained unit can do many experiments, but it can also connect to the optional Computer Control System (TE3300/06) for distributed control.

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 perform 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.
