Description
A self-contained mobile module for temperature process control experiments to illustrate the principles of single-loop control and the calibration & tuning of controllers, transmitters, converters and valves. Demonstrates feedback control, ON-OFF control, P/PI/PID control, distance-velocity lag and temperature control. Distributed control available when used with an optional computer control 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.
Key features:
- Shows 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
- Shows 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
