Item Description

The temperature module is designed to enhance student study of air heating process control. By using the industrial standard PID controller, the student can gain the hand on training and experience the real time process control.

The module consist of steel frame structure, air pipe line made of mild steel, which able to operates in closed loop and open loop flow by means of switch the fresh air intake valve.  High power electric heating is incorporated in the pipe line, provides heating of air.  Air temperature sensor is incorporated in the inlet and outlet of air heater. They are feedback to temperature PID controller.

The experience is carried out by adjusting the control temperature SV to preset value, the controller would compare the process value with set value. Through PID algorithm calculation, the controller set output to control heater relay. Hence heating of air is achieved.

Student can experience different setting of P, I & D parameter effect the response of control loop. A strip recorder provides the historical record of the process change event records.
