Temperature Control System

The temperature process control system includes a heated plate within a duct. Two thermocouples connect to the controller and an external meter to allow students to check and calibrate the controller input. A fan at one end of the duct blows the ambient air over the block, to change the control conditions and provide a disturbance to the system. The system allows students to adjust the heater power and the air flow rate to develop a PID based control system then adjust these parameters to achieve the required time/temperature change profile for the system in response to step changes in the system requirements.
