A Pt100 temperature probe measure water contained in vat. This one include all security devices as overflow draining, a low level security alarm. The electric heater immersed in the vat is equipped with a security thermostat controled by a PID conroller. The vat is stirred. The controller also control an electro valve which inject cold water to create a disturbance.


Teaching objectives

- Study of temperature control with two different actuators (1st range process)
- Split range control
- Study of a static answer
- Identification in open and closed loop mode
- Measure of the output power of the regulator on the control cabinet with the help of secured plugs
- Disturbance of the set point.
