The bench allows simple regulation of temperature, flow, level, temperature-flow and flow-rate cascade regulation and the study of hot / cold fluid control around a plate heat exchanger.

The level control can be realized with 2 types of sensor (hydrostatic or capacitive pressure).
Flow control can be performed with 2 types of actuator (control valve or variable speed pump).
The temperature regulation is carried out on a heat exchanger with the possibility of studying the delay effect.
The cascade control of temperature - flow is carried out on a tank filled with water in which a coil is immersed and water at controlled temperature circulates there
The level-flow cascade control is carried out on a column filled with water by action on a valve
The device is mounted on a welded stainless steel frame

Educational Objectives :

Identification of sensors and actuators.
Simple regulation loop wiring and cascade.
Simple regulations of 1st order.
Cascade regulation.
