The bench has the following characteristics:
- A water circuit expansion vessel of 8 L, pump, heating device and two controlled systems with different lengths of delay
- A three-stage pump: power of 25 to 60W
- A screwed heating resistance (2000 W) with protection against the dry running and temperature limiter
- A heat exchanger air water with fan
- Three temperature measurements with Pt100 probe with length 150 mm Ø = 6 mm in several places
- A generation of disturbance variables by ball valve with calibrated scale in water circuit
- A power regulator
- A digital controller of PID type with configurable microprocessor with regulator On/Off or continuous (P, PI or PID)
- 4-20 mA analog output
- Mounting of the elements on a robust chassis in aluminum profile on multidirectional wheels with brakes
- Processes variables X and Y are accessible as analog signals via dual sink sockets
