The experimental device consists of a pressure measurement on the analog sensor line, a centrifugal pump looping on a tank of 50 liters through a proportional pneumatic valve for regulating the water flow controlled by the regulator. A bypass circuit can cause a flow leak that the regulator will compensate by changing the opening of the valve to maintain the pressure in the circuit.




Educational Objectives :
  • Pressure regulation (1st order process)
  • Study of the static response
  • Open loop and closed loop identification
  • Reproducible disturbances of the set quantity
  • Recovery of the measurement and the power output of the regulator on the front of the box by secure plugs
Technical specifications :
  • A launching tank
  • Stainless steel centrifugal pump
  • Proportional pneumatic valve
  • A P / I converter
  • A pressure sensor, 4-20 mA output
  • A manometer
  • A float flowmeter
  • A set of manually operated valves
  • A pressure disrupter circuit
  • A digital regulator
  • Universal input: TC, Pt100, mA, mV, V, Hz
  • 4-20 mA control output
  • Triple display output / setpoint
  • Regulatory algorithm: P, PI, PID, self-adaptive
  • RS485 communication card
Options :
Acquisition module
This module is composed of:
- RS485 / RS232 converter for PC acquisition
- Windows operating software for reading PID parameters, drawing of curves, configuration of the remote controller and archiving of values.
