Study the automated command and control systems associated with hydraulic and technical installations (pump speed variation, level measurement, basin emptying, basin agitation)

Identify sensors, actuators, process to control
Write a GRAFCET.
Calibrate an analog sensor and study its linearity,
The system consists of a stirred mixing tank fed by two bins. Each bin has an electric drain valve and a manual drain valve and a low level sensor. The mixing tank also has a high level sensor.

The bench consists of :

  • Three 5 liter PVC tanks with emptying,
  • Three electric solenoid valves,
  • Four capacitive level sensors,
  • An agitator (motor and propeller).
  • A pH control loop managed by the PID function of the PLC. She is made of :
  • A pH measuring probe,
  • A pH / I transmitter (4-20 mA),
  • A 110V peristaltic pump, the speed of the motor is managed by a Eurotherm variator
  • A feed tray for the acid or base,
  • A 600x400x250 painted steel cabinet with :

    - 1 padlockable switch,
    - 1 emergency stop,
    - 1 reset button,
    - 1 power on indicator,
    - 1 start and 1 stop button,
    - 4 switches,
    - PLC wiring terminals,
    - Control and the agitator protection,
    - 1 transformer
    - 24V relay and solenoid valve,
    - 1 contactor,
    - 1 continuous 24V supply for the PLC.
