The study bench is used to study flow control alone, level control only, level control with flow control.
Objectifs Pédagogiques :
It will be possible, for example, to achieve :
A study with a static response (level or flow).
Simple level or flow regulation
A 1st order or 2nd order regulation on the level
A level control cascade on the flow.
A delay effect
Description technique :
The bench consists of :
A feed tank, filling up with mains water by means of a hose
Auxiliary delay circuit with coil
A pallet flow meter
A float flowmeter for comparison of flow measurements on the supply
A float flowmeter for calibrated flow disturbance
A pneumatic valve.
An IP converter
Two mbar pressure sensors for level measurement, located under the two altuglas tanks
Two manual valves needle, adjustment and easy identification of the number of revolutions.
Stainless steel centrifugal pump
A master regulator
A slave regulator
Measurement and setpoint display for both controllers.
The painted steel control cabinet features:
The lockable disconnector,
The power indicator,
The emergency stop,
The 2 regulators,
A 4-position switch for the choice of: first-order level control; 2nd-order level regulation; flow regulation; cascade control.
Double-well secured terminals allow you to recover the 0-10V of the inputs and outputs of the regulators.
Control and protection of the pump.
Compound acquisition module:
- an RS485 / RS232 converter
- a Windows operating system that allows:
. Reading the PID parameters,
. The plot of the curves,
. The configuration of the remote controller
. Archiving values.
