This bench allows the study of pH regulation in a container by acting on the injection speed (basic or acidic liquid) of the pump through a regulator. Different algorithms can be studied.
Educational Objectives :
Establishment of a regulation loop Measure / Actuator / Regulator,
Study in enslavement and regulation,
Influence of the regulation algorithm by the return to a given instruction following a perturbation.
Technical specifications :
A container of capacity 5 liters,
A variable speed magnetic stirrer,
A pH probe
Digital controller, RS485 communication board, measurement / reference display / PID control parameters,
P, I or PID algorithm
A variable flow peristaltic pump
1 acid storage container,
Analog control by acting on the motor control of the peristaltic pump
Basic injection disruption.
The cabinet can be connected to a recorder for the recovery of regulator power output and measurement
Stainless steel frame, to ask
Option 1: Acquisition
