4 Variable process control trainer

The unit is autonomous, composed of two tanks and two pumps for running in closed circuit.

It allows to study and set several control loop simple or in cascade.

It includes :

– Water flow rate control by action on a valve

– Water level control by action on a valve

– Discharge pressure control by action on the pump’s variator

– Water level control by action on the pump’s variator

– Bath temperature control by action on an electrical heater

– Flow / level cascade control by action on a valve

Two control loops can function on the same time.

 

The components installed are industrial one allowing a technologic study with the help of the technical documents in the technical file.

A tactile screen display the measures, control parameters setting, the functioning mode auto/manu, the data recording on a USB stick.
