Process station with level ,flow, pressure and temperature trainer Description and Specifications for Lab Tenders
Process station with level ,flow, pressure and temperature trainer.
The four controlled systems in the workstation can each be operated individually.
Using a corresponding controller, the level and flow rate controlled system can be set up as a cascade control system.
The design of the sensors and valve actuators allows the use of both continuous (e.g. P, I, PI, PID) and discontinuous controllers (e.g. two-point controllers) in testing.
The pumps can be controlled using either direct actuation or speed adjustment.
With the flow rate and pressure controlled systems, the manipulated variable of the controller can also be used to operate a proportional directional control valve.
A two-way ball valve with a pneumatic process actuator is installed in the return between the elevated tank and the lower reservoir. The two-way ball valve can be used to simulate a "load" for disturbance variable compensation in the level controlled system.
