Product Code:
SCI-EDU790002
Description:
Computerized Flow Control Trainer
Specification:
The Trainer provides a comprehensive experimental introduction to the
fundamentals of control engineering using an example of flow control.
A pump delivers water from a storage tank through a piping system.
The flow rate is measured by an electromagnetic sensor, which permits
further processing of the measured value by outputting a standardized
current signal.
A Rota meter indicates the flow rate.
The controller used is a state-of-the-art digital industrial controller.
The actuator in the control loop is a control valve with electric motor
operation.
A ball valve in the outlet line enables defined disturbance variables to
be generated.
The controlled variable X and the manipulating variable Y are plotted
directly on an integrated 2-channel line recorder.
Alternatively, the variables can be tapped as analogue signals at lab
jacks on the switch cabinet.
This enables external recording equipment, such as an oscilloscope or a
flatbed plotter, to be connected.
