Computerized Level Control Trainer

The Trainer provides a comprehensive experimental introduction to the fundamentals of control engineering using an example of level control.
A pump delivers water from a storage tank to the transparent level-controlled tank.  
The liquid level is measured by a pressure transducer installed at the base of the level-controlled tank.  
The controller used is a state-of-the-art digital industrial controller.  
The actuator in the control loop is a pneumatically operated control valve with an electro-pneumatic positioner.  
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.
Process control software is optionally available.
