RT 614 Level Control Demonstration Unit Show data sheet (pdf file) Print page
Technical Description

  This experimental unit provides a comprehensive experimental introduction to the fundamentals of control engineering using an example of level control.

  All components are clearly laid out on a vertical panel. The large-format process schematic provides an aid to understanding. A pump delivers water from a storage tank into the transparent level-controlled tank. The level is measured by a pressure sensor 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 an electromagnetic proportional valve. A ball valve in the outlet enables defined disturbance variables to be generated. The controlled variable X and the manipulating variable Y can be tapped as analogue signals at lab jacks. This enables external recording equipment, such as a plotter or an oscilloscope, to be connected.

  An instrumentation and control software (RT 650.40) with interface module (USB) is available as an accessory. This enables the key process variables to be represented, and control functions executed.

 

  The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
