A benchtop experimental unit that demonstrates control engineering experiments that allow learners understand and visualize different components of controlling like controllers, transducers, actuators. It contains level control with transparent tank, level measurement by pressure sensor, generation of disturbance variables by ball valve with scale in outlet, level-controlled tank with overflow and graduated scale, multi-functional digital industrial controller and control.
- Unit construction with components commonly used in industry.
- Digital controller with freely selectable parameters: P, I, D and all combinations.
- This test unit provides a comprehensive testing introduction to the fundamentals of control engineering using an example of level control.
- All components are arranged on a vertical panel, with the assistance of large-format flowcharts to enhance understanding.
- The pump delivers water from the sump into a transparent, level-controlled tank, serving as a reservoir.
- Level is measured by a pressure sensor installed at the bottom of the level control vessel.
- The controller used is the most advanced digital industrial controller.
- The control loop actuator is a solenoid proportional valve.
- A ball valve at the outlet allows the creation of definite noise variables.
- The control variable X and the modulating variable Y can be considered analog signals originating from the laboratory sockets. This enables the connection of external recording equipment, such as plotters or oscilloscopes.
