RT 030 Training System: Pressure Control, HSI Show data sheet (pdf file) Print page
Technical Description

  This compact experimental unit offers every opportunity to learn the fundamentals of control engineering through experimentation on a  pressure control system.


  The experimental set-up is mounted on a housing which accommodates all the electronics. The pressure tank is charged with compressed air by a diaphragm gas pump. The advantage of the dial-gauge manometer is that the pressure in the tank can be observed directly at any time. The pressure is measured using a pressure sensor. The sensor output signal is sent to the software controller. The output signal from the controller influences the speed of the diaphragm gas pump and hence the flow rate. An air consumer is simulated by way of a flow control valve. A solenoid valve through which air can escape can be activated by the software to investigate the influence of disturbance variables.

  The powerful state-of-the-art software is an integral part of the training system, embodying the principle of hardware/software integration (HSI). It enables the experiments to be conducted and evaluated in a user-friendly manner. The software has network capability. The link between the experimental unit and the PC is made via a USB port.

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