Technical Description:-

 This compact teaching / training  unit offers every opportunity to learn the fundamentals of process  control through experimentation on a pressure control system. The  experimentation set-up is mounted on a solid housing which accommodates  all the electronics. The process tank is charged with compressed airby 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 ismeasuredusing a pressure sensor. The sensor output signal  is sent to the software controller. Theoutput signal from the  controllerinfluences the speed of the diaphragm gas pump and hence the  delivery flow rate. An air consumer is simulated by way of a restrictor  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 unit and the PC is made via a USB port.
