Training System Level Control.
Training System Level Control Technical Description This compact teaching / training unit offers every opportunity to learn the fundamentals of process control through experimentation on a level control system. The experimentation set-up is mounted in a solid housing which also accommodates all the electronics. The transparent process tank is fed from the storage tank with the aid of a speed-controlled pump. The liquid level is measured using a pressure transducer. The transducer output signal is sent to the software controller. The controller's output signal influences the speed of the pump motor and therefore delivery flow rate. To investigate the influence of disturbance variables, an electromagnetic proportional valve in the tank outlet can be activated by the software. 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 training system and the PC is made via a USB port. The clearly structured instructional material sets out the technological fundamentals and provides a step-by-step guide through the experiments.
