The RT 451 – 455 series is constructed entirely from industrial components in order to teach control engineering in a practical manner. The use of smart sensors lays the foundations for Industry 4.0 applications. Smart sensors provide signal processing in addition to the capture of measured values thanks to integrated evaluation electronics. Besides process data, it is also possible to exchange configuration, diagnostic or statistical data. In practice this makes it faster to change over production lines, for example, or enables predictive maintenance.
The RT 453 trainer has all components required for an open and closed control loop. Two series-connected pressure vessels are available as the controlled system, which are connected to each other via a motorised valve. The air pressure is controlled in a first order (1 vessel) or a second order (2 vessels in series) controlled system. A smart pressure sensor is installed in each of the two pressure vessels as measuring elements. The pressure serves as the controlled variable. The actuator is an electropneumatic control valve with positioner, which is mounted in the supply line for the compressed air. Defined disturbance variables can be generated via valves.
The smart pressure sensors have an IO-Link interface for interference-free transfer of measured values and the exchange of configuration data.
The trainer is controlled and operated via the integrated PLC and the touch screen or via GUNT software (external PC required). The control response is displayed in the form of a time function. The network capable software makes it possible to follow and analyse the experiments at any number of workstations via a LAN/WLAN connection to the local network.
