  Multi-Process Control Trainer

  This control trainer is a comprehensive unit featuring only industrial components. It contains a transparent tank for liquid-level and pressure control, a corresponding pipe for flow control, and a two-circuit system with a plate heat exchanger for temperature control. Alternatively, a pneumatically operated control valve or a speed-controlled pump are used as actuator. The parameters of the digital controller can be adjusted over wide ranges so that a large number of different process conditions can be investigated. Electronic sensors measure the individual process values. A three-channel recorder with current inputs is included for recording the control behavior over time. Software for the process visualization and Profibus card are available as an accessory.

  Training System Level Control

  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.

  Process Control Rig

  The unit is used as an introduction to the subject of control technology. Temperature, flow rate and filling level control systems are used as examples to provide clear and practical fundamental information. The experimental system is controlled from the PC screen (not included in scope of supply). The supplied process control and illustration programs make it possible to carry out the experiment as well as record measurement reports and store measured data. Important process variables are shown digitally on the unit itself. All components of the unit are clearly mounted on a metal sheet. The storage and process tanks are transparent for better viewing of the process. The unit is designed as a experimental unit for tabletop use. It requires only an electrical power connection for operation.

  Pressure Control Trainer

  This teaching and training system provides a comprehensive experimental introduction to the fundamentals of process control using an example of pressure control. The air pressure control system is a 2nd order system. It comprises two in-line pressure vessels interconnected by a restrictor valve. An additional valve on the second tank makes air tapping possible and so can be used to simulate a disturbance variable. A pressure transducer mesaures the pressure in the second vessel. The controller used is a state-of-the-art digital industrial controller. The actuator in the loop is a pneumatically operated control valve with a standardised current signal input. The controlled variable X and the manipulating variable Y are plotted directly on an integrated 2-channel line recorder. Alternatively, the variables can be tapped as analogue signals at lab jacks on the switch cabinet. This enables external recording equipment, such as an oscilloscope or a flatbed plotter, to be connected.
