  Training System Position Control

  This compact teaching / training unit offers every opportunity to learn the fundamentals of process control through experimentation on a linear position control system. The experimentation set-up is mounted on a solid housing which accommodates all the electronics. A transparent protective cover permits safe observation of the experiments. A carriage can be moved by a DC motor via a toothed belt. The linear positioning is measured by a rotary encoder and delivered as a voltage signal. The output signal from the transducer is sent to the software controller. The output signal from the controller influences the motor current. The motor is automatically shut down if the carriage reaches one of the two end positions. 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. Clearly structured and comprehensive instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.

  Training System Speed Control

  This compact teaching / training unit offers every opportunity to learn the fundamentals of process control through experimentation on a speed control system. The experimentation set-up is mounted on a solid housing which accommodates all the electronics. A transparent protective cover permits safe observation of the experiments. A DC motor drives a shaft with a mass flywheel. The dial gauge allows the speed to be read off directly at any time. The speed is measured inductively using a speed transducer. The output signal from the transducer is sent to the software controller. The output signal from the controller influences the motor current. A generator acting as a mechanical resistance to shaft rotation can be activated by the software to study 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 practice system and the PC is made via a USB port. Clearly structured and comprehensive instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.

  Training System Temperature Control

  This compact teaching / training unit offers every opportunity to learn the fundamentals of process control through experimentation on a temperature control system. The experimentation set-up is mounted on a solid housing which accommodates all the electronics. A metal bar, which is thermally insulated with cladding, is heated or cooled at one end by a Peltier element. Three temperature transducers along the axis of the bar allow the variation in temperature along the length of the bar, and hence the associated thermal lags, to be obtained for differing operating conditions. A dial-gauge thermometer offers the advantage that the temperature can be read off directly at any time. The temperature is measured using a thermal resistor (PTC). The transducer output signal is sent to the software controller. The output signal from the controller influences the operating voltage of the Peltier element and hence the heating power. A fan that dissipates part of the heating energy 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 practice 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.

  Tubular Flow Reactor

  The influence of the reaction temperature and contact time between two reactants in a chemical reaction on the resulting substance conversion can be investigated in this tubular flow reactor. The dimensions of the free-standing unit have been chosen in a way that the unit can be used in laboratories; still, the principles of industrial plants are still recognizable. Two liquid chemicals are continuously pumped through a coiled reaction tube where they react. The tube is placed in a water bath that can be heated, the reaction can take place at varying temperatures. The flow rate of the chemicals can be separately adjusted using two independent pumps. Varying the flow rate changes the time taken to pass through the tube and thus results in different periods of contact between the reactants. The product of the reaction is collected at the outlet and can be further analysed.
