  Trainer For Industrial Controllers

  This trainer familiarises students with the operation and function of a state-of-the-art industrial process controller. The controller has freely accessible inputs and outputs. Defined input levels and step signals can be produced with a signal generator. A digital voltmeter is used to measure the input and output signals. A simple first order lag is simulated to allow the response and stability of a closed control loop to be investigated. All signals are accessible via lab jacks so a standard x/y plotter or line recorder can be used. It is also possible to control external system models with this controller. As well as manual configuration and parameter setting with keys, the controller can be configured (configuration software supplied) from a PC over an RS232 interface. Clearly structured instructional material sets out the fundamentals and provides a step-by-step guide through the exercises.

  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.

  PH – Value Control Trainer

  This teaching and training system provides a comprehensive experimental introduction to the fundamentals of process control using an example of temperature control. A circulating pump transfers water within a closed circuit. The flow of water can be regulated by a hand-operated valve. The loop also contains a screw-in heater, a heat exchanger with fan, and three integrated thermocouples for temperature measurement. Dead times can be represented by the use of different lengths of process delay. A thyristor power controller is used as the actuator. The controller used is a state-of-the-art digital industrial controller. It can be configured as a continuous or a switching device, and can activate the heater via the actuator and / or the fan. 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. A process control software is optionally available. The software permits the construction of a complete networked system comprising multiple trainers from the series. The key process variables can also be represented, and control functions executed.

  Nutsche Pressure Filter

  Nutsche Filters are used for discontinuous cake filtration of suspensions with high solid concentrations. The suspension production unit produces a suspension of diatomite and water and delivers it from above into the Nutsche Filter. In the bottom flange of the Nutsche Filter is a recessed sieve base with a filter cloth. A growing filter cake accumulates on the filter cloth made from the separated solid material. The applied pressure in the top section of the Nutsche Filter pushes the filtrate through the filter cake and the filter cloth. It is collected in the bottom section of the tank. After filtering, the filter cake obtained is washed with a washing liquid (water) and is then dried by an air stream.
