Actuators are key components of process engineering systems. They create a link between the controller and the system. Optimum control loop design depends on a sound knowledge of actuator behaviour as well as knowledge of the controlled system response.

Nowadays most industrial processes are automated. Process controllers are at the heart of the automation of process applications. State-of-the-art digital process controllers offer a level of functionality which would have been inconceivable some years ago. Alongside extensive configuration and parameter setting functions to adapt to the control task, they also permit interconnected networking. Thus, process automation by way of centralised process control systems or distributed control systems (DCS) is possible. This range of equipment provides a step-by-step introduction to process automation and process control engineering based on process controllers and field bus systems.

Modular calibration systems

Every component of a control loop exhibits a complex behaviour. This behaviour significantly influences the quality of the control process. It is therefore necessary to calibrate the key components of a control loop.

Simple process engineering control systems

Systems in which only one variable is controlled are ideally suited to introduce students to the subject matter. Much emphasis was placed on the use of industrial components in the development of these control systems. This enhances the practical relevance and industrial applicability of these systems. These are simple control loops. The components can be easily identified visually and assigned to their respective functions.

Fuzzy control

Fuzzy methods and microcontrollers have gained greatly in importance in automation over recent years. Fuzzy methods are particularly suitable for systems that mathematics cannot describe adequately or easily. These include, in particular, multivariable systems, and non-linear or time-variant systems.

A PLC (programmable logic controller) is essentially a computer adapted to the needs of industry. Its inputs and outputs are not designed for humans, but for use in the control of machines. Machine and operator interact solely by way of limit switches, momentary-contact switches or photoelectric switches.

Coupled multivariable systems

Normally, multiple variables need to be controlled at the same time in industrial production processes. Our devices therefore enable students to learn and understand the complex interrelations of a multivariable control process in a practical manner. Again, we of course only use real, industrial components to ensure a high practical relevance.
