  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.

  Temperature Control Apparatus with Experimental Panels

  This instructional system is used to examine a simple temperature control unit. It consists of clearly arranged modular experimental panels which are suspended in a frame and connected with cables. A soldering iron equipped with a thermal element is used as the temperature control system. The temperature can be read on a digital display with a measuring transducer. The system includes a digital industrial controller which can be configured continuously as P, PD, PI and PID controller. It is possible to also use it as a two-point controller. The manipulated value can be indicated on a bar diagram. An electronic power control completes the system. The student has the opportunity to get familiar with the components of a control circuit, to interconnect them and vary their parameters. All components are of a sturdy design and therefore well suited for student experiments.

  Process Control Training Plant

  This training system for process control represents a fully functional process control system. It consists of four individual systems: process module, control console, fault simulator and service module. The actual process module contains the devices and loops for liquid-level, flow rate, temperature and pressure control with all necessary equipment, tanks and vessels, pipes and delay coils, various sensors and pneumatically actuated valves. The system is laid out in a way to represent a realistic part of a plant also found in heavy industry. The control console is equipped with four digital universal industrial controllers and four three-channel chart recorders. The controllers can configured independently as required and can be operated both individually and simultaneously. They all have serial interfaces permitting parameters to be set from a PC and facilitating interfacing with a process control system. The separate console for the fault simulation unit is used to study ten different typical system faults, e.g. sensor failure or cable break. These are activated using switches. Their effect on the system behavior of the system can then be investigated. The service module provides compressed air, hot and cold water for the process module. A process communication system facilitates the central control and monitoring of the system.

  Level Control Demonstration Unit

  This training system provides a comprehensive experimental introduction to the fundamentals of process control using an example of level control. All components are clearly laid out on a vertical panel. The large-format process diagram provides an aid to understanding. A pump transfers water from a storage tank into the transparent process tank. The level is measured by an electronic pressure transducer installed at the base of the process tank. The controller used is a state-of-the-art digital industrial controller. The actuator in the control loop is an electromagnetic proportional valve. A ball valve in the outlet enables defined disturbance variables to be generated. The controlled variable X and the manipulating variable Y can be tapped as analogue signals at lab jacks. This enables external recording equipment, such as a plotter or an oscilloscope, to be connected. An instrumentation and control software with interface module (USB) is available as an accessory. This enables the key process variables to be represented, and control functions executed. The well-structured instructional material outlines the technological fundamentals and provides a step-by-step guide through the experiments.
