The Essentials of Process Control (EPC) range of products takes students through the fundamentals and principles of process control and progresses to give them a thorough grounding in the control of physical processes. Four independent process units demonstrate level, flow, temperature and pressure as the controlled variable.
The effect of making changes to the system or to the controller configuration can be quickly investigated by applying repeatable disturbances or step changes to the process. The concepts of closed loop control, including on/off control, proportional control, proportional/integral and proportional/integral/derivative (PID) control can be explored and demonstrated. Some units also cover both time proportioning and analogue control of the same parameter. Comparison of the responses obtained with different control settings clearly demonstrates the need for correct matching of the controller to the system characteristics. Each process is supplied complete with software that allows it to be controlled using a Windows PC via a USB connection.
The plc has the control algorithms implemented in ladder logic and so are fully accessible to the user. To demonstrate industrial control systems, two further controlling devices are available, a full function commercial PID controller with autotune, and a programmable logic controller (PLC). This is demonstrated by a sensor calibration apparatus designed specifically to demonstrate this subject. Another fundamental aspect of process control is an understanding of sensors and how they are calibrated.

The Simple Geared System consists four parallel shafts with fixed and sliding gears and supported by self aligned ball bearings on a base frame. The gear system is attached to a wall supported on two legs for weight hanger travel. By timing the fall of the weight hanger, the acceleration of the system can be calculated. The Simple Geared System is for studying the acceleration of a gear system under different gear ratios. Each pair of adjacent shafts has two transmission ratio, providing 8 different gear ratios between the first and the last shaft. A chord wound around a drum and the weight hanger provides a means of applying a torque. Inertia mass with torque drum is attached to each shaft. A sprocket and lock pin, and a winding handle are provided for raising the weights. All gears are enclosed in a casing with a transparent cover for safety.

Torque measurement for the dynamometer is by load cell, whilst speed measurement uses a magnetic type pick up. Pump suction and delivery heads are monitored by pressure transducers and the flowrate in the circuit can be accurately determined using the built in flow meter. The testing of such a wide range of pumps on a single test unit is made possible by the provision of quick release hose and drive couplings together with quick release pump fixing clamps, enabling changeover to be made easily and efficiently. All data is logged and displayed on the P.C. that is supplied with the unit. Data can be exported to a spreadsheet for processing.
