The Essentials of Process Control (EPC) range of products takes students through the fundamentals of 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 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. To demonstrate industrial control systems, two further controlling devices are available, a full function industrial PID controller with autotune, and a programmable logic controller (PLC).

This provides a cost-effective way of teaching a wide range of process control techniques, including temperature measurement and flow control. More sophisticated aspects of process control can be addressed by adding optional extras to the basic system. The PCT40 is computer controlled with optional manual control available using the PCT43 Electronic Control Console.

The TH range is designed to introduce students to the fundamental principles of thermodynamics. Exploring basic concepts such as temperature and pressure measurement, plus an introduction to the relationships between these fundamentals; first and second low, the principles of reversibility, entropy, enthalpy etc. The equipment enables the student to gain a true understanding of these difficult concepts, which are so important in all aspects of engineering.

Armfield through their CE and UOP range of products offer the most comprehensive, diverse and technically current group of products of any manufacturer, bringing both basic principles and complete unit operations to the modern educational laboratory.
