Enhanced descriptions from Syndetics:

Nearly all industrial processes require objects to be moved, manipulated or subjected to some sort of force. This is frequently accomplished by means of electrical equipment (such as motors or solenoids), or via devices driven by air (pneumatics) or liquids (hydraulics).This book has been written by a process control engineer as a guide to the operation of hydraulic and pneumatic systems for all engineers and technicians who wish to have an insight into the components and operation of such a system.This second edition has been fully updated to include all recent developments such as the increasing use of proportional valves, and includes an extra expanded section on industrial safety. It will prove indispensable to all those wishing to learn about hydraulics and pneumatics.

CHOICE Review

The publisher's abstract notes that "practically every industrial process requires objects to be moved. . .this is generally accomplished by. . .devices driven by air or liquids." This manual is intended as a self-study guide for practicing technicians and engineers, but it could also serve as a text in a senior-level elective course in machine design. It is thoughtfully organized and carefully written for the most part: Parr first introduces simple devices applied to steady-state operation, before challenging the reader with more intricate regulators and transient response. (More complete explanations would have been helpful in these chapters.) The book concludes with some applications to process control. By intent, a background in fluid mechanics is not necessary to understand anything in the book, but it would be essential in judging the feasibility of specific applications. For the same reason, Parr has omitted any discussion of proper sizing. In addition, the book contains no specific instances of industrial practice, nor does it contain a bibliography or citation list of advanced topics. For these reasons the book is adjudged as too narrow in scope to justify its considerable cost. -M. B. Snyder, University of Nevada, Reno

Andrew Parr is an Industrial Control Engineer, recently retired from ASW Sheerness Steel, Sheerness, UK who worked in the steel industry for over thirty years. In 1980 he began specializing in sequence and closed loop control systems using Programmable Controllers (PLCs) with hydraulic and pneumatic actuators. He has written fifteen books on electronics and process control including Logic Designers Handbook, Industrial Control Handbook, Programmable Controllers, Control Engineering, along with many amateur- level books, among them Introduction to Operational Amplifiers. His books have been widely translated into many languages, including Japanese, Polish, and Swedish. He and has presented papers at various international conferences, including ones on "Automation Systems in the Steel Industry" and on "Automated Fault Diagnostics".
