Industrial Process Control Systems, Second Edition By Dale R. Patrick, Stephen W. Fardo * Publisher: CRC * Number Of Pages: 476 * Publication Date: 2009-06-24 * ISBN-10 / ASIN: 1439815763 * ISBN-13 / EAN: 9781439815762 Preface Manufacturing deals with the transformation of materials into marketable products. Industry is primarily responsible for this function in our society. Depending on the product being manufactured, a number of unique processes are generally grouped into systems that accomplish specific manufacturing operations. Systems that respond to temperature, pressure, flow, level, and analytical procedures are commonly used in an industrial setting to manufacture a product. For many years, manufacturing was largely accomplished by manual control operations. These techniques have given way to automated manufacturing operations that control a system with very little human intervention. The computer now serves as a tool to assist in this operation. Computer integrated manufacturing is a buzzword that describes this operation. The computers of a manufacturing facility are often tied together in a large network. These networks are used to schedule and oversee material ordering and routing, parts production, assembly, quality evaluation, testing, and shipment to the customer. The entire operation depends on the control of manufacturing processes. Technically trained personnel must be aware of these operations. Industrial Process Control Systems (2nd Edition) was developed for these people. In this presentation, the systems concept will serve as the basis of our approach to industrial process control. An operating system is first discussed. The system is then divided into a number of essential blocks or parts. The function or role of each block is then discussed. Functional blocks are then divided into discrete components and studied in more detail. Through this approach, one should be able to see how the pieces of a process system fit together. The explanations used in this approach are essentially nonmathematical and apply to typical industrial equipment that is designed to achieve specific manufacturing operations. When math is used, it is presented only to show a practical relationship in the explanation of a process or a control procedure. The organization of each chapter includes objectives, key terms, an introduction, the text, system applications, and a summary. For schools that use this material, the text lends itself well to discussions, written assignments, and associated laboratory activities. For independent study and industrial training programs, this same approach provides a very productive learning procedure. The 2nd edition of this book has been expanded to include the topic of automated processes and robotic systems (Chapter 9). Illustrations have been reviewed and revised and content carefully checked. The authors hope you will find this book informative and easy to understand. We want to thank Brian W. Fardo, who teaches at Berea College, for his assistance in the revision of this book. He has an extensive background in technology systems.
