Preface
The third edition of Measurement and Control Basics is a thorough and comprehensive treatment of the basic principles of process control and measurement. It is designed for engineers, technicians, management, and sales personnel who are new to process control and measurement. It is also valuable as a concise and easy-to-read reference source on the subject.This new edition provides expanded coverage of pressure, level, flow,temperature, analytical measurement, and process control computers.Material on the proper tuning of control loops was added to Chapter 1,and expanded coverage of control loops was added to Chapter 2. Chapter3 includes a more complete discussion of electrical and electronic fundamentals needed in process control and instrumentation.The discussion of the basic principles underlying pressure measurement has been expanded to include a discussion of sensor characteristics and potentiometric-type pressure sensors. Extensive coverage was added on typical pressure transmitter applications. The discussion on level measurement has been increased with the addition of several common level instruments and switches such as displacers, tape floats, microwave, and radar. The chapter on temperature measurement has been improved by adding new illustrations and a section on radiation pyrometers. Coverage of analytical measurement and control in Chapter 8 was increased by the addition of a section on the principles of electromagnetic radiation and its application to analytical measurement. Three sections were also added to Chapter 8 on photoconductive sensors, photomultiplier tubes, and turbidity analyzers.Chapter 9 on flow measurement contains new coverage on Reynolds Number and fluid flow profiles. The discussion of the basic principles of fluid flow has been expanded and improved in Chapter 9. A discussion on types of control valves and control valve actuators was added to Chapter10 and the section on control valve sizing was expanded and improved.All of the chapters have been supplemented with new or improved example problems and exercises. Most of the illustrations in the book have been revised and improved.
