Excerpt from Electric and Magnetic Measurements and Measuring Instruments The following volume has been written for the use of those who have to do with electrical and magnetic measurements in one form or another, and as these must be made in practically all branches of the profession, from the simple testing out of lines and resistances to the most elaborate determination of designs, it is hoped that its Sphere of usefulness will be quite large. The subjects have, throughout, been approached with a View toward their use by users, not manufacturers, of measuring apparatus, that is to say the book is in no sense intended as a treatise on the design and construction of instruments, the circle interested being decidedly limited. Descriptions are, however, given of apparatus as well as of methods of test, because knowl edge of the manner in which a principle is utilized in concrete instruments often suggests, to one having a determination to make but is at the same time without the particular form of appliance ordinarily employed for that purpose, means of adap ing thereto some other device which is at hand. Further, in illustrating examples of instruments for different kinds of work, there has been in mind the idea that these will enable engineers to decide, with the aid of their general engineering knowledge, which are the best suited to their particular requirements.

Weighing in on the growth of innovative technologies, the adoption of new standards, and the lack of educational development as it relates to current and emerging applications, the third edition of Introduction to Instrumentation and Measurements uses the authors’ 40 years of teaching experience to expound on the theory, science, and art of modern instrumentation and measurements (I&M). What’s New in This Edition: This edition includes material on modern integrated circuit (IC) and photonic sensors, micro-electro-mechanical (MEM) and nano-electro-mechanical (NEM) sensors, chemical and radiation sensors, signal conditioning, noise, data interfaces, and basic digital signal processing (DSP), and upgrades every chapter with the latest advancements. It contains new material on the designs of micro-electro-mechanical (MEMS) sensors, adds two new chapters on wireless instrumentation and microsensors, and incorporates extensive biomedical examples and problems. Containing 13 chapters, this third edition: Describes sensor dynamics, signal conditioning, and data display and storage Focuses on means of conditioning the analog outputs of various sensors Considers noise and coherent interference in measurements in depth Covers the traditional topics of DC null methods of measurement and AC null measurements Examines Wheatstone and Kelvin bridges and potentiometers Explores the major AC bridges used to measure inductance, Q, capacitance, and D Presents a survey of sensor mechanisms Includes a description and analysis of sensors based on the giant magnetoresistive effect (GMR) and the anisotropic magnetoresistive (AMR) effect Provides a detailed analysis of mechanical gyroscopes, clinometers, and accelerometers Contains the classic means of measuring electrical quantities Examines digital interfaces in measurement systems Defines digital signal conditioning in instrumentation Addresses solid-state chemical microsensors and wireless instrumentation Introduces mechanical microsensors (MEMS and NEMS) Details examples of the design of measurement systems Introduction to Instrumentation and Measurements is written with practicing engineers and scientists in mind, and is intended to be used in a classroom course or as a reference. It is assumed that the reader has taken core EE curriculum courses or their equivalents.

"Joseph F. Keithley, a modern pioneer of instrumentation, brings you a fascinating history of electrical measurement from the ancient Greeks to the inventors of the early twentieth century. Written in a direct and fluent style, the book illuminates the lives of the most significant inventors in the field, including George Simon Ohm, Andre Marie Ampere, and Jean Baptiste Fourier. Chapter by chapter, meet the inventors in their youth and discover the origins of their lifelong pursuits of electrical measurement. Not only will you find highlights of important technological contributions, you will also learn about the tribulations and excitement that accompany the discoveries of these early masters. Included are nearly 100 rare photographs from museums around the world. THE STORY OF ELECTRICAL AND MAGNETIC MEASUREMENTS is a ""must read"" for students and practitioners of physics, electrical engineering, and instrumentation and metrology who want to understand the history behind modern day instruments."

This book is a graduate-level introduction to the theory of electro-magnetic flow-measurement. Although the sophistication of the instrumentation has changed radically since Shercliff's book was first published, the theoretical principles expounded in the book are still relevant and sound. Students of mechanical engineering and research workers will find this reissue useful.
