Jones Instrument Technology Automatic Instruments And Measuring Systems 4e Vol 5 Pb

Jones' Instrument Technology, Volume 5: Automatic Instruments and Measuring Systems deals with general trends in automatic instruments and measuring systems. Specific examples are provided to illustrate the principles of such devices. A brief review of a considerable number of standards is undertaken, with emphasis on the IEC625 Interface System. Other relevant standards are reviewed, including the interface and backplane bus standards. This volume is comprised of seven chapters and begins with a short introduction to the principles of automatic measurements, classification of measuring systems, application areas, and interface systems. The discussion then turns to the connection of the individual units of an IEC-interface-based measuring system, along with control units, computers, programmable calculators, and special system controllers. The chapters that follow focus on the building blocks of automatic measuring systems, their design and assembly, and the merits and uses of IEC system analyzers. The final chapter reviews alternative serial and parallel systems and interfaces, as well as the standards available. This monograph will be invaluable to electronics and electrical engineers.

Instrument Technology, Volume 1 focuses on the instruments used in the measurement, recording, and control of critical variables in industrial processes. More specifically, measurements of pressure, liquid level in a tank or vessel, flow, and temperature are discussed. Instruments are classified according to the physical principle upon which they are based. The discussion begins by introducing the reader to the system of units of measurement used throughout the text. This topic is followed by four chapters, each dealing largely with the mathematics and physics of the instruments, which are classified according to the decimal system. The first chapter describes the principles on which the measurement of pressure and the transmission of force by a fluid depend. Before considering the actual methods of measuring pressure, the book first explains the difference between absolute and differential pressure. The second chapter discusses how the level of liquid in a tank or vessel is measured using direct methods and pressure-operated types. The third chapter focuses on the measurement of flow using quantity meters and rate-of-flow meters. The final chapter is concerned with temperatures measured on different thermometers and the two fixed points used to compare such measurements: the lower fixed point (ice-point) and the upper fixed point (steam-point). This book is intended for instrument and chemical engineers, as well as for students studying both craftsmen and technician courses.
