metrology - Free Download PDFInstrumentation is a collective term for measuring instruments that are used for indicating, measuring and recording physical quantities such as flow, temperature, level, distance, angle, or pressure. The term has its origins in the art and science of scientific instrument-making. Instrumentation can refer to devices as simple as direct-reading thermometers , or as complex as multi-sensor components of industrial control systems. Today, instruments can be found in laboratories, refineries, factories and vehicles, as well as in everyday household use e. Elements of industrial instrumentation have long histories.

With a conventional introduction to the principles and standards of measurement, the book in subsequent chapters takes the reader through the important topics of metrology such as limits, fits and tolerances, linear measurements, angular measurements, comparators, optical measurements. The last few chapters discuss the measurement concepts of simple physical parameters such as force, torque, strain, temperature, and pressure, before introducing the contemporary information on nanometrology as the last chapter. Adopting an illustrative approach to explain the concepts, the book presents solved numerical problems, practice problems, review questions, and multiple choice questions. Engineering Metrology and Measurements is a textbook designed for students of mechanical, production and allied disciplines to facilitate learning of various shop-floor measurement techniques and also understand the basics of mechanical measurements. The reason is the electronic devices divert your attention and also cause strains while reading eBooks.
