Electrical Measurements and Instrumentation

The importance of measuring instruments and transducers is well known in the various engineering fields. The book provides comprehensive coverage of various electrical and electronic measuring instruments transducers data acquisition system storage and display devices . The book starts with explaining the theory of measurement including characteristics of instruments classification standards statistical analysis and limiting errors. Then the book explains the various electrical and electronic instruments such as PMMC moving iron electrodynamometer type energy meter wattmeter digital voltmeters and multimeters. It also includes the discussion of various magnetic measurements instrument transformers power factor meters frequency meters phase meters and synchros. The book further explains d.c. and a.c. potentiometers and their applications.The book teaches various d.c. and a.c. bridges along with necessary derivations and phasor diagrams. The book incorporates the various storage and display devices such as recorders. plotters printers oscilloscopes LED LCDs and dot matrix displays. The chapter on transducers is dedicated to the detailed discussion of various types of transducers such as resistive capacitive strain gauges RTD thermistors inductive LVDT thermocouples piezoelectric photoelectric and digital transducers. It also adds the discussion of optical fiber sensors. The book also includes good coverage of data acquisition system data loggers DACs and ADCs. Each chapter starts with the background of the topic. Then it gives the conceptual knowledge about the topic dividing it in various sections and subsections. Each chapter provides the detailed explanation of the topic practical examples and variety of solved problems. The book explains the philosophy of the subject which makes the understanding of the concepts very clear and makes the subject more interesting.
