Electronic Instrumentation and Measurement PDF
The book Electronic Instrumentation and Measurement has been written to study
the performance, operation and applications of the most important electronic measuring
instruments, techniques and instrumentation methods that include both analog and digital
instruments. It covers a wide range of topics that deal with the basic measurement theory,
measurement techniques, such as analog meter movements, digital instruments, power and
energy measurement meters, AC and DC bridges, magnetic measurements, cathode ray
oscilloscope, display devices and recorders, and transducers. It also explains generation and
analysis of signals along with DC and AC potentiometers, and transformers.
The book is organized into 15 chapters.
Chapter 1 introduces different units of measurement, dimensional notation of physical
quantities, CGS and MKS systems of units. It explains various standards and methods of
measurement, and generalized measurement systems.
Chapter 2 focuses on significant figures, static and dynamic performance characteristics for
selecting a suitable instrument for measurement. It also discusses different types of errors in
measurement, combination of errors, probability of errors and limiting errors. It also describes
the statistical analysis on measurement data to analytically determine the uncertainty of final
measurement result.
Chapter 3 deals with electromechanical instruments to measure physical quantities, including
permanent magnet moving-coil instruments, galvanometers, DC ammeters and voltmeters,
series and shunt ohmmeters, and describes the calibration of instruments.
Chapter 4 presents DC and AC measuring instruments. The instruments that can measure both
DC and AC quantities include moving-iron type instruments, thermocouples, dynamometers,
and transistor voltmeter circuits. The instruments that can measure only AC quantities include
rectifier-type instruments which incorporate rectification techniques such as full-wave rectifier
voltmeter, half-wave rectifier voltmeter, and half-bridge full-wave rectifier voltmeter.
Chapter 5 throws light on digital instruments, such as digital voltmeter, digital multimeter,
and digital frequency meter. It also compares between analog and digital instruments.
Chapter 6 takes into account power and energy measurement instruments, including
electrodynamic wattmeter, low power factor wattmeter, induction-type wattmeter, energy
meters, single-phase induction-type energy meter. It determines power in three-phase circuits
using one-, two- and three-wattmeter methods, and three-phase wattmeter. It also explains
maximum demand indicators and trivector meters.
Chapter 7 focuses on DC and AC measurement bridges. It describes Wheatstone bridge and
Kelvin bridge as DC bridges, Megger for resistance measurement, fall-of-potential method
for measuring earth resistance. It explains different types of AC bridges for measuring
unknown capacitance, resistance, frequency, inductance, and mutual inductance, and describes
miscellaneous bridges, such as parallel T network, bridge T network, Q meter, and Wagner
earthing device.
Chapter 8 explores induction coil, fluxgate, and Hall-effect type magnetometers, and ballistic
galvanometer for measuring flux density of a magnetic field. It determines hysteresis loop
and B-H curve using different methods. It also discusses Hopkinson, Ewing double bar,
Illiovici, and burrow type permeameters along with AC testing of magnetic materials, and
measurement and separation of iron losses.
Chapter 9 presents the structure and working of a cathode ray oscilloscope along with its
probes. It also discusses multi-input oscilloscopes, special types of oscilloscopes including
sampling and storage oscilloscopes, and Lissajous figures.
Chapter 10 familiarizes the reader with various display devices such as decade counting
assembly, light emitting diode, liquid crystal display, nixie tube, segmental gas discharge
display, and dot matrix display. It also explains the concept of X-Y recorders, magnetic
tape recorders, plotters, DC and AC signal conditioning in measurement systems, and data
acquisition system.
Chapter 11 presents the classification of transducers as primary and secondary, analog and
digital, active and passive, and transducers and inverse transducers. It also throws light on the
types of resistive transducers, thermoelectric transducers, inductive transducers, piezoelectric
transducers, photoelectric transducers, pressure transducers, and some miscellaneous transducers including load cells, hotwire anemometer, ultrasonic flow meters, seismic
transducers, and tachogenerators.
Chapter 12 focuses on the concept of generation of signals, different types of signal generators
including pulse and square-wave generators, function generator, arbitrary waveform generator,
audio- and radio-frequency signal generators, frequency synthesizer signal generator, sweep
frequency generator, and video signal generator.
Chapter 13 presents the need for analysis of waveform, different types of analyzers, including
wave analyzer, spectrum analyzer, power analyzer, and harmonic distortion analyzer.
Chapter 14 expounds the basic principle of potentiometers. It also describes different types
of DC potentiometers including the basic slide wire, Crompton’s, multi-range, precision type,
and deflection potentiometers, and AC potentiometers including polar and co-ordinate AC
potentiometers. It also discusses the applications of DC and AC potentiometers, and selfbalancing potentiometer.
Chapter 15 deals with the basic concepts of instrument transformer and its parameters. It
also explains the construction, equivalent circuit, phasor diagrams, characteristics, errors,
reduction methods, and testing methods of both current and potential transformers along
with their differentiation.
