The book covers all the aspects of the course Electrical Instrumentation and Process Control for the undergraduate students. The various types of transducers, measurement of flow, pressure, level, velocity, discussion of telemetry, data acquisition system, display devices, recorders, computer aided measurements, optic fiber and smart sensors and various types of controllers are explained in the book with the help of comprehensive approach. The book starts with classification, characteristics and selection factors for the transducers. It also explains the resistive transducers, strain gauge, RTD, thermistors, thermocouples, inductive transducers and LVDT. Then the book covers the capacitive, piezoelectric and Hall effect transducers. It also includes the methods of measurement of motion pressure, flow, velocity and level. The book also includes the chapters on telemetry and data acquisition system. The chapter on display devices and recorders includes the discussion of various display devices such as LED, LCD, dot matrix and their applications. The discussion of oscilloscope measurements, Lissajous figure and digital storage oscilloscope is included in support. The book further explains various types of recorders, spectrum analyzer, digital data recording and techniques of DAC and ADC. The inclusion of recent developments in measurements such as computer aided measurement, optical fiber and smart sensors is the feature of the book. Finally, various controllers used in process control are discussed including the discussion of electronic, pneumatic and digital controllers. The book also incorporates the discussion of PLC and its applications. Each chapter gives the conceptual knowledge about the topic dividing it in various sections and subsections. Each chapter provides the comprehensive theory and real time practical examples. The book explains the philosophy of the subject which makes the understanding of the concepts very clear and makes the subject more interesting.
