Thermocouple tables.Full-text restricted to subscribers or individual document purchasers.This textbook provides a fundamental background in the theory of industrial instrumentation and establishes the physical principles and practical techniques used to measure those quantities most important for instrumentation applications. Formulas and equations for sensors are derived from first principle. Enhanced with additional problems and solutions, this book is essential reading for students needing a complete overview of the physical principles and practical techniques used to measure industrial process parameters and how they are applied, together with powerful computational methods in an ever-evolving industry. Two sets of objective questions and keys are also provided. This comprehensive text will provide students and recent graduates with the knowledge to design and build measurement systems for industrial processes.BSc and BEng students in engineering, instrumentation and sensors.Also available in print.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.Alok Barua, PhD was a Professor in the Department of Electrical Engineering, IIT Kharagpur and Adjunct Professor in IIT Jammu.
