Generally, sensors are used in industry to obtain quantitative or binary information at a precise moment and under certain measurement conditions. Consequently, there are numerous parameters available to help in deciding which sensor should be used for a particular task to decide to choose a particular measuring equipment. This title provides a comprehensive guide to sensors and their applications. Part 1 outlines the fundamental principles of technologies of measurement, while Part 2 gives practical examples of sensor use in numerous fields, as well as outlining why certain sensors are better suited to certain applications. As such, this book will be of invaluable use to readers wanting to gain a better understanding of sensors, both in a theoretical and a practical context.
