Sensor fundamentals


In this chapter, we first introduce a notation system for the quantities used in this book and an unambiguous set of symbols for each quantity. Second, a formal description of relations between quantities, based on energy considerations, is presented from which particular physical effects are derived serving for specific groups of sensors that are discussed in later chapters. Various frameworks developed for a systematic description of sensors are briefly explained: they are based on measurand, application field, port models, conversion principles, and energy domain.
