In this book Ian Sinclair provides the practical knowhow required by technician engineers, system designers and students. The focus is firmly on understanding the technologies and their different applications, not a mathematical approach. The result is a highly readable text which provides a unique introduction to the selection and application of sensors, transducers and switches, and a grounding in the practicalities of designing with these devices. The devices covered encompass heat, light and motion, environmental sensing, sensing in industrial control, and signal-carrying and non-signal switches.About the AuthorIan Sinclair, Long-standing technical author, UKTable of ContentsPreface Strain and pressure Position, direction, distance and motion Light and associated radiation Temperature sensors and thermal transducers Sound, infrasound and ultrasound Solids, liquids and gases Environmental sensors Other sensing techniques Instrumentation techniques Switch Principles, Switch mechanisms, Signal carrying switches Index
