INTRODUCTION TO SENSORS - The National Academies Press

The committee recognizes that, for the purpose of this report, the output of a sensor may be any form of energy. Many early sensors converted (by transduction) a physical measurand to mechanical energy; for example, pneumatic energy was used for fluid controls and mechanical energy for kinematic control.
