A transducer is a device that converts energy from one form to another. In general, a transducer converts a signal into one form of energy in one signal into another. Transducers are often used within the limits of automation, measurement and control systems, where electrical signals are converted to other physical quantities (energy, force, torque, light, movement, position, etc.). The process of converting one form of energy to another is called transduction.
