Definitions for "Transducer"
Any device or component that converts an input signal of one form to an output signal of another form-for instance, a piezoelectric transducer converts pressure waves into electrical signals, or vice versa.
device that provides an output quantity having a determined relationship to the pressure. Commonly used in pressure measurement to refer to pressure transducers with voltage outputs.
Device that accepts an input of energy in one form and produces an output of energy in some other form, with a known, fixed relationship between the input and output. One widely used class of transducers consists of devices that produce an electric output signal, e.g., microphones, phonograph cartridges, and photoelectric cells
