DEFINATION OF TRANSDUCER

A transducer is a device that transforms a signal from one energy form to another energy form. One example is a speaker, which converts an amplifier's electrical energy into sound waves or mechanical energy. Energy forms consist of (but are not confined to) mechanical, electrical, chemical, electromagnetic, thermal and acoustic energy.

CLASSIFICATION OF TRANSDUCERS

RESISTIVE TRANSDUCERS

The transducer whose resistance varies because of the environmental effects such type of transducer is known as the resistive transducer.The resistive transducer is used for measuring the physical quantities like temperature, displacement, vibration etc

CAPACITIVE TRANSDUCERS

The capacitive transducer is used for measuring the displacement, pressure and other physical quantities. The capacitive transducer contains two parallel metal plates. These plates are separated by the dielectric medium which is either air, material, gas or liquid.

INDUCTIVE TRANSDUCERS

An inductive transducer (electromechanical) is an electrical device used to convert physical motion into modifying within inductance. This article discusses what an Inductive Transducer, types of transducer, working principle, and its applications.

ACTIVE TRANSDUCERS

Active transducer is a transducer, which converts the non-electrical quantity into an electrical quantity. Let us consider the non-electrical quantities such as pressure, illumination of light and temperature.

PASSIVE TRANSDUCERS

Passive transducer is a device which converts the given non-electrical energy into electrical energy by external force. Resistance strain gauge, Differential Transformer are the examples for the Passive transducers.

ELECTROMECHANICAL TRANSDUCERS

Electromechanical transducer, any type of device that either converts an electrical signal into sound waves (as in a loudspeaker) or converts a sound wave into an electrical signal (as in the microphone). Many of the transducers used in everyday life operate in both directions, such as the speakerphone on certain intercoms.

TRANSDUCERS ACTUATING MECHANISMS

The actuating mechanism of proposed motor indicates that the key to form a traveling wave in the cylinder is the degeneration between the vibration modes of cylinder and transducer. Then, a composite transducer with near resonance frequency was designed.
