A transducer is an electrical device, used to convert one form of energy into another form. Transducers • A Transducer is a device which converts one form of energy into another form. 61240041, 1 yyf , (r from 2013.1 to 2013.12, 0.3 million euro (€) They produce an output signal in the form of some variation in resistance, capacitance or any other electrical parameter, which than has to be converted to an equivalent current or voltage signal. Displacement Transducers and Accuracy Classification per ASTM E2309 Driving test machine variability out of the material testing equation is critical to success. Resistive sensors generally include potentiometer type, contact variable resistance type, resistance strain gauge type and piezoresistive sensor. It is quite difficult to determine the exact magnitude of the physical forces like temperature, pressure, etc. II. • Alternatively, a Transducer is defined as a device which provides usable output response to a specific input measured which may be a physical quantity. Ex:-Resistive,inductive and capacitive transducers -An inverse transducer is defined as a device which converts an electrical quantity into a non-electrical quantity. 1 Classification of transducers Active Transducer The transducers, which develop their output in form of electrical voltage or current Analog and Digital Transducers . The transducer, which converts non-electrical form of energy into electrical form of energy is known as electrical transducer.The block diagram of electrical transducer is shown in below figure.. As shown in the figure, electrical transducer will produce an output, which has electrical energy. Classification of transducer. Even though the image resolution decreases when the depth increases. II. Ø These transducers convert the input quantity into an analog output … The best examples of transducer mainly include a microphone, loudspeaker, etc. When a transducer converts a measurable quantity (sound pressure level, optical intensity, magnetic field, etc) to an electrical voltage or an electrical current we call it a sensor. Analog Transducers . A transducer is a device that is used to convert a physical quantity into its corresponding equivalent electrical signal. We will see a few examples of sensors shortly. A transducer is defined as a substance or a device that converts (or transfers) an input energy into a different output energy. • An TV antenna is a transducer where electromagnetic energy is transformed and reproduced in to electrical energy. Passive: Does sensor draw energy from the signal ? Classification of Transducers based on transduction Principle. In general, the process of transduction involves the conversion of one form of energy into another form. • Antenna: is the most basic transducer and can be made from a simple 36 Sensor classification – physical effect transducers (sensors) employ physical effects to convert a stimulus from a signal domain to another signal domain in \ out radiation mechanical thermal electrical magnetic chemical radiation photo luminance radiation pressure radiation heating photo-conduction photo-magnetic photo-chemical endobj transducers 1. contents what is transducer electrical transducer classification of transducers selection criteria of the transducers basic construction of transducers resistance temperature detector thermistors lvdt rvdt strain guage bourdon … Into an electrical signal which can easily be handled and transmitted for Measurement many sensors been.: Does sensor draw energy from the signal is convex ( see picture below ) the.
