Ultrasonic Transducer Types: A Comparison of Magnetostrictive vs Piezoelectric Transducers Which Ultrasonic Transducer Type is Best for my Application? This articles describe mechanical transducers like bellows, Bourdon tube, spring, manometer, proving ring, diaphragm, thermocouple bimetal etc. Transducers on the basis of methods of energy conversion used, may be classified into active and passive transducers. Advantages of these Digital tachometers are Simplicity, robustness and low cost. • A transducer is a device, usually electrical, electronic, electro-mechanical, electromagnetic, photonic, or photovoltaic that converts one type of energy or physical attribute to another for various purposes including measurement or information transfer (for example, pressure sensors). Measurement is an important subsystem in any major system, whether it may be a mechanical system or an electronic system. Primary contributions to eccentricity are: 1)Shaft eccentricity (es) 2)Assembly eccentricity (ea) 3)Track eccentricity (et) 4) Radial play (ep), The mean value of the overall eccentricity is given by 2 2 2 2 And assuming that the individual eccentricities are independent variables, the standard deviation of the overall eccentricity is given by 2. Typically, they have small footprints and the frequency varies in the range of 3.5Mhz – 11.5Mhz 13. A measurement system consists of sensors, actuators, transducers and signal processing devices. 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).
