The Dynamic Performance of Flexural Ultrasonic Transducers
Flexural ultrasonic transducers are principally used as proximity sensors and for industrial metrology. Their operation relies on a piezoelectric ceramic to generate a flexing of a metallic membrane, which delivers the ultrasound signal. The performance of flexural ultrasonic transducers has been largely limited to excitation through a short voltage burst signal at a designated mechanical reson...
متن کاملPassive Materials for High Frequency Ultrasound Transducers
In this paper, the elastic properties of passive materials (matching, backing and lens materials) for ultrasound transducers are explored at room temperature in the frequency range of 25-65MHz using the ultrasonic spectroscopy method. AlurninaJEPOTEK 301 and tungsten/EPO-TEK 301 composites were fabricated and measured. Experimental results display a monotonic rise in acoustic impedance of the c...
متن کاملMeasurement Algorithm of Two-Dimensional Wind Vector using Ultrasonic Transducers
Ultrasonic wind speed measurement technique obtains more and more extensive use in the field of Meteorology and Environmental Protection etc. When designing an ultrasound wind vector instrument, synthesizing wind vector information, containing wind velocity vector and wind angle, is of prime importance to accomplish accurate measurement. This paper presents synthesis algorithm of ultrasonic 2D ...
متن کاملUltrasonic measurement of gas flow using electrostatic transducers.
Ultrasonic gas flowmeters typically use narrowband piezoelectric transducer arrangements for interrogating the flow of gas in a pipe. In this work, the suitability of broadband electrostatic transducers operating at frequencies of up to 1 MHz for ultrasonic measurement of gas flow has been investigated. The transit time method of ultrasonic gas flow measurement was adopted and experiments were ...
متن کاملMeasurement of complex impedance of ultrasonic transducers
The automated system for ultrasonic transducer complex impedance measurement using the sine wave correlation for signal amplitude and phase extraction is presented. The system contains the direct digital synthesis (DDS) generator and two ADC channels with a common reference frequency source. In such a case the frequency error between the excitation and the measurement channels is reduced. The s...
