  • Application Note - Acoustic Transducer Testing with dScope Series III
    The requirements for acoustic testing are quite unique within the field of audio analysis, and testing requires particular care to ensure good rejection of unwanted reflections (echoes and reverberation) and background noise. This is particularly true in a manufacturing environment where acoustic
  • Transducers and Arrays for Underwater Sound
    Transducers and Arrays for Underwater Sound. Presenting basic acoustic concepts and models needed in transducer and transducer array development, this book discusses the six major types of electroacoustic transducers and shows why piezoelectric ceramic transducers are suitable for underwater sound.
  • Dynamic Rotary Torque Measurement using Surface Acoustic Waves (SAW) - A Lonsdale, 2000W (2000)
    . This paper identifies a new, potentially low cost, non-contact, frequency domain strain torque. sensor1 utilising SAW (Surface Acoustic Wave) Technology for surface strain measurement. The. sensor has a short axial length making it flexible in terms of integration into a variety of. applications
  • Guidelines for Specifying Underwater Electroacoustic Transducers
    This paper describes fundamental principles and practical guidelines for specifying or electing underwater transducers. Underwater transducers provide the essential link between the power amplifiers (generators) and the acoustic pressure output, or between the received acoustic pressure
  • High Frequency Properties of Passive Materials for Ultrasonic Transducers
    The acoustic properties of passive materials for ultrasonic transducers have been measured at room temperature in the frequency range from 25 to 65 MHz using ultrasonic spectroscopy. These materials include alumina / EPO-TEK 301 composites and tungsten/EPO-TEK 301 composites. Experimental results
  • Case Study: Surface Defect Analysis of Copper Tubing
    Tests were conducted on Copper tubing of various diameters and wall thickness. These samples were tested in standard resonance mode EMAT's (electromagnetic acoustic transducers) configured for aluminum and steel rod. A rotary encoder input was utilized to generate the data plots of resonant
  • Measurement Microphone Handbook
