USE SCENARIOS

  • Calibration reference standards 
  • Ultrasonic measurements in liquids 
  • Cavitation measurements 
  • Laboratory and industrial measurements in liquids and gases 
  • As underwater projectors (8103, 8104 and 8105) 
  • Noise measurements in humid and polluted atmospheres
    A wide-range standard measuring transducer for making absolute sound measurements over the frequency range 0.1Hz to 120 kHz with a receiving sensitivity of −205 dB re 1V/μPa. It can also be used as a sound transmitter (projector) which makes it ideal for calibration purposes by the reciprocity, calibrated-projector and comparison methods.
