PU Voyager

1/2" PU Voyager, the most robust Microflown probe

The PU Voyager is the latest addition to the Microflown sensor family. The probe comprises a sound pressure microphone and particle velocity sensor, physically at the same point in a compact anodized aluminum body. The sensors are mechanically protected with a robust housing which includes an embedded metal mesh. This probe is designed to help you evaluate and troubleshoot all kind of noise problems while coping with the most demanding measuring conditions.

Features

  • Broad Band | 20Hz -8kHz
  • Compact design
  • Very Robust
  • Low susceptibility to environment
  • Sound Calibrator compatibility

Applications

  • Noise Source Identification
  • Sound Intensity & Sound Power
  • Industrial testing
  • Troubleshooting
  • PVL & SPL measurements

FIELD CALIBRATION WITH A SOUND CALIBRATOR

PU Voyager will be the first of Microflown sensors to be compatible with a standard sound calibrator for performing field calibration. This field calibration can be performed before or after your mea­surements as quality check to ensure good functioning of the sensor. To achieve this you validate the sensor against a known level, for example alt a level of 94dB at a frequency of 1kHz. To accomplish this our team of expert designed a special adapter suited for the PU Voyager probe and compatible with standard in the market available one-inch sound calibrators.
