Use

The PU-match is used when small size is important. This is when the measurement space is limited or hard to reach the physical size of the probe is an important property. If for instance the sound power output of a dashboard in a car has to be determined, the part where the front window comes close to the dashboard is impossible to reach with a traditional p-p probe. A p-u probe is the only option then.
A small size is also needed to determine the sound intensity (or sound energy, etc.) of small objects (like hearing aids, cell phones components on printed circuit boards, etc.). The sound probe must be small to get any special resolution of these small noise sources.
Because the sound pressure and particle velocity are directly available the data acquisition is relatively simple, it can for instance be done with the use of a sound card of a personal computer.

The PU-match is available in three different orientations:

The PU-match comes with:

  • Signal conditioner with an option for correcting the frequency and phase response
  • powering module
  • sensor cable
  • option for 12V powering
  • A protective metal case is provided to ensure that the probe is not damaged when it\'s not in use.
