The ½ inch Scanning Probe is sensor based on the MEMS Microflown sensor. The Microflown is the only sensor which physically can measure the acoustic particle velocity directly. Any sound field is described by two complementary acoustic properties, the scalar value 'sound pressure' and the vector value 'particle velocity'. In the acoustic near field, acoustic particle velocity is the dominant acoustic property. In the near field the acoustic particle velocity and the structural velocity coincide. This makes the Scanning Probe very suitable for non contact measurements of vibrations. The Scanning Probe is designed is such manner that the probe can used very close to the surface and  capable of reaching difficult accessible spots.  Measuring acoustic particle velocity in the near field can be beneficial for more than only non contact vibration. The susceptibility of a Microflown compared to a microphone to background noise and reflections is minus 40dB. The sensors don’t have the need to create anechoic conditions, so for example products can be tested for quality control in the production line directly. With setting thresholds and define spectrograms of possible product errors not only the Scanning Probe can give you a good or bad as answer for end of line control but also helps you localizing the problem causing the error.

The Scanning Probe is available in three orientations, 0, 45 and 90 degrees, and comes standard including a 2 channel signal conditioner ( MFSC-2 ), the necessary cabling, calibration report and two years warranty.
