U Regular Sensor - 1D ACOUSTIC PARTICLE VELOCITY
1D ACOUSTIC PARTICLE VELOCITY
The ½ inch U Regular integrates one single Microflown sensor. The Microflown is the only transducer which can physically measure the acoustic particle velocity directly. Any sound field is described by two complementary acoustic properties, the acoustic particle velocity vector and the scalar sound pressure. The U Regular captures a one-dimensional component of the particle velocity vector.

Product Overview
NON-CONTACT VIBRATION MEASUREMENTS
In the acoustic near-field of a vibrating surface, particle velocity is often much larger than sound pressure. Provided that the excitation surface has a high impedance, the acoustic particle velocity and the structural velocity become directly proportional. This physical phenomenon enables the use of particle velocity transducers for non-contact vibration measurements. Furthermore, positioning sensors in the near-field of the source can also be beneficial for more than only non-contact vibrations e.g. high-resolution source localization or complex acoustic troubleshooting.
