Microflown Sound Pressure & Particle Velocity Sensors

PU-Regular Probe

Use

The ½" probe is a general purpose sound probe that measures both particle velocity and sound pressure.
The ½" package is robust so this way of packaging is the best for "non laboratory" use. The wind caps and mountings etc. of a regular ½" pressure microphone probe can be used.
The 1/2" packaging has an acoustic gain of 10dB. This has the result that the selfnoise improves 10dB but that the upper sound limit decreases 10dB to 120dB. The 1/2" package has no influence of the sound field below 10kHz and therefore the use of the ½" PU-mini probe recommended below 10kHz.

Because of the dimensions this probe are similar to a half-inch pressure microphone, all standard mountings and windshields can be used.
Because the sound pressure and particle velocity are directly available the data aquisition is relatively simple, it can for instance be done with the use of a sound card of a personal computer.
