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 acquisition is
relatively simple, it can for instance be done with the use of a sound
card of a personal computer.
The PU-regular 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.
