Scanning Probe

The Scanning Probe comes in three orientations: 0 degrees, 45 degrees and 90 degrees. Close to an object (in the so-called very near field) the particle velocity and the structural vibration coincide. So therefore Microflown sensors can be used for the non contact measurement of the normal component of the structural velocity. The scanning probe is designed in such way that is possible to measure close to a surface

PU-Regular Sound Probe

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...Download brochure

PU-Mini Sound Probe

The functionality of the ½" PU-mini probe is similar to the ½" probe. It measures both particle velocity and sound pressure and the ½" package has a gain of 10dB. The probe is made smaller and is designed for the use in arrays. However it is also used as a single sound intensity probe because its smaller size. Its use is mainly for array applications but it is also use when the regular ½" PU probe is too large and the PU-match is too fragile ...Download brochure

PU-Match Probe

The PU-match is available in three different orientations: 0 degrees, 45 degrees and 90 degrees. 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...Download brochure

USP Regular, Mini & Match

This state of the art sensor is called the USP; the Ultimate Sound Probe. The three dimensional ½ inch USP probe consists of a three orthogonally placed Microflown acoustic particle velocity sensors and a sound pressure microphone. The actual sensor configuration without its cap is less than 5×5×5mm³! Any sound field is described by two complementary acoustic properties, the scalar value 'sound pressure' and the vector value 'particle velocity'. The USP comes standard including a 4 channel signal conditioner ( MFSC-4 ), the necessary cabling, calibration report and two years warranty

High dB Scanning Probe

The ½ inch High dB Scanning Probe is the state of the art velocity sensor. The ½ inch High dB Scanning Probe is sensor based on the MEMS Microflown sensor. The sensor has been improved to handle high dB levels. The sensor can reach particle velocity levels up to 170dB, this in a broad banded frequency range of 20Hz - 20kHz. An example of usage of this probe is: measuring accurate the output of a monopole soundsource. The High dB Scanning Probe comes standard including a 2 channel signal conditioner ( MFSC-2 ), the necessary cabling, calibration report and two years warranty ...Request information

High dB PU Probe

The one dimensional High dB PU Probe consists of a Microflown acoustical particle velocity sensor and a miniature sound pressure transducer. Directly at one spot the sound pressure and acoustic particle velocity are measured. When the standard available PU probes maximum dB level is not sufficient this probe could be the solution. The High dB PU probe is designed to measure dB levels for both sound pressure and particle veloctity up to 130dB. The cap with protective metal mesh should always being kept on the probe. The PU regular can be used for a variety of applications such as the determination of sound intensity, sound power, acoustic absorption, sound leakages etc...Download brochure
