The Microflown is the worlds first and only MEMS technology based sensor that can measure
the acoustic particle velocity. By measuring the temperature difference in the cross section
of two extremely thin platinum wires placed in parallel, this extremely fast mass flow sensor
is capable of monitoring the movement of air particles. Any sound field is described
completely by both the (scalar) value sound pressure and the (vector) value acoustic
particle velocity. Understandably, acoustic testing becomes much easier if both acoustic
quantities can be measured. But the Microflown sensor platform can also be used to measure:
structural velocity
sound pressure
temperature
Applications
Microflown Technologies offers superior applications such as:
fast and broad banded vehicle interior noise source path contribution analysis
( portable ) near field acoustic camera's
sound source triangulation techniques in the acoustic far field
in situ determination of acoustic properties of materials
non contact vibration measurements / modal analysis
