The Microflown
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
-
DC
flow
-
acceleration

Markets
Microflown
Technologies develops and markets innovative
(acoustic) testing techniques to the aerospace, automotive and
defence industry. Within the vehicle manufacturing industry,
Microflown based testing methods are used for both the development
of new prototypes and end of line acoustic testing during
manufacturing.
