Microflown is a MEMS sensor that was invented to measure the particle velocity. Particle velocity is a vector quantity and measuring this offer lot of advantages over traditional microphones which are capable of measuring only the sound pressure, a scalar quantity. It has become possible to make near field measurements and measurements in the heavy background noise with this sensor. The algorithms used to compute the sound intensity are quite simple and yield better results compared to the ones using microphone sensors. It is a very cost effective solution compared to the system with pressure measurements.
A normal acoustic sensor (microphones) uses air pressure for converting acoustical signals to electrical signals and viceversa. The design of these transducers hasn't changed much since their development decades ago. Most microphones still operate with a membrane.
The Microflown element is used in several standard products. One or more Microflowns are combined with an optional pressure microphone. The Scanning probe uses only a single Microflown element, ½” PU probe consists of a Microflown and a 1/10” pressure element and is packaged in a ½” package that has a gain of roughly 10dB, ½” mini PU probe is similar to the ½” probe but it is made smaller, the pu match is the smallest PU probe and the USP consists of three orthogonally placed Microflowns and a pressure element.
The standard probes are the probes that are sold most frequently.
All probes are checked and calibrated when they leave Microflown Technlogies.
All probes are sold complete, so ready to use; cabling, signal conditioning etc. is included.
All sensor configurations, orientations, cable lengths, connectors, preamplifiers can be changed on request.
