“We needed small and accurate board mount pressure sensors. Competitor products we examined couldn’t come close,” said Dr David Birch, research director at SSL, which is a joint venture between the University of Surrey and a unnamed private company.

The sensors, for example, are used in SSL’s Digital Seven-Hole Probe, that uses pressure as a proxy to measure air velocity – speed and direction – for use in wind-tunnel testing, motorsport, and UAVs.
