Abstract
A pneumatic bridge air gauge sensor. A measurement leg and a reference leg are used to measure a gap between a measurement probe and a surface. The two legs are initially balanced resulting in no air flow therebetween. A mass air flow sensor coupled between the two legs detects the mass air flow between the two legs resulting from a change in the gap distance from the balanced state.
