Ultra-miniature multi-hole flow angle probes

Abstract

This disclosure provides example methods, devices, and systems for an ultra-miniature, multi-hole flow angle probe. The construction, packaging of a multitude of absolute and or differential pressure transducers or sensors are invented for the purpose of providing highly accurate measurement of flow properties, flow angle in particular. The unique placement of sensors leads to further miniaturization relative to current state of the art. Further the use of closely coupled, differential transducer or transducers achieves higher accuracy measurement of small pressure variations coupled with large mean or average baseline pressures, as is demanded in modern aerodynamic or turbo-machinery devices. The use and installation of ultra-miniature sensors insider the device invented herein achieves higher frequency response than allowable via previous state of the part.
