Ultra-Miniature Multi-Hole Flow Angle Probes

摘要

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.

主权项

1. A probe, comprising:
a housing having a front portion with a first oblique side and a second oblique side; a first aperture and a second aperture, wherein the first aperture is disposed on the first oblique side and the second aperture is disposed on the second oblique side; a first transducer disposed in the housing and proximate the first aperture, wherein the first transducer is configured to measure a first environmental condition received at the first aperture; a second transducer disposed in the housing and proximate the second aperture, wherein the second transducer is configured to measure a second environmental condition received at the second aperture; and wherein the width of the housing is less than about five-tenths of an inch and the length is less than about three inches.
