AEROMETRIC PRESSURE SENSOR Russian patent published in 2020 - IPC G01L11/02 

FIELD: monitoring and measuring equipment.

SUBSTANCE: invention relates to instrumentation and can be used to measure the altitude and speed of flight of aircraft based on the use of the aerometric method. Aerometric pressure sensor comprises a housing having two openings communicating with the measured medium, and inside which there is an aneroid sensitive element formed by upper and lower membranes, fixed tightly along perimeter to body and forming gap by height spacing, wherein two holes of the housing are located above and below the gap, and in the gap there are photodetector lines, wherein in the gap there is a device for forming optical beams, rigidly attached to the side wall of the housing. Photodetector bars are attached to the same side wall of the housing, and curvilinear reflectors of optical radiations are installed in geometric centres of the upper and lower membranes.

EFFECT: increasing the sensitivity and accuracy of pressure measurement both in altitude and in flight speed of the aircraft.
