AEROMETRIC PRESSURE SENSOR Russian patent published in 2019 - IPC G01L7/08 G01L11/02 

FIELD: measuring equipment.

SUBSTANCE: invention relates to checkout technique and can be used to measure the altitude and speed of flight of aircraft based on the use of the aerometric method. Disclosed is an aerometric pressure sensor, having a housing, inside which an aneroid sensitive element is formed, formed by upper and lower membranes, wherein the housing has two openings connected to the measured medium, a radiation source mounted on the post, and two curtains with slots, fixed on the same post, as well as two photodetector lines. At that, in geometrical centers of upper and lower membranes ferromagnetic elements are attached from their external sides, at that on inner surface of housing coaxially and with gap in relation to introduced ferromagnetic elements permanent magnets are installed.

EFFECT: high sensitivity and accuracy of measuring pressure and altitude, and aircraft flight speed, as well as high functionality of the elastic sensitive element.
