PRESSURE SENSOR USING OPTICAL METHOD FOR INFORMATION CONVERSION Russian patent published in 2022 - IPC G01L11/02 

FIELD: measuring equipment.

SUBSTANCE: invention relates to control and measuring equipment and can be used for measuring the altitude and velocity of flight of aircraft based on the use of the aerometric method. Apparatus containing a body with an upper base and a lower base, wherein each of the bases has a hole in communication with the measured medium, and a radiation source located on a stand attached to the inner surface of the body, and two shutters with slits attached to the same stand, as well as two lines of photovoltaic receivers, additionally includes two manometric boxes, with a hole made in one of the rigid centres of each of said boxes, wherein the rigid centres of the manometric boxes with holes are attached tightly to the upper and lower bases of the body so that the holes in the bases and the boxes are matched, and the lines of the photovoltaic receivers are attached to the rigid centres of manometric boxes without holes and face the corresponding slits in the shutters.

EFFECT: higher sensitivity and accuracy of pressure measurement.
