PRESSURE SENSOR USING OPTICAL METHOD OF INFORMATION TRANSFORMATION Russian patent published in 2018 - IPC G01L7/00 

FIELD: 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. Inventive pressure sensor comprises a housing that has two openings communicating with the medium to be measured and within which an aneroid sensing element formed by the two membranes is disposed. Sensor additionally introduced a radiation source fixed to the rack, and two curtains with slots fixed on the same rack, as well as two photodetector rulers, the membranes of the sensor element are divided into upper and lower and are permanently sealed around the perimeter, forming an airless gap. In this case, the housing openings are located above and below the gap, and the stand is located inside the gap and is attached to the body. Photodetector rulers located in the gap are attached to the upper and lower membranes respectively and face the corresponding slits of the shutters.

EFFECT: increase in the efficiency and economy of the device operation.
