STATIC AND FULL PRESSURE SENSOR Russian patent published in 2021 - IPC G01L7/02 G01L11/02 

FIELD: measuring equipment.

SUBSTANCE: invention relates to control and measuring equipment for measuring the altitude and flight speed of aircrafts based on the use of an aerometric method. A static and full pressure sensor contains a case with two holes communicating with the measured medium, inside which an aneroid sensing element is placed, in the form of upper and lower main membranes, in geometric rigid centers of which holes are made, a radiation source mounted on a rack, and two shutters with slots, as well as two optical rulers, and additionally: two racks, a radiation source mounted on a rack, upper and lower pressure gauge boxes, which are hermetically attached, along the perimeter of rigid centers having holes, to inner sides, relatively to a gap of rigid centers of main membranes, while holes of main membranes and additional pressure gauge boxes coincide, shutters with slots are attached to outer sides of rigid centers without holes of the upper and lower pressure gauge boxes, racks of radiation sources, as well as two additional racks, on which two optical rulers are mounted, are attached to the sensor case.

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