SENSOR FOR MEASUREMENT OF GROUND PRESSURE Russian patent published in 2018 - IPC G01N33/24 G01L9/00 E02D1/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to technical devices for measuring pressure in ductile and bulk media, incl. soils. In the pressure sensor including the housing 1, the sensor element 2, the measuring device 3 and a force-receiving system with an abutment 11, the force-receiving system is made in the form of two hard disks 5 and 6, between which the sensor element 2 is arranged in the form of a disk of resiliently compressible material, the hard disks 5 and 6 and the sensor element 2 coaxially oriented relative to each other by the cylindrical guides 7, equipped with adjusting nuts 8 of the precompression of the sensing element, and one of the hard disks 5 is free to move along the guides 7 and is equipped with a centering hole 9 for mating with the spherical head 12 of the stop 11 fixed to the body 1 and symmetrically fixed to it by measuring devices 3.

EFFECT: increasing the effectiveness of measuring the contact pressure of the ground base, in comparison with existing analogues, due to the possibility of obtaining it at a given point of contact of the structure with the ground, simplification of design and operation of the sensor for measuring ground pressure.
