SENSOR FOR MEASURING SOIL PRESSURE Russian patent published in 2021 - IPC G01L9/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to technical apparatuses for measuring the pressure in plastic and bulk media, including soils. The sensor for measuring soil pressure comprises a body, a force-sensing system in the form of two hard disks, wherein a sensing element in the form of a disk made of an elastic compressible material is placed between said disks, wherein the hard disks and the sensing element are coaxially oriented relative to each other with cylindrical guides, one of the hard disks is configured to move freely along cylindrical guides, a fixed disk placed coaxially to the body, and a measuring tool. The sensing element and the movable hard disk are made in the form of a ring, the movable hard disk is equipped with three stops located at three points at an angle of 120 degrees, the measuring tool is made in the form of a displacement sensor, and the fixed hard disk is equipped with a centering slot for coupling with the tip of the displacement sensor located along the axis of symmetry of the disks and attached on the movable hard disk.

EFFECT: reduction in the size of the sensor for measuring soil pressure, a reduction in the amount of linear displacement meters, simplification of manufacturing and operation.
