BASE PLATE ON THE GROUND PRESSURE SENSOR Russian patent published in 2016 - IPC G01L7/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment, in particular to measurements of base plate pressure on ground of such structures, as NPP reactor compartments, bridges, dams, high-rising and industrial buildings, and can be used in stress-deformed state of soils monitoring systems. Proposed base plate pressure sensor on the ground includes cylindrical housing with bottom, rigid disk, measuring device made in form of beams with resistance strain gauges attached thereto, and flexible element arranged along housing and rigid disk axis of symmetry, wherein flexible element is made in form of cylinder with inner cavity, which first end surface has concave spherical surface in contact with housing projection convex spherical surface, second side end surface in contact with rigid disc, and measuring device arranged along flexible element and rigid disc axis and connected to them is made in form of a polyhedron with three faces, at least, on each face of which stretched string with electromagnetic system is attached, wherein strings axes are arranged in symmetry to flexible element axis.

EFFECT: technical result consists in improvement of accuracy and reliability of measurement by means of measurement channels redundancy.
