ELASTIC ELEMENT OF FORCE STRAIN GAUGE Russian patent published in 2014 - IPC G01L1/22 

FIELD: measurement equipment.

SUBSTANCE: elastic element of a force strain gauge is made as a whole and comprises an elastic ring, power entering levers, adjoining the inner side surface of the elastic ring along the entire height, cross traction rods connected to the middle part of the elastic ring near the plane of symmetry, perpendicular to its axis, and this plane of symmetry of the elastic ring matches the plane of symmetry of traction rods arranged symmetrically to the second diametral direction of the elastic ring, besides, the distance between axes of traction rods is not more than half of diameter of the external side surface of the ring, and in the middle part of the elastic ring there are through slots, which have height equal to thickness of cross traction rods, and are arranged symmetrically relative to their plane of symmetry, at the same time slots in the circumferential direction are arranged between traction rods and power entering levers.

EFFECT: increased accuracy of measurement of forces of small value at small dimensions of an elastic element having lower stiffness, which makes it possible to expand range of measurement towards small loads.
