SENSITIVE ELEMENT Russian patent published in 2017 - IPC G01L1/00 

FIELD: measuring equipment.

SUBSTANCE: inventive sensing element comprises a resilient rod with a cutting depth of 1.5-2 diameters of a strain-gauge wire, both ends of which are provided with arms of equal length and arranged perpendicularly to the axis of the elastic rod, and a tensile resistive wire of compression and tension, unidirectionally located with interference in the grooves of the cutting, The cross-section of the elastic rod is made in the form of a rectangle with curvilinear sides convex outwards, with round bevels, and the cutting is performed on the facets of an elastic rod with the step of a large diameter of the strain-gauge wire, the levers being mounted on the greater curved side of the elastic rod, and the anchor ends of the strain-gauge wire are fixed on the smaller curvilinear side.

EFFECT: increasing the accuracy of measurements of dynamic loads in a wide range, including loads of small magnitude.
