STRAIN GAUGE ATTACHMENT UNIT AND IMPACT-RESISTANT SCALES BASED THEREON Russian patent published in 2019 - IPC G01G21/23 

FIELD: measuring equipment.

SUBSTANCE: invention relates to weight measurement equipment. Essence: impact-resistant scales include a base, strain gauges, a load-carrying platform installed on elastic damping elements, movable units transmitting load from elastic damping elements to strain gauges, limiters of movement fixed on the basis of weights, which limit lowering of load-carrying platform on elastic damping elements. Strain gauges, movable assemblies, elastic damping elements and movement limiters are assembled together and structurally arranged in the form of separate detachable units – assemblies of strain gauges installation, located on the basis of weights, on which a rectangular load-carrying platform is placed on top. All assemblies of strain gauges attachment are arranged on their base (1) and are provided with flat support plates (5) in their upper part. In the upper part of the strain gauges of the housing of elastic deformable elements, they are interconnected by flat steel elements (12) with formation of rectangular frame (13) with insertion assemblies at its corners. Similarly, by means of flat steel elements (14) lower surfaces of support plates (5) of installation units are connected to form second rectangular frame (15).

EFFECT: high accuracy of measurements owing to high reliability of connecting working elements and assemblies to each other and reducing the probability of their displacement relative to each other during operation.
