Abstract: A measuring plate with at least one strain gauge and upon which a wheel of a vehicle can rest to generate a signal which is used to indicate or register the wheel load or axle load of the road vehicle, is received in a frame and has edges which extend transversely of the direction of vehicle travel. According to the invention, these edges are bevelled or partly cut away so as to be overhung by complementarily shaped sides of the frame. These edges also are provided, along the bottom of the plate, with elastic bars or ribs which rest upon and support the center of the plate above a support plate or body disposed below the measuring plate. The plate can have these edges covered with an elastic material, especially a clear elastomer or the entire measuring plate can be sheathed in the elastomer.

Abstract: A device for measuring the wheel or axle load of a road vehicle comprises a plate supported along its periphery at selected points or by knife edges in a frame. Along two imaginary lines of the plate, spaced apart by a distance greater than the length of a contact zone of a wheel on the plate, there are provided at least two pairs of wire strain gauges. Each pair of wire strain gauges includes a wire strain gauge extending in the direction of displacement of the wheel, i.e. perpendicular to the imaginary lines and a wire strain gauge parallel thereto. The measuring signals of the wire strain gauges is added and a multiplication factor a of about 0.3 is provided between the measuring signals of the two gauges of each pair which are added.
