<p>The invention relates to mass measurement engineering and can be used in different industrial sectors for weighting in movement and in static position as well as a diagnostic and inspection facility for measuring under the rail base the weight per axle of rolling stock. The invention makes it possible for transmitting efforts to a measuring element without using intermediate parts and devices, to improve accuracy and to use standard fasteners for ferro-concrete sleepers and rails. The inventive weighting rail plate is in the form of a plate for attaching a rail to a ferro-concrete sleeper and differs in that it is simultaneously used as a strain sensor and as a rail fastener, in that force-sensing elements in the form of strain concentrators are arranged inside said plate, in that said strain concentrators are provided with resistive-strain sensors and temperature compensators glued thereto and are connected according to a bridge circuit in such a way that the rail plate converts the mechanical force applied to the rail by a wheel into a proportional electric signal.</p> |
