Abstract

A novel load cell for use in novel wheel load scales and novel weigh-in-motion scales is provided herein. The load cell comprises a metal rod or bar, with a strain transducer secured to a flattened portion of each of the upper and lower faces of the metal bar. A signal wire has its terminal secured to an end face of each of such strain transducer, and a strain relief means is interposed between each such signal wire terminal and its associated strain transducer. When mounted within a closed bore which is parallel to the upper surface of a flat plate of elastic material, e.g., sheet metal, in a particularly-recited manner, an improved wheel load scale or weigh-in-motion scale is provided. This provides a light weight, low profile, scale which is isolated from external interference, which improves the accuracy of the scale.
