  • Patent number: 11733085
    Abstract: Weigh-in-motion sensors comprise a beam including a plate with a load-bearing surface, and a tube portion including a base wall and a cover and defining a cavity therebetween. A sensing package is disposed within the cavity and is under pre-load with the cover and the base wall. The sensing package comprises a piezoelectric element. The base wall includes an aperture extending from a mounting surface to the cavity. The aperture includes a fastener therein to secure the sensing package within the cavity. The fastener is sized having a cross-section dimension taken through a center axis of the fastener that is greater than that of a cross-section dimension of the piezoelectric element taken along the fastener center axis. In an example, the fastener has a cross-section dimension sized about 10 percent or greater in dimension than that of the respective cross-section dimension of the piezoelectric element.
