1. A weigh-in-motion sensor construction comprising:
a beam elongated along a depth axis of the sensor construction, the beam comprising:
a plate with a load-bearing surface;
a tube portion including a base wall and a cover and a cavity between the base wall and the cover; and
a sensing package disposed within the cavity of the beam and under pre-load in engagement with the cover and the base wall, wherein the sensing package comprises a piezoelectric element and a guide plate, wherein the guide plate comprises a first planar section having an opening therethrough and accommodating placement of the piezoelectric element therein, the first planer section extending radially to a guide plate second section that extends axially away from the first section;
wherein the base wall includes an aperture extending therethrough from a mounting surface to the cavity, the aperture configured to receive a fastener therethrough to secure the sensing package within the cavity, and wherein 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.
