WIM systems can employ various types of sensors for measurement. The earliest WIM systems, still used in a minority of installations, use an instrumented existing bridge as the weighing platform. [38] [39] Bending plates span a void cut into the pavement and use the flexure as the wheel passes over as a measure of weight. Load cells use strain ...

There are weight detecting devices in the roadway itself. A driver may get a red light. On these occasions, the truck must pull into the weigh station for the normal weigh-in procedure. The most common reason a truck is "redlighted" is a weight problem, or a random check.

A strain gauge sensor measures the deformation of the elastic element, and the output of the sensor is converted by an electronic circuit to a signal that represents the load. Capacitive strain gauges measure the deformation of the elastic material using the change in capacitance of two plates as the plates move closer to each other.
Data are acquired from various sensors for use in post-test analysis of pavement properties. Deflection sensors are used to measure the deformation of the pavement in response to the load pulse. In some FWDs the magnitude of the applied load pulse is an assumed constant value determined by system design; in others the force is measured by load ...
