Sensor intended to be embedded in a layer of cement material of a pavement and security system including said sensor

摘要

A sensor adapted to be embedded in a layer of cement material of a pavement to detect pressure thrusts acting on said pavement. The sensor includes: a plate-like transducer; a base structure including a container fitted with a chamber such as to house said transducer and a layer of protective material defined between a surface in contact with said transducer and an opposite free surface; a pressure plate including a force transferring portion and a force receiving portion which projects compared to said force transferring portion, the force transferring portion including one end portion facing the force receiving portion and one opposite end portion. The force transferring portion is such as to distance the force receiving portion from the free surface so as to define between the force receiving portion and the free surface a region which can be filled at least in part with the cement material of the layer of cement material.
