When a structure is subjected to an external stimulus such as pressure change, load, loss of material or temperature variation; The materials react and trigger the release of energy in the form of tension waves, which propagate to the surface and are recorded by sensors and an acoustic acquisition system, allowing not only the problem to be detected, but also its spatial location. Well, at Matgeo.spa we have the equipment and experience in detecting these anomalies, which help predictive maintenance in industrial processes that we put at your disposal.
