Abstract
A device for detecting a rail load fits into a bore of a rail and includes a sensor that generates a load signal under an action of the rail load caused when rail vehicles with wheels travel on the rail and the wheels exert a load onto the rail. The load signal is a measure for the rail load. The sensor includes at least one piezoelectric sensor element that generates electric polarization charges as the load signal.
