EP 1120494 A UPAB: 20011113 NOVELTY - The measuring device uses a distance measuring head (12) with an electromagnetic radiation source and a detector for the radiation (16) reflected from the track rail surface (14), evaluated for providing the characteristic surface roughness of the track rail. DETAILED DESCRIPTION - An acceleration sensor (13) is attached to the measuring head for measuring the acceleration component perpendicular to the rail surface, which is integrated for providing a position variation signal combined with the rail distance signal before Fourier transformation. USE - The device is used for measuring the surface roughness of track rails in a rail track network. ADVANTAGE - The device allows measurement of the track rail surface roughness at relatively high travel speeds.
