Scanning of the rail longitudinal section
With the same sensor positioning as for the classification of the wear-and-tear condition, also the longitudinal waviness can be recorded. With the aid of the computer the wave lengths and amplitudes are being determined by Fourier Analysis from the recorded rail surface. The measurement can take place during the rail machining process or during a separate measuring drive. After the measurement, a separate measuring protocol for each section of the track will be prepared.
