Measuring the wear of high-speed railway lines

In order to detect the wear on high-speed railway lines, special measurement wagons inspect the tracks. The measurement wagon contains two optoNCDT 1900 laser displacement sensors. These measure the distance to the track at a high measuring rate. Standard models with a small laser spot detect chipping and defects with high resolution. This determines wear, chipping and slippage.

optoNCDT LL sensors with a small laser line compensate for small irregularities and generate smoothed measurement value curves, which are used to determine the longitudinal trend. Robust optoNCDT 1900 sensors offer high measurement accuracy and are hardly affected by fluctuating reflections and ambient light.
