Manual Profile Measurement of Rails via 2D/3D Profile Sensors on Trolleys
Regular measurement of tracks is necessary in the rail industry to ensure the safety of rail transport. Trolleys are used for short sections of track for this purpose. In manual mode or on a small locomotive, they use four 2D/3D profile sensors to check the rail geometry for bare or rusty steel with micrometer precision. Via laser triangulation, the sensors provide values for width, inclination, irregularities or damage. The sensors reliably measure in all weather conditions, high levels of ambient light, such as sunlight, and any temperature.
