Planarity inspection of rails

optoCONTROL laser micrometers are used to selectively check railway tracks for flatness and deflection. These are integrated in a test trolley and detect the track at three points with high accuracy, regardless of the condition of the track surface. Depending on the requirements of the measurement task, the distance between the micrometers can be varied. The optoCONTROL 2520 laser micrometer can also be used for different variation depths. Depending on the requirements, models with measuring ranges of 46 and 94 mm are available.
