Laser measurement

In-track measuring system IWMS

The IWMS system is a measuring system which is integrated into the track. This system records the profile of each wheel in real time with an accuracy of ± 0.05 mm.The measurement is made while the train is crossing.

The IWMS system uses the wheel profile to calculate all important wheel and axle parameters such as:

  • Wheel flange height and thickness
  • qR dimension
  • wheel width
  • AR dimension
  • hollowness
  • wheel diameter

The IWMS system can be installed inside the depot without modifying the rails.The adaptation to the local space and the special regulations of the individual depots is just as possible as the installation outdoors.
