FM5-BT | Camera Bluetooth

The FM4-LO contact wire measuring device is specially designed for static point measurement of contact wires. The laser beam of the FM5 determines the position of the catenary in relation to the track center as well as from the top of the rail.

This enables you to measure quickly and easily the:

  • Contact wire height and stagger (zig-zag)
  • Messenger wire height and stagger
  • Distance between pole leading edge and track center
  • Bridge and tunnel heights, height of crossing power lines
  • With accessories: superelevation (tilt/angle)


    • Project planning and construction of overhead line systems
    • Regulatory and maintenance tasks on catenary and contact lines
    • Calibration and control and of continuous, dynamic geometry measurement methods
    • Optimized for mobile use in light and long-distance rail


    In combination with the measuring bar, the measuring device can measure contact wire stagger on track gauges in the range of 750 - 1676 mm. The measurements can be performed quickly and in any weather condition.
