Railway Speed Sensors


Application highlight – torsional vibration detection


Reliable, accurate and fast torsional vibration detection is key to increase traction performance, wheel set lifetime and safety. BPIK signals enable torsional vibration detection with ultimate dynamics and precision, by unsurpassed signal quality and robustness, high resolution and zero backlash. This enables reduced wear, increased traction and improved passenger comfort.

Overview of applications:

  • Traction control
  • Torsional vibration detection
  • Wheel slide protection
  • Train control
  • Bogie and wheel condition monitoring
  • Juridical recording
  • Drive information system
  • Hot box detection
  • Bogie hunting and derailment detection
  • Cold movement detection (CMD)
