Current CVT systems use hall sensors or pressure sensors for various measurements. Challenges can arise over time due to metallic debris attracted by the use of permanent magnets, which eventually cause sensors to lose accuracy.

Advantages of Methode Eddy Current Sensors :

  • No use of magnets necessary which attract metallic debris
  • Immune to magnetic fields
  • Improved sensor lifetime
  • Can utilize existing components of the transmission to measure

Applications in the CVT:

  • Drive & Driven Pulley Speed Sensing
  • Variator Position Sensing
  • Hill Assist Sensor for detecting speed and direction
  • Park Rod Sensing
  • Valve Spool Sensing (PRND)
  • Solenoid Sensing
  • Belt Movement Sensors
