Non-contact Displacement Sensors for Automotive Markets

Capacitive non-contact displacement and thin gap sensors have made significant contributions to improving R&D, quality and manufacturing efficiencies for vehicle manufacturers around the globe. This is due to their many advantages such as:

  • Small size, broad range
  • Accuracy in the micron range
  • Displacement measurement up to 1,832°F (1000°C)
  • Immunity to magnetic fields
  • On-vehicle DC modular electronics

Applications range from inserting a 4mm diameter button sensor inside a head gasket to measure precise displacements of the seal while the engine is running to installing HPT-500V sensors into automotive windshield molds to check gaps in-process at 1,472°F (800°C). Our sensing systems are used to test vehicles from economy compact cars to Formula 1.
