Fitting of our steering sensor CLSx at the example of BMWs. When you start the movie, connect to Vimeo.com (privacy policy)

The innovative CLSx steering sensor sets new standards in terms of size, ease of operation, resolution and accuracy of measured values. It is placed between the steering column and steering wheel, while retaining all the functionality of the original wheel.

The CLSx records torque, steering angle and steering angle speed with extreme precision. Additionally, accelerations in the center of the steering column in the x, y and z directions as well as the rotational acceleration are recorded. For maximum interference suppression, the measurement data is digitized with a resolution of 16 bit (internal: 24 bit). Combined with the innovative design of the sensor device, this results in unprecedented torque measurement accuracy of 0.1% FS.

Features

  • Ultra-slim sensor device for seamless integration with minimal steering column extension
  • All functions of the original steering wheel are retained
  • Measuring torque range ±100 Nm
  • Angle measurement range ±1440°
  • Rotational speed measuring range ±1000°/sec
  • Acceleration in x, y, z direction
  • Rotational acceleration

Both analog and digital interfaces (CAN, Ethernet) are available on the Receiver Control Unit for data output and parameterization. The integrated 2.83″ color display (320 x 240 px) shows all measured values online in actual physical quantities.
