POSITAL FRABA has added a new communications interfaces for its innovative Dynamic TILTIX series – making it even easier to use these rugged instruments in mobile machinery and heavy commercial vehicles. Now available with either CANopen or SAE J1939 interfaces , these acceleration-compensated tilt sensors are able to deliver accurate measurement under the harshest operating conditions, including rapid motions, shock and vibration loadings.

  • Compensation of External Accelerations
  • Now Available with CANopen or SAE J1939
  • Clean Measurement During Dynamic Movements
  • Optional Output of Acceleration and Rate of Rotation
  • Well Protected up to IP69K
  • Compact and Robust Die-cast Housing with Integrated T-Coupler 
  • Wide Temperature Range from -40 to +85°C

Innovative Signal Processing Algorithms Reduce Signal Noise

The key to this remarkable dynamic performance is the addition of a second measurement system to the MEMS accelerometers used in conventional tilt sensors. An electromechanical gyroscope system was added to measure rate of rotational in the different axes. This eliminates the central shortcoming of conventional inclination sensors, where sudden accelerations or vibrations cause inertial loads in the accelerometers, adding noise to the output signals – and errors to the tilt angle readings. Signals from the accelerometer and gyroscope are combined by innovative algorithms to filter out the errors caused by acceleration loads so that the actual inclination is reported accurately. “What sounds so simple proved to be very time-consuming and labor-intensive in terms of practical implementation,” emphasizes Tobias Schubert, product manager responsible for POSITAL’s TILTIX inclination sensors. “We invested almost three years in the development of the algorithm alone. We worked extensively with pilot customers to assure ourselves that these instruments would work reliably under the harshest field conditions.”
