Dynamic inclination sensors

The solution for sudden and fast movements

Fusing 3D accelerometer and gyroscope data for uncompromising accuracy

Acceleration-compensated inclination sensors are particularly suited for moving machines and vehicles subjected to sudden movements, shock and vibration, and which rely on a fast response and high signal quality. This type of inclination sensor combines the familiar 3D MEMS accelerometer with a 3D gyroscope.

The accelerometer indirectly measures the inclination (like a static inclination sensor), while the gyroscope determines the rate of rotation.
As mentioned under “Limitations of static inclination sensors”, unintentionally detected external accelerations have a huge impact on the accelerator, but a limited effect on the measured rotation rates of the gyroscope.
Innovative, smart algorithms combine the signals from both measuring principles so that the above-mentioned effects are fully compensated and output without delay.

Dynamic inclination sensors of the JD series with 6 degrees of freedom

The dynamic inclination sensors of the JD series set new standards with regard to signal quality and response characteristics. They use a 3D gyro sensor as well as a 3D acceleration sensor.
A 6-axes IMU (Inertial Measurement Unit) with intelligent sensor fusion filters determines the precise inclination values on this basis. Interference, as may for example occur in mobile applications due to vibrations, impact or starting and braking behaviour, do not falsify the measured values.

Additional functionalities of the dynamic inclination sensor [JDxxxx]

The main purpose of dynamic inclination sensors is to provide stabilised (acceleration compensated) data for tilt angles without the need for configuring any sensor parameters. However, for dynamic inclination sensors with CANopen or J1939 interface, it is also possible to output the acceleration forces (accelerometer) and rotation speed (gyroscope) separately for each of the three axes. These measurements are stored in mappable CANopen or J1939 objects.

  • Monitoring the acceleration force along one or more axes can be used to implement additional functions or safety features on the controller side. The controller can stop the machine when a certain acceleration threshold is exceeded.
  • With the additional information about the rotation speed in z axis, it is, for example, possible to measure the horizontal (yaw-) rotation of the machine and detect the direction of travel of the respective vehicle.
