NON-LINEARITY OF SENSORS AND DYNAMIC CALIBRATION |
|---|
| Thomas Bruns |
- Abstract:
- Sensors for the dynamic measurement of mechanical quantities or motion quantities are sometimes subject to a non-linear input-output characteristics. In the case of calibration this may result in deviations of classical calibration results using different methods or different ranges.
The contribution is analysing the effects of non-linear sensor behaviour based on a virtual acceleration sensor. With a known mathematical sensor model and numerical simulations some typical effects are described by example and a simple measurement procedure is proposed to analyse and quantify an unknown non-linearity. The effectiveness of the proposal is demonstrated by a simulated comparison with other methods and the known ”true” non-linearity. - Keywords:
