Method and apparatus for assessing the residual life of a sensor unit
First Claim
1. A method for assessing the residual life (R) of a sensor unit, which is fitted on a cyclically operating machine and is intended for a certain number of loading cycles (B), comprising the steps of:
- detecting loading of the sensor unit by the machine in a loading cycle (B),determining a damage factor (S) for the sensor unit as a function of the detected loading by means of a damage model of the sensor unit for the loading cycle (B), andweighing the loading cycle (B) with the respectively determined damage factor (S) in order to assess the residual life (R).

Abstract
The life of a sensor unit is very strongly dependent on the loading of the sensor unit during use. The life of a sensor unit is generally specified in a number of loading cycles, however, which does not take into consideration the loading of the sensor unit. The invention therefore specifies a method and apparatus for assessing the residual life of a sensor unit which takes into consideration the actual loading of the sensor unit and therefore the residual life of the sensor unit can be estimated more precisely by virtue of a damage factor (S) being determined for the loading of a loading cycle (B) and the loading cycle (B) being weighted therewith.

10. An apparatus for assessing the residual life (R) of a sensor unit comprising:
- a sensor unit which is fitted on a cyclically operating machine and intended for a certain number of loading cycles (B), and an assessment unit to determine a damage factor (S) as a function of the loading of the sensor unit for a loading cycle (B) using a damage model, and to weigh the loading cycle (B) with the determined damage factor (S) in order to assess the residual life (R).
