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).
