Zusammenfassung:	A system and method for estimating the residual fatigue life of a load cell includes storing, in a memory, fatigue life reference data associated with a test load cell. A predetermined number of data storage bins are provided. Each data storage bin is representative of a predefined value range of peak loads. Peak loads applied to an in-service load cell are detected, and each is stored in an appropriate one of the data storage bins. A number of load cycles of the in-service load cell are calculated based on the detected peak loads stored in each of the data storage bins. An estimate of the residual life of the in-service load cell is calculated from the fatigue life reference data and the calculated number of load cycles of the in-service load cell.
