Claim:
1. A load cell residual fatigue life estimation system, comprising: an in-service load cell adapted to have loads applied thereto and configured, in response to the applied loads, to supply load cell output signals representative thereof; first memory having stored therein fatigue life reference data associated with a test load cell; second memory having stored therein a predetermined number of data storage bins, each data storage bin representative of a predefined value range of peak loads applied to the in-service load cell; and a first processor coupled to receive the load cell output signals and configured, upon receipt thereof, to: a second processor in operable communication with the first memory and the second memory and configured to (i) calculate a number of load cycles of the in-service load cell based on the detected peak loads stored in each of the data storage bins and (ii) calculate an estimate of the residual life of the in-service load cell from the fatigue life reference data and the calculated number of load cycles of the in-service load cell.
