ABSTRACT:
A system for validating a payload weight measurement for a machine includes a pressure sensor configured to generate a pressure signal indicative of an actuating fluid pressure associated with a fluid cylinder operatively coupled to a work implement of the machine. An extension sensor is configured to generate an extension signal indicative of an extension of the fluid cylinder. The system also includes a controller configured to monitor the pressure signal and the extension signal to determine a plurality of actuating fluid pressure values and corresponding extension values associated with the fluid cylinder while lifting a payload of unknown weight with the work implement. The controller is also configured to compare the plurality of actuating fluid pressure values and the corresponding extension values to at least one predetermined pressure versus extension curve and to determine whether an accurate weight value may be assigned to the payload based on the comparison of the plurality of actuating fluid pressure values and the corresponding extension values to the at least one predetermined pressure versus extension curve.
