ABSTRACT:
Various improvements are disclosed for enhancing accuracy in a system for weighing rolling railcars in order to remedy previous factors contributing to weighing inaccuracies. In a system operative by means of a plurality of longitudinally spaced sensors secured to a predetermined length of relatively unsupported track for measuring track stresses imposed by a passing railcar, accuracy of the weighing result is enhanced by several structural improvements. Included among the improvements is a substructure underlying the live rail that eliminates yield at the fulcrum location from the supported to the unsupported rail. Also included are tandem scales operative sequentially in the path of motion for obtaining readings at selectedly different locations about the circumference of the wheel and from which an averaged signal is obtained for determination of car weight. Signal compensation is also provided for both changes in track temperature and drift in instrument calibration.
