The loadcell live idler platform scale has an idler to support a conveyor belt and a frame on which the rollers are mounted. The weighbridge has four load cells connected perpendicular to each end of the frame, strain gauges to receive deflections from each pair of load cells, a speed detector for the material passing upon the conveyor, and a controller for converting the signals of the strain gauges and the speed detector to the desired weight and volume data along with calibrating the scale. Beneath the idler, the scale has a calibration weight resting in a tray. Two cables, attached to the idler and its mounts, suspend the calibration weight and an activator raises and lowers the calibration weight. The calibration weight and activator are generally cylindrical and parallel to the longitudinal axis of the idler.
