Abstract
A weigh scale for a variable inclination conveyor includes an idler or other support for part of an upper belt run of the conveyor, the support being associated with sensors for determining loadings applied to the belt run perpendicular to the direction of the conveyor, and a compensating unit receiving the sensor output calculating the weight of material on the conveyor causing the loading, the unit including a clinometer, and a computing device for causing the sensor output to be modulated by the secant of the angle of the conveyor to the horizontal as sensed by the clinometer.
Claims4
A conveyor weigh scale comprising a weigh bridge supporting a portion of the run of moving conveyor belt and secured to structure for supporting same at a range of different inclinations, said weigh bridge providing an output signal proportional to that component of said belt portion which is perpendicular to its direction of movement, a clinometer secured to said supporting structure and providing an output related to the inclination to the horizontal of said structure and thus said belt portion, and computing means receiving said clinometer signals and modulating said weigh bridge output signal therewith to maintain said weigh bridge output signal in constant proportion to the weight of said material.
