Conveyor curvature
Vertical curvature (varied heights on one belt) is common in conveyor design, but creates
difficulties for belt scales if not dealt with correctly. The curvature, whether concave (internal) or
convex (external), disturbs the idler alignment, if the scale is installed in the area of curvature.
The concave curve tends to lift the belt off of the idlers in the area of curvature as belt loading
decreases, adversely affecting the zero calibration.
Note
Avoid locating the scale within the tangents of scale curvature.
