ABSTRACT:
A universal belt scale for measuring the weight of material being transported on a conveyor belt includes a pair of independent weigh beams, each having a cantilevered deflection section, the beams being uniquely mounted to extend inwardly of the stringers in such a way that the universal belt scale can be used with a variety of belt widths and belt loading situations. The neutral axis of the deflection section is preferably positioned in substantially the same plane as the roll supporting the belt. Alternative embodiments of a mounting allows the position of the weigh beam to be adjusted relative to the idler assembly. Alternative embodiments of an adjustable pivot allow the full scale capacity of the belt scale to be varied. The universal belt scale may also include varying the sensitivity of the weigh beam, for more accurate weighing.
