ABSTRACT:
A weighbridge unit for use in a conveyor weigh scale has a support for part of the conveyor belt, such as a trough or one or more idlers, a bridge carrying the support, and load cells formed by cantilever strain gauge bridge units supporting the ends of the bridge, the electrical outputs of the bridge units being summed to provide a weighbridge output signal. Cantilever arms of the load cell bridge units preferably extend in the direction of movement of the belt.
