ABSTRACT:
A scale for weighing material as it is transported along a movable conveyor is disclosed as including a pair of wheatstone bridge load cell assemblies which are mounted subjacent and across a roller assembly forming a part of the conveyor. The entire scale assembly is mounted between the framework stringers of the conveyor by a pair of inexpensive IPS pipes. In accordance with the invention, the entire scale assembly is mountable on differing width conveyor systems simply by changing the lengths of the IPS pipe portions of the scale framework so as to fit the frame on the respective stringers. Input into the dual wheatstone bridge circuits is fed into a computer, along with input relating to the speed (displacement) of conveyor movement to provide data needed for calculating a number of potential output figures. Remote display and monitoring of numerous such conveyor scales provides for ease of monitoring multiple conveyor systems.
