Abstract: Apparatus for generating a belt tare compensation signal including a load cell in operative contact with a feed conveyor belt dividable into N equal segments. The output of the load cell is strobed each time the conveyor belt advances one sampled and a pulse train representative of the output of the load cell is generated. The pulse train is applied to a pulse counter if the output of the load cell is greater than a predetermined value and is applied to a minus counter if the output of the load cell is less than a predetermined value. At the end of a single revolution of the conveyor belt, a signal representative of the difference between the count in the plus and minus counters is generated. This signal is divided by N so as to generate a belt tare compensation signal which is representative of the average output of the load cell during a single non-loaded revolution of the conveyor belt.
