| Summary: | An innovative calibration model of weight measuring load cells was developed for The Specialized Industries Company in Jordan. Raw material is stored in two 30 meter high silos. Each silo can hold up to 90 tons of grains. The weight of the grains in each silo is measured using a 4-load cell configuration. The weight reading was lower than the actual weight and the difference reached a few tons. It was vital to develop a technique for obtaining accurate weight measurements. Towards this end, a well planned experiment was conducted for collecting load cell data during repetitive silo filling and emptying. The data was analyzed thoroughly and useful patterns were identified. A calibration model which uses the load cell reading only to infer the actual weight was obtained. The model was validated with real weight data and it gives accurate readings within a few hundred kilograms.
