Latest Patents

Haggstrom's latest patents include innovations that address off-center loading errors in compression column load cells. His first patent describes a simple and inexpensive electrical compensation method for off-axis and off-center loading sensitivity. This is achieved by incorporating a pair of compensation strain gauges in series with each of the main strain gauges in the load cell. The compensation gauges are strategically connected in series with their associated main strain gauge, forming a bridge arm in a strain gauge bridge. This design allows for effective loading sensitivity compensation in both conventional fixed axis load cells and Rocker Pin load cells.

His second patent further elaborates on the same concept, emphasizing the arrangement of compensation gauges crosswise to each associated main strain gauge. This innovative approach enhances the performance of compression column load cells, ensuring accurate measurements even under varying loading conditions.
