  • System for compensating for creep and hysteresis in a load cell
    Patent number: 7742891
    Abstract: A method of compensating for hysteresis in a load cell, by: (a) pre-calibrating a load cell by: measuring load cell deflection under progressively increasing loads; determining a first set of coefficients correlating the deflection of the load cell to the measured load under the progressively increasing loads; measuring load cell deflection under progressively decreasing loads; determining a second set of coefficients correlating the deflection of the load cell to the measured load under the progressively decreasing loads; and then (b) compensating for hysteresis in the load cell, by: selecting the first set of coefficients if the load on the load cell has been progressively increasing, or selecting the second set of coefficients if the load on the load cell has been progressively decreasing; and applying a formula using the selected first or second set of coefficients to the measured load cell deflection at the particular load, thereby determining an accurate load cell deflection, and thus compensating for h
