ABSTRACT:
A multi-axis load cell including a housing having a circular opening, a hub member having three radially extending arms is supported within the housing by a plurality of spring members and has a cylindrical portion located in the circular opening. A ring member forms a part of the housing and is provided with three circumferentially spaced posts each of which supports a screw connected to a spring member. The screw in each post is adapted to apply a radial force to the associated spring so as to achieve concentric positioning of the cylindrical portion relative to the circular opening. The housing also carries an adjustable force applier that engages the ring member for rotating the latter for achieving mechanical zero adjustment of arms formed on the hub member.
