ABSTRACT:
A load cell for measuring forces applied thereto including an adjusting mechanism for off center load adjustment is disclosed. The load cell comprises a substantially parallelogram structure having a moving section on one side and a fixed section on the opposite side. Upper and lower strips extend between and connect the fixed and moving sections. Flexjoints are located at approximately the juncture of each of the strips and the sections, the flexjoints being adapted to flex in response to the force exerted thereon and facilitate transmission of the force to the transducer portion of the load cell. An adjusting mechanism for off center load adjustment is positioned on the load cell and includes both a vertical and horizontal adjusting mechanism that are adapted to alter the position of a first flexjoint adjacent to the adjusting mechanism relative to the position of a second flexjoint.
