A system and method configured to measure applied force and pressure on a load cell. The system includes an axial force pressure transducer having a hollow cross section comprising at least two strain sensitive regions, and a plurality of strain sensors connected to the at least two strain sensitive regions, wherein applied force and pressure is calculated based on strain measurements using mathematical formulae. A method of calibration of the axial force pressure transducer using known applied force and pressure measurements to calculate a calibration matrix reflecting the strain sensitivities of the at least two strain sensitive regions.

A load cell structure for receiving strain gages to monitor applied torsional forces wherein the opposing force-receiving ends have a plurality of sensing beams spaced about an axis of rotation. Limit posts located between the ends each have a discontinuity therein that includes a U-shaped gap to limit relative rotation about the axis and thereby providing overload protection.

Load cell for monitoring torsion and having overload protection

Load cell for monitoring torsion and having over load protection

A load cell having overload protection wherein a central cantilever beam is provided between the sensing beams in the load cell structure and is bounded by slots of narrow gap width. When an excess load is applied, the load cell structure is deformed and contacts the cantilever beam to transfer the load thereto. The gap width determines the amount of applied load which initiates the protection.
