ABSTRACT:
A force transducer for producing an output signal in proportion to the magnitude of an input force wherein an equal and opposite force is produced by a flexure assembly comprised of a compound leaf-spring flexure having opposed outer sections, anchored in and cantilevered from a fixed and a movable base respectively, which gradually decrease in cross-sectional area to a thin middle section wherein the movable base is constrained to linear displacement from a null or neutral position by having the force applied along a line normal to and passing through the center of the thin middle section and transmitted to the movable base through a rigid connection. A modified form of flexure assembly is disclosed comprised of parallel compound flexures each having a thin middle section and opposed outer sections which are anchored in and cantilevered from a fixed common base and a movable common base.
