<p>In a force transducer for producing an output signal proportional to the magnitude of a force applied to a force receiving platform cantilevered from a base through a compound flexure unit, comprising: (a) a c-shaped flexure having a thin, flexible middle section and opposed rigid outer sections engaging, respectively, the opposed surfaces of the platform and base and, (b) an auxiliary flexure spring system comprising parallel spaced apart leaf springs cantilevered, respectively, from the opposed rigid sections joined together at their free ends by a clamp adjustable to vary the effective length of the springs as required to calibrate the transducer to a predetermined force range.</p> |
