ABSTRACT:
A force transducer producing two output signals having different proportionalities to the magnitude of a force applied to a force receiving platform cantilevered from a base through a C-shaped flexure producing a displacement of the platform proportional to the magnitude of the applied force, a first LVDT (Linear Voltage Differential Transformer) having a movable armature directly connected to the force receiving platform generating a first output signal proportional to the displacement of the force receiving platform and a second LVDT having a movable armature connected to the force receiving platform through a motion multiplying linkage generating a second output signal having a different proportionality to the displacement of the force receiving platform.
