  • Patent number: 4566340
    Abstract: A force transducer angularly adjustable about an axis for producing an output signal proportional to the magnitude of an input force. A signal output member, cantilevered from a base through a spring flexure, is provided with a spindle, the center of which lies in the axis, receives the input force. The moment impressed on the flexure by the input force and the resulting displacement of the output signal member from a null or no-load position is a function of the magnitude of the input force and the angular adjustment of the transducer about the axis. Such angular adjustments can be made in-situ without disturbing the spatial position of the spindle.

  • Patent number: 4487079
    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.
