ABSTRACT:
A device for measuring displacement and force comprises two masses of material linked together by a parallel beam linkage which permits displacement of one mass relative to the other in a single direction. The displacement or force input to be measured is applied to one of the masses in the allowable direction. The displacement of the masses with respect to each other is sensed by a sensor. In a preferred embodiment, the sensor comprises a Hall effect sensor attached to one of the masses positioned between two magnets attached to the other mass. Movement of one mass relative to the other changes the magnetic field around the Hall effect sensor. The change is sensed by the Hall effect sensor.
