Abstract
This force transducer is intended for use in locations where the space available is dimensionally limited in the direction of the active and reactive forces being measured. It is more resistive to forces acting at an angle with respect to those active and reactive forces than the devices of the prior art. It comprises a cylindrical block, usually steel, having a central load bearing portion adapted at one end to oppose a force acting axially of the block, and a peripheral portion concentric with the central portion and adapted at the opposite end to oppose the reactive force. The central portion and the peripheral portion are separated by two arrays of cylindrical holes, with at least three holes in each array, each hole extending parallel to the axis of the block and spaced therefrom. The two arrays of holes define at least three pairs of parallel bridging portions extending between the central load bearing portion and the peripheral load bearing portion. Two strain sensitive elements are mounted on each bridging portion on opposite surfaces thereof, so that two strain sensitive elements are located inside each hole. The strain sensitive elements are connected in a bridge circuit.…
