ABSTRACT:
A force transducer is formed by utilizing a slender column, having co-extensive opposing flat surfaces, interposed between a fixed member and a member movable toward the fixed member so that the plane of bending will be perpendicular to the flat surfaces. A pair of strain gauges are attached to the opposite flat sides of the column and connected with opposing terminals of a Wheatstone bridge in series through the respective strain gauge and balanced by resistors. The read-out of the bridge indicates the increase or decrease in resistance of the strain gauges which is proportional to the force applied.
