Abstract
A strain gage for measuring an applied force or weight. The strain gage includes a substrate having a tapered center section that is adapted to be stressed in response to the applied force. A strained resistor is mounted on the center section of the substrate. A wing section is attached to the center section. The wing section is adapted to be not stressed by the applied force. An unstrained resistor is mounted on the wing section. A terminal section is mounted to the center section and the wing section.
