Distortion gauge and force converter using the same

摘要

PROBLEM TO BE SOLVED: To provide a strain gauge equipped with a shorting adjustment pattern part that reduces the effect of a resistance value change due to strain deformation.SOLUTION: There is provided a strain gauge equipped with a loopback pattern part for strain detection and a shorting adjustment pattern part for resistance adjustment, where the shorting adjustment pattern part includes a plurality of resistance wirings in which resistors are arranged in parallel and selectively cut off, each resistance wiring forming a line symmetrical shape, with a perpendicular of a line segment linking their start and end points as an axis of symmetry, having at least partly a component in a direction that intersects each of the line segment linking the start and end points and the axis of symmetry, the strain gauge being arranged in a strain body so that the direction of shearing force applied to the strain body and the axis of symmetry are parallel.SELECTED DRAWING: Figure 1
