ABSTRACT:
Off-center load applications to strain gage pick-ups or transducers are substantially compensated by reducing the off-center load application sensitivity of such transducers. This is accomplished by providing the strain gage of the transducer with additional strain gage components which are so located that the effective position of the strain gage device is shifted on its supporting spring body. Thus, although the strain gage device remains physically in position on the supporting spring body, the center of the coordinate system which defines the ordinate of the system can be shifted in any one of the four directions of the system. If the spring body is equipped with a single strain gage only then the point of load application should lie upon the ordinate of the coordinate system what can be achieved by that shifting. If the spring body is equipped with more than one strain gage then the symmetry of the whole strain gage circuitry can be improved by shifting of the respective strain gage coordinate systems.
