Abstract
The moment sensitivity of shear beam transducers is mechanically compensated to make such transducers relatively insensitive to load applications which are off-center relative to an optimal point of load application. Such shear beam transducers have a free end forming a load application section, a mounting section, and a fillet located substantially where the sections merge. The compensation is made by providing the fillet initially with a larger radius than the final compensating radius. The compensation is made by gradually changing the fillet radius until the transducer output shows substantially no difference between the measurement resulting from applying a defined load in the optimal loading point and the measurement resulting from applying the same load off-center the optimal loading point whereby the transducer becomes substantially insensitive to such off-center load applications.
