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. The compensation is made by gradually increasing the depth of a load application hole in the transducer. The load application hole extends in the direction of a load application axis and its depth is increased until said moment sensitivity becomes substantially zero. In other words, the load sensitivity becomes substantially independent of the location of the point of load application. A further linearization of the moment sensitivity is accomplished by placing inserts into the load application hole.
