ABSTRACT:
A single beam force transducer has a beam characterized by a thickened central portion and tapered outward portions. The support members of the transducer are thickened and are thus stiffer while the isolator masses are shortened. These critical configuration changes raise the undesirable "tuning fork" resonant frequency of the beam supporting structure far above that of the beam and ensures that the isolating structure behaves as a rigid body.
