ABSTRACT:
A vibrating beam force transducer includes a piezoelectric beam structure supported at first and second ends, and an oscillator for inducing a vibration in the piezoelectric beam. To permit adjusting the bias frequency of the beam, an adjustment mass is formed at the center of the beam, the adjustment mass made of piezoelectric material. Part of the adjustment mass can be broken off to adjust the bias frequency. The first and second ends are attached to the a support structure by first and second legs at each end of the beam, the legs having an angle therebetween, thereby forming an A-frame mount.
