ABSTRACT:
An accelerometer includes a cantilevered pieozelectric beam mounted to a surface inside a fluid filled chassis with a proof mass attached to the beam's free end. Surface skimming bulk wave delay lines are mounted on opposing major surfaces of the beam and are responsive to strain induced therein by acceleration of the proof mass.
