First Claim
Patent Images
1. An accelerometer, or the like, comprising:
- a housing;
a proof mass mounted in the housing for reciprocal movement with respect to a sensing axis;
an elongated vibrating beam resonator; and
means coupling the ends of the resonator to the housing and to the proof mass respectively so that the axis of the resonator is parallel to the sensing axis, said last-named means including relief means for releasing said resonator when the force along said sensing axis exceeds a particular threshold.

Abstract
A vibrating beam accelerometer is provided which includes a quartz vibrating beam resonator as aa force transducer, and which also includes resiliently biased relief arms which release the quartz beam should the acceleration forces become excessive. The relief arms serve to protect the beam against overload forces, and to permit the proof mass of the accelerometer to be sufficiently high as to enable the accelerometer to measure accelerations in a relatively wide range as compared with the range capabilities of prior art vibrating beam accelerometers.
