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.
