ABSTRACT:
An accelerometer with a pivoting beam to accommodate differential thermal effects. The accelerometer measures acceleration along a sensitive axis, and comprises a housing, a proof mass, support means and a coupling assembly. The support means mounts the proof mass with respect to the housing. The coupling assembly is connected to the proof mass and housing, and comprises a beam and first and second force sensing elements. The beam is mounted for pivotal movement about a compensation axis normal to the sensitive axis. The first and second force sensing elements are connected to the pivot member at spaced-apart connection points on opposite sides of the compensation axis from one another, such that an acceleration along the sensitive axis results in respective compression and tension forces on the force sensing elements, and such that differential thermal expansion results in rotation of the beam about the compensation axis.
