Abstract, Prior vibrating beam accelerometers are subject to errors caused by differential thermal expansion between the vibrating beams and other accelerometer components. This problem is overcome by the present accelerometer that comprises a housing (32), a proof mass (30) support means, (34,36) for mounting the proof mass with respect to the housing, and first and second force sensing elements (38 40). The force sensing elements are connected between the proof mass and the housing such that differential thermal expansion or contraction between the force sensing elements and the proof mass, support means and housing results in rotation of the proof mass about a compensation axis (CA) …
