Abstract:
An improved technique for mounting a coil to a paddle in a force rebalance accelerometer so as to provide relief from temperature induced strains without increasing the mass of the proof mass. The coil is mounted to the paddle at a plurality of mounting sites on the paddle, at least one of which is connected to the paddle by suspension means compliant for movement in the plane of the paddle. In a preferred arrangement, three mounting sites are used, two of which are moveable towards and away from the third, fixed mounting site.
