ABSTRACT:
An accelerometer comprising a proof mass assembly that includes a reed suspended from a support and a cylindrical coil mounted to the reed by a mounting system that minimizes errors due to thermal stress. The mounting system comprises at least three mounting elements. Each mounting element has first and second ends, and a resilient intermediate portion. The first end of each mounting element is connected to the coil, the second end of each mounting element is connected to the reed, and the intermediate portion of each mounting element provides a low resistance to relative movement between the coil and reed in a radial direction, and a high resistance to relative movement between the coil and reed in directions normal to the radial direction. The reed preferably comprises fused quartz, and the mounting system preferably comprises a fused quartz base mounted directly to the reed and connected to the second end of each mounting element. The coil may be mounted on a coil form that is connected directly to the first end of each mounting element.
