ABSTRACT:
A force rebalance accelerometer includes a magnetic assembly designed for improved scale factor performance and producibility. The magnetic assembly excitation ring includes slots. The slots are defined by an inner edge of the upper surface of the excitation ring and are separated by an upper surface portion or tongue intermediate the slots which extends away from the outer edge of the upper surface and toward a magnet received within the interior portion of the excitation ring.
