Abstract
A magnetic circuit assembly for an accelerometer includes an excitation ring that includes a base portion defining oppositely facing first and second sides, a ring portion extending from the second side of the base portion to define a ring recess, a first metallic inlay recessed into the first side of the base portion in which the first metallic inlay includes a material different than that of the base portion, a second metallic inlay recessed into the second side of the base portion in which the second metallic inlay includes a material different than that of the base portion, and a magnet received within the ring recess and attached to the second metallic inlay.
