Abstract: A sensor assembly includes an annular target body disposed about a rotatable member outer surface and an annular angular position indicator with at least one angular position index corresponding to an angular position of the member. Radial displacement sensors are spaced circumferentially about the axis and radially outwardly from the target body outer surface. A reference sensor is disposed circumferentially between two of the radial displacement sensors, has an inner end spaced outwardly from the target body surface by a first spacing distance, and is configured to detect the target body. An angular displacement sensor is spaced axially from the reference sensor and has an inner end spaced outwardly from the position indicator surface by a second spacing distance. The angular sensor is located such that the second spacing distance is generally equal to the first spacing distance and such that the position index passes the sensor inner end.
