Abstract / Hauptanspruch
A sensor assembly (10) includes an annular target body disposed about a rotatable member outer surface or integrally formed therewith and an annular angular position indicator (14) with at least one angular position index (22) corresponding to an angular position of the rotatable member. Radial displacement sensors (16) are spaced circumferentially about an axis (A c) and radially outwardly from the target body outer surface (13). A reference sensor (18), which 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 (20) is spaced axially from the reference sensor (18) and has an inner end spaced outwardly from the position indicator surface (15) by a second spacing distance. The angular displacement sensor (20) is located such that the second spacing distance is generally equal to the first spacing distance and such that the position index (22) passes the sensor inner end during rotation of the rotatable member.
