Abstract

A feedback device (204; 204') or phonic wheel is coupled to rotate with a rotating component of an aircraft engine (10). The feedback device (204; 204') comprises a body (302; 302'; 606) having cavities (406) defined therein and circumferentially spaced thereabout, each cavity (406) configured to receive therein a position marker (306; 306'), the body (302; 302'; 606) made of a non-ferromagnetic material and the position markers (306; 306') comprising a ferromagnetic material. A sealing member (304; 304') is configured to be secured to the body (302; 302'; 606) for retaining the position markers (306; 306') within the cavities (406). At least one sensor (212) is positioned adjacent the feedback device (204; 204') and configured for producing, as the feedback device (204; 204') rotates about a longitudinal axis (A) with the rotating component, at least one sensor signal in response to detecting passage of the position markers (306; 306'). A processing unit (220) is communicatively coupled to the at least one sensor (212) and configured to determine a rotational speed of the rotating component from the at least one sensor signal received from the at least one sensor (212).
