A feedback device is coupled to rotate with a rotating component of an aircraft engine. The feedback device comprises a body having cavities defined therein and circumferentially spaced thereabout, each cavity configured to receive therein a position marker, the body made of a non-ferromagnetic material and the position markers comprising a ferromagnetic material. A sealing member is configured to be secured to the body for retaining the position markers within the cavities. At least one sensor is positioned adjacent the feedback device and configured for producing, as the feedback device rotates about a longitudinal axis with the rotating component, at least one sensor signal in response to detecting passage of the position markers. A processing unit is communicatively coupled to the at least one sensor 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.
