Abstract
An assembly is provided for a turbine engine. This turbine engine assembly includes a rotating assembly configured to rotate about an axis. The rotating assembly includes an engine component and a phonic wheel. The engine component includes a first material and a plurality of apertures arranged circumferentially about the axis. The phonic wheel includes a second material and a plurality of teeth arranged circumferentially about the axis. Each of the teeth projects axially into a respective one of the apertures. One of the first material and the second material is or otherwise includes non-ferromagnetic material. Another one of the first material and the second material is or otherwise includes ferromagnetic material.
