FIELD: measurement technology.
SUBSTANCE: group of inventions refers to the region of the rotating blades, in particular to the region of characterization of vibrations to which such blades are subjected when they are in rotation. Gas turbine engine assembly includes a housing and a movable shovel wheel rotating in the housing and comprising at least one blade having a vertex opposite the housing. Vertex contains a magnet, and the body contains an electrical conductor, which is configured to generate, between its terminals, an electric voltage signal induced by a magnet opposite the vertex and characterizing the vibration, acting on the vertex of the blade during the rotation of the blade wheel.
EFFECT: improving the accuracy of measuring the vibration of a gas turbine engine blade.
