FIELD: machine building.
SUBSTANCE: invention relates to control devices for monitoring turbine rotors. Invention discloses a control device for monitoring turbine rotor, method of monitoring turbine rotor, turbine stage, turbine engine. Proposed control device comprises acoustic sensor and acoustic waveguide for communication of said acoustic sensor with reading point close to said turbine rotor; acoustic sensor is designed to detect the sound waves of pressure oscillations caused by pressure differences between sides of low and high pressure rotor blades, as far as they are moved past, near the said point reading.
EFFECT: enabling monitoring of turbine rotors, which have a large number of blades.
