FIELD: measurement of dynamic deviations of blade faces of turbo-machine from normal at identification of number of each blade. SUBSTANCE: device includes pulse peripheral sensor mounted in turbo-machine housing above trajectory of motion of blade faces, mark sensor, square blade pulse shaper, square pulse shaper, clock pulse generator, time interval measuring unit, OR gate, shift register and computer. Proposed device is characterized by extended functional capabilities ensuring study of dynamic state of turbo-machine blades and warning on state of blade close to emergency in case of indication of fatigue strength or defects of blades. Provision is also made for connection of device to automatic control system of engine. EFFECT: extended functional capabilities. 4 dwg
