Abstract: An induction sensor measures vibrations of a turbo-machine fan blade. The induction sensor comprises a magnet and an induction coil wound upon the magnet parallel to the lines of the magnetic field generated by the magnet.

Abstract: A method is disclosed of measuring vibrations on turbo-machine rotary turbine blades utilizing an induction sensor at high temperatures. A set of magnets produces a magnetic field which results in a measurement signal generated in the sensor's coil which then can be interpreted to measure the vibrations.

Abstract: An induction sensor measures vibrations of a turbo-machine fan blade. The induction sensor comprises a magnet and an induction coil wound upon the magnet transversely to the lines of the magnetic field generated by the magnet.

Abstract: The invention relates to a method of a continuous determination of an instantaneous position of an impeller blade tip (5′) in a rotor turbine machine, particularly in a turbine impeller (6) in a turbojet engine during its operation in a real condition in order to obtain a current information on a technical state of the blade (5). In a selected place of an housing (7) of a rotor turbo machine, in a movement plane of impeller blade tips (5′), it is arranged in a stable manner at least one microwave antenna (3) with an aperture shape (4) which is consistent with an internal surface of an housing (7). The microwave signal (11), which is produced by a microwave homodyne system, is emitted, and then received, through a microwave antenna (3). The output signal (9) from that system, which carries out information on each instantaneous position of an impeller blade tip (5′) in relation to an antenna aperture (4), is converted by an electronic system, and then it is read.

Abstract: The invention solves the problem of generation and homodyne detection. Its main application refers to generation and reception of microwave signals during instantaneous measurement of position and shift of mobile elements especially of rotor units of working turbo-machines during true-time operation. The method based on the selection of equal value of both electrical channels between shunt arm in waveguide T-connection and generation diode in one collinear arm and in the second collinear arm between the same shunt arm and detection diode. The system contains generation diode seating connected through waveguide T-connection with detection diode seating.
