  • Device and method for monitoring rotor blades of a turbine
    Patent number: 9057596
    Abstract: A device and a method for monitoring the operational state of rotor blades of a turbine from a position facing the blade tip of a passing rotor blade: A wavesource generates an electromagnetic wave and a wave guide directs the wave towards the blade tip. The waveguide is included in a resonator defining at least one discrete resonance frequency of the wave on the waveguide. An aperture at its front end emits an energy fraction of the wave toward the blade tip. The frequency of the wave is adjusted to the resonance frequency of the resonator at the momentary operation conditions, and a measuring unit compares at least one measurement parameter of the wave directed towards the blade tip with the corresponding measurement parameter of the wave reflected from the blade tip.
