Abstract
Turbine blade vibration detection apparatus having two or more extremely narrow beam radar sensors positioned to direct their radar signals towards predetermined blade row or rows. A blade identification circuit is provided for each blade row having an associated radar sensor for providing an output count indicative of which blade is being examined by a particular radar sensor. The gating of the blade count and radar sensor signals is governed by a computer which performs a frequency analysis of the radar signals and compares the result with predetermined threshold values.
