55,998 ABSTRACT A system for monitoring the vibration of a plurality of shrouded turbine blades carried by a rotor and configured in a row includes a stationary sensor for inducing eddy currents in each shroud segment as each shroud segment passes the sensor. A target is located on each shroud segment for causing variations in the induced eddy currents. The sensor is responsive to the induced eddy currents to produce an output signal containing information corresponding to the time of arrival of the target at the sensor. Another sensor is provided for producing a pulse once per rotor revolution. A blade vibration monitor is responsive to the output signal and the once per rotor revolution pulse to extract blade vibration information therefrom.
