Abstract
Methods and apparatuses are described for determining the operating status of a turbine engine. An eddy current sensor is provided having a sensing field in communication with a plurality of rotating turbine blades during a revolution of a turbine engine. The sensor generates signature data for the passage of each blade. An analytic waveform is determined from the signature data and blade characteristic data is determined from the analytic waveform.
