摘要：A method and apparatus for determining the operating condition of a turbineengine. An eddy current sensor is provided having a sensing field in communication with aplurality of rotating turbine blades during a revolution of a turbine engine. A threshold
point value is defined for the signature data. A plurality of positive threshold point pairsand negative threshold point pairs are identified. A plurality of positive threshold widthsfrom a plurality of times elapsed between the positive threshold point pairs and aplurality of negative threshold widths from a plurality of times elapsed between thenegative threshold point pairs are determined. A plurality of threshold ratios aredetermined from a plurality of pairs of positive and negative threshold widths. A varianceof the threshold ratios is correlated with an operating condition of the turbine engine.
