Abstract
A method of monitoring a clearance distance between a rotatable member and a stationary member within a rotary machine is provided. The method includes exciting a probe with a first modulation signal when the rotatable member is rotating at less than or equal to a predetermined rate, exciting the probe with a second modulation signal when the rotatable member is rotating at greater than the predetermined rate, measuring the clearance distance between the rotatable member and the stationary member using the probe excited with at least one of the first modulation signal and the second modulation signal.
