Abstract
A method of estimating a clearance between at least one rotating object of a rotary machine and a second object is provided. The method includes measuring an operating parameter of the rotary machine. The method also includes obtaining signals corresponding to the at least one rotating object across multiple revolutions in time, wherein the number of the revolutions is determined based upon the measured operating parameter. The method further includes generating waveforms corresponding to the at least one rotating object from the obtained signals for the revolutions. The method also includes estimating the clearance between the second object and the at least one rotating object based upon the generated waveforms.
