Abstract: A seal includes a carbon seal that is disposed about an axis and extends between a first axial end and a second axial end. The second axial end includes a seal surface and a radially outer edge of the seal surface is axially spaced from a radially inner edge of the seal surface along the axis.

Abstract: A method of monitoring a rotating component includes gathering an electrical signal from a sensor arranged adjacent a rotating component of an assembly. The electrical signal is transformed from a time domain into a frequency domain. The electrical signal is compared to an expected signal.
