Abstract
Exemplary embodiments provide a surface of a rotating element with both a phase reference mark and a plurality of additional marks. A proximity probe detects the passage of both the phase reference mark and the plurality of additional marks as they rotate through a detection zone. Both a phase reference signal and a vibration reference signal are generated, which signals are used to calculate lateral and angular (and optionally torsional) vibration of the rotating elements.
