Patent attributes
An assembly for rotational equipment includes a rotor, at least one sensor, and a controller. The rotor includes a first plurality of teeth arranged on the rotor in a first circumferential array of teeth at a first axial position. The at least one sensor includes a first sensor positioned radially adjacent the first circumferential array of teeth at the first axial position. The at least one sensor is configured to generate an output signal waveform. The controller is in signal communication with the at least one sensor. The controller includes a processor and non-transitory memory in signal communication with the processor. The non-transitory memory stores instructions which, when executed by the processor, cause the processor to measure a dynamic whirl displacement of the rotor at the first axial position using the output signal waveform.
