Methods and apparatus are provided for measuring multiple operating parameters of a rotating shaft with a sensor. One embodiment of the apparatus comprises a sensor in close proximity to a matched pair of thumbnail depressions on the surface of a rotating shaft body. The thumbnail depressions enable the sensor to detect axial displacement and rotational speed of the shaft in addition to detecting radial displacement of the shaft body. Signal processing circuitry analyzes the sensor output data and computes separate values for the axial displacement, speed and radial displacement parameters. Additional filtering and signal processing techniques can be used to ascertain peak axial displacement, to reduce noise, and to compute other parameters, such as acceleration and power spectral density.
A system for measuring multiple operating parameters of a rotating shaft having an outer radial surface having at least one irregularity, the system comprising:
