Summary: | A method for non-contact measurement of multiple shaft parameters is provided. The method includes magnetically encoding multiple sections of the shaft using pulsed currents. The method also includes sensing a magnetic field of the encoded sections of the shaft using multiple sensors arranged circumferentially about the shaft. Further, the method includes generating a spectrum of periodical variations based on sensed magnetic field of the encoded sections of the shaft during rotation and determining multiple parameters based on recurrences of patterns of the spectra. |
