The work considers the applicability of signals coming from rotor-mounted sensors in machine diagnostics. In the experiments, such sensors were implemented by piezoelectric patches bonded to the surface of a shaft. The laboratory stand also included more common sensors: laser sensors that measured the displacement of the central disc, as well as accelerometers mounted on the supports. The signals measured are analysed using the so-called full FFT method and the spectra are compared. The results show that the signals from piezoelectric sensors can be processed so that their spectral content is similar to typical spectra obtained using stator-mounted sensors.
