In recent years, some issues of the condition monitoring of rotating machinery have been tackled with the Instantaneous Angular Speed (IAS) analysis. In fact, from the variation of the IAS during the machine loads\u2019 cycle it\u2019s possible to identify defects and faults. The current work focuses on the estimation of the IAS through the Elapsed Time (ET) method and compares the results with the measurements of a B&K torsional laser vibrometer type 2523, allowing to highlight the differences between the methods and the influences of the processing parameters. The ET is based on the measurement, with a counter, of the time elapsed between the pulses of an encoder. Obviously, both encoder\u2019s and counter\u2019s characteristics, (the num...
