  • Waveform acquisition optimization
    Patent number: 11898994
    Abstract: A computer-implemented process determines, based on bearing fault frequencies, optimum values for the maximum frequency (Fmax) and the number of lines of resolution (Nlines) to be used in collecting machine vibration data so as to adequately distinguish between spectral peaks for identifying faults in machine bearings. The process can be extended to any other types of fault frequencies that a machine may exhibit, such as motor fault frequencies, pump/fan fault frequencies, and gear mesh fault frequencies. Embodiments of the process also ensure that the time needed to acquire the waveform is optimized. This is particularly useful when collecting data using portable vibration monitoring devices.
    Type: Grant

    Date of Patent: February 13, 2024
