Frequency-Amplitude Correlation Chart

This scatterplot displays the correlation between Dominant Frequencies and the PPV (Peak Particle Velocity) of the recordings.

When the data spans a period longer than three days, aggregation is applied. In this case, the alarm threshold is hidden because the displayed data does not represent all sensor readings, including alarm events. To view all detected events, the time interval must be limited to three days or less.

When the displayed data falls within a period shorter than three days, the data is not aggregated, the set alarm threshold becomes visible, and events exceeding the threshold are highlighted in red.

PPV - Peak Particle Velocity

This chart shows the trend of the three-dimensional velocity calculated using the PPV on the three axes. The PPV represents the maximum of the velocity vector magnitude recorded during the considered time interval, calculated simultaneously for the three components (x, y, z).

FFT Dominant Frequencies

This chart displays the dominant frequencies on three axes, corresponding to the peaks of the maximum amplitude spectrum.

FFT Amplitude

This chart represents the trend of the maximum FFT amplitude across three axes. The peak amplitude of the spectrum represents the maximum value of the FFT for each velocity vector component, calculated by windowing the velocity’s time evolution around the highest peak observed within the monitoring period.
