x_max_ACC_G - Peak or Highest RMS

Hardware
1

Hi

With vibration sensors, does x_max_ACC_G represent the Peak value of the vibration or simply the highest RMS value read over the reading time range? And x_velocity_mm_sec and x_rms_ACC_G ? Does these represent the instantaneous value read when the measurement was taken, or the average of the values read during the sampling interval?

Thanks :slight_smile:

Hi @bertrand.gauvreau
MAX (x_max_acc_G): This value represents the amplitude of the single largest frequency component (the highest peak) identified in the FFT spectrum. It is a “Peak-of-Peaks” measurement.
RMS (x_rms_acc_G): This represents the total energy of the entire vibration spectrum. It is calculated by taking all components of the signal into account.
x_velocity_mm_sec: The Velocity over the X axis in mm/sec
They are the calculated of the values read during the sampling interval.
