Overall Velocity
The Overall Velocity measurement provides a summation of the low-frequency vibration
energy, which indicates fault conditions such as imbalance, misalignment, looseness, and
late-stage bearing problems.
The AMS Wireless Vibration Monitor uses (lower-frequency) Overall Velocity in
conjunction with (higher-frequency) PeakVue to provide a holistic solution across all
frequencies while optimizing the usage of the limited power and bandwidth available in a
wireless device. The majority of developing fault conditions manifest in one or both of
these key parameters.
The difference between the standard vibration waveform and the associated PeakVue
waveform is shown in
. Overall Vibration indicates energy from
shaft rotation, expressed in units of RMS velocity per the ISO 10816 standard. PeakVue, on
the other hand, filters out the rotational energy to focus on impacting. Impacting is
expressed in units of Peak acceleration. This indicates key mechanical problems such as
rolling element bearing faults, gear defects, and under-lubrication.
