Overview
Cross Channel Phase collects spectra to determine the phase shift and coherence relationships between two sensor locations. Coherence compares two sensor signals and determines if the vibration is related and confirms the quality of the data. A value near 1.0 indicates there is some cross vibration from other equipment.
Cross Channel Phase can monitor a single frequency or acquire full spectral plots.
Note: Cross Channel Phase is not available on the
single-channel analyzer.
Issue | Sensor location |
---|---|
Misalignment | Measure across a coupling. |
Looseness/weakness | Measure across mechanical interface. |
Coherence | One sensor on each machine. |
