What is frequency spectrum analysis? How can it help solve engine vibration problems?
Engine vibrations are caused by a number of influences including fan imbalance, turbine imbalance, shaft misalignment, loose plumbing and ducting, and failing engine components (gearboxes, generators, fuel pumps, lube pumps, etc.). Frequency spectrum analysis is a feature of the PBS-4100 that helps to identify the sources of engine vibrations by isolating the various “components” of the vibration signal. Just as a prism breaks sun light into a rainbow revealing the different colors (or frequencies), the PBS-4100 uses its internal Digital Signal Processor to identify the different frequencies that are contained within an engine’s vibration signal. Because each of the sources of engine vibration has a characteristic frequency (or set of frequencies) that can used like fingerprints to determine the source of engine vibrations, by using Frequency spectrum analysis, the PBS-4100 can be used to quickly and accurately identify the cause or causes of the engine vibrations.
