In industrial, vibration is used as a healthy indicator of the machine, mostly in rotating equipment. Mechanical vibration has become a major axis to monitor the machine condition that measured by vibration transducer and processed by vibration analyzer with FFT Spectrum or Time Waveform as its result.
For having a line on this discussion, vibration analysis is the single solution to express the main problem of the machine. The purpose of vibration analysis is to identify the defects, machine faults, and root cause in order to predictive maintenance program.
