- Extraction of vibration components through a bandpass filter
Eliminating unnecessary noise components from vibration waveform.
- Elimination of noise components by a band elimination filter
Eiminating unique frequency components, such as inductive noise.
- Vibration detect mode
Vibration value mode, Envelope mode, Peak value mode,RMS (root mean square) value mode, Crest factor mode, Form factor mode.
- Measuring result is compared with upper/lower limit setting value, and judgment output is possible
HH, HI, OK, LO, LL
- Input waveform frequency diagnosis function by FFT
Frequency changes in a vibrational input waveform can be easily monitored by FFT spectrum. Equipment abnormality can be detected by monitoring the frequency changes that cannot be judged from the level shift of the vibrational input waveform.
