Re: Problem with the amplitude of shaft frequency

Every thing seems good. It's a PCB PIEZOTRONICS accelerometer (Model 353B17 with frequency range from 1 to 10 kHz). It was used with an Oros OR25 Analyzer. The accelerometer and analyzer were verifyed using a shaker. We could read easily the the same amplitudes and the frequencies on the FFT analyzer and the shaker, which means to me that the setup is ok. The same setup was used to perform the tests on the rig,but as Said before the results didn't reflect the real shaft vibration.
