FFT-Analyzer
The FFT-Analyzer Module allows you to
break down an overall vibration (mixture of
vibrations) into its individual harmonic compo-
nents. Different spectral lines are determined
with their own specific frequency and ampli-
tude. In relation to the overalls BCUp and
ECUp for the rolling-element bearing condi-
tion it is possible to calculate the envelope
spectra BCS and SED, in which the amplitu-
des at characteristic fault frequencies corres-
pond to the degree of damage of a
component or bearing.
In simple terms, the amplitude therefore
stands for the degree of damage and the fre-
quency for the damaged component.
Faults such as imbalance, transmission
damage, poor alignment or rolling-element
bearing damage can thus be diagnosed relia-
bly.
