4.2.4 Bandpass filter for rolling-element bearing condition
The bandpass filter for the assessment of rolling-element
bearing condition consists of a highpass filter and a lowpass
filter each with a respectively fixed corner frequency.
4.2.5 Lowpass filter for rolling-element bearing condition
♦ <Corner frequency > of the filter:
The corner frequency of the lowpass filter for rolling-element bearing
condition is fixed at 10 kHz. The sensible use of this filter is limited to
the use of acceleration sensors.
4.2.6 Highpass filter for rolling-element bearing condition
♦ <Corner frequency > of the filter:
The corner frequency of the highpass filter for rolling-element bearing
condition is fixed at 1 kHz. The sensible use of this filter is limited to the
use of acceleration sensors.
4.2.7 Variable bandpass filter
The variable bandpass filter consists of a variable highpass
filter and a variable lowpass filter with a respectively
adjustable corner frequency.
4.2.8 Variable lowpass filter
♦ <Corner frequency > of the filter:
The corner frequency of the variable lowpass filter is as a rule preset to
1 kHz. The setting in the instrument can be changed according to the
values shown in table 1.
Filter settings that are sensible for the machine being monitored are the
responsibility of the user.
