Bently Nevada Machinery Condition Monitoring
Description
Unbalanced rotating machinery can cause high levels of
vibration which can degrade bearing life and cause major
mechanical complications. Reduce the possibility of outages
and downtime with our vbBalancer and vbBalancer+
portable instruments. Used on-site, they detect unbalanced
machinery and help you diagnose and immediately fix issues
before they become serious, expensiveproblems.
After you input a few basic parameters describing a machine,
use vbBalancer to identify current unbalance levels and
determine ifthe machine is operating within ISO 1940
standards.
If a machine needs balancing, use vbBalancer to identify the
mass and position of permanent balance weights.
To verify that balancing is working, the vbBalancer Series
record basic vibration spectra. Use vbBalancer to view
spectra before and after balancing to validate broad-band
improvement.
132M3167 Rev. A
The two-channel vbBalancer instrument has two
accelerometer inputs for simultaneous recordings. The fourchannel vbBalancer+ instrument uses vibration readings
from four accelerometer inputs to calculate the optimum
balance weights to apply to two correction planes,
minimizing total machine vibration. This enables you, for
example, to monitor both horizontal and vertical axes on a
two-bearing machine, giving you confidence that the
balance you applied to one axis has not worsened vibration
on the other.
The vbBalancer Series provides recordings with up to 800 lines
of resolution and up to 5 kHz Fmax. The vbBalancer Series has
plenty of storage capacity and features all-day battery life.
We back these instruments with a five year warranty.
