vbOnline Pro Condition Monitoring System

Datasheet

Bently Nevada Machinery Condition Monitoring

Description

The vbOnline Pro Condition Monitoring System uses
sophisticated signal processing algorithms together with
machinery operating states to monitor assets continuously.
This system is part of a condition based maintenance program
that identifies problems before assets begin to fail.

Benefits of the vbOnline Pro Condition Monitoring System are:

n Cost savings from reduced machinery down time
n Early detection of bearing defects
n Reduction of damage to assets

The monitoring system's key features are:

n Signal conditioning
n Alarming
n Speed inputs
n Control system communication

The vbOnline Pro Condition Monitoring System
communicates with System 1 via dual Ethernet connections.
The monitoring system uses 24 bit analog/digital conversion
and 40 kHz bandwidth to monitor rolling element bearing
machinery and gearing.

Sophisticated signal processing algorithms extract
measurement and health indices from each accelerometer
point. The algorithms can be custom tuned to specific bearing
and gear box characteristics.

The vbOnline Pro vbOnline ProCondition Monitoring System
exports trended measurements like direct, bias, speed, gap as
well as channel NOT OK status to third party systems such as
DCS via Modbus over ethernet.

The vbOnline Pro Condition Monitoring System components
are the vbOnline Pro monitor, System 1, Bently Nevada
Monitor Configuration software, transducers, and cables.
