vbOnline Pro

The vbOnline Pro provides automated, user-scheduled
monitoring of an asset’s mechanical health. It is a flexible andscalable system fully supported by the Bently Nevada System
1* asset health management and diagnostic software. The
system assists in the early detection of machinery andprocess problems. The vbOnline Pro provides economic
vibration monitoring for important assets. The device is easy
to install and configure.

Machinery applications

vbOnline Pro is an ideal condition monitoring instrument
for machinery with rolling element bearings and complex
gearboxes, including:• Agitators• Air Compressors• Blowers• Centrifuges• Cooling tower fans and pumps• Extruders• Machine tool spindles• Mill stands• Motors• Paper machines• Pumps• Small Centrifugal Compressors• Wind turbine generators

Hardware key features

System 1 enables strategic, data-driven maintenanceplanning and decision making to optimize asset reliability.
The key features and benefits include:• Compact and easy to install• Simultaneous 12 channel data sampling• Support for use with single PC or network• Wired Ethernet connection• 24-bit A/D conversion• Continues to operate and store data on communication loss
• Supports 2 wire IEPE/ICP accelerometers• Multiple user configurable waveforms and types per channel• Configurable setpoints with alarming and events• Machine operating state based data storage and alarming

Software key features

The vbOnline Pro and System 1 software complement yourpredictive maintenance program by performing costeffective data collection and condition monitoring analysis.
System 1 software is the core of Bently Nevada’s asset
health management solution. It is an innovative approachto provide users with a single ecosystem for full plant-widemachinery management.
