Bently Nevada Machinery Condition Monitoring
Description
The vb5 Portable Data Collector instrument is a portable
single channel vibration data collector. It is ergonomically
designed and lightweight for all day comfort. You can use this
device for on-route as well as off-route data collection.
The vb5 Portable Data Collector provides recordings with up
to 6,400 lines of resolution and up to 40 kHz F
patented adaptive settling algorithm and 6Pack recording
system offer quick, one-step data recording.
The data collector has plenty of storage and long battery life,
and is backed by a five year warranty.
The vb5 Portable Data Collector is one of Bently Nevada
hardware monitoring assets that work with System 1
Evolution software.
