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.
