Bently Nevada Machinery Condition Monitoring

111M7155 Rev. HDescription
The vb6 Portable Vibration Data Collector instrument is aportable four channel, high resolution vibration datacollector. 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 vb6 Portable Vibration Data Collector samples all fourchannels simultaneously to provide recordings with up to
12,800 lines of resolution and up to 40 kHz Fmax. Our 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 vb6 Portable Vibration Data Collector is one of Bently
Nevada hardware monitoring assets that work with System 1software.
