Bently Nevada Machinery Condition Monitoring

116M5255 Rev. JDescription
The vb7 Portable Data Collector, Analyzer and Balancer
instrument is a dual channel vibration data collector,analyzer and balancer. You can use this device for on-routeand off-route data collection, machine-side analysis anddiagnosis as well as on-site dynamic balance correction.
The vb7 Portable Data Collector, Analyzer and Balancer iscertified for Class 1 Division 2 hazardous areas. It isergonomically designed and lightweight for all day comfort.
The vb7 provides recordings with up to 6,400 lines ofresolution and up to 40 kHz Fmax. Our patented adaptive
settling algorithm and 6Pack recording system offer quick,
one-step data recording.
The vb7 Portable Data Collector, Analyzer and Balancer has
plenty of storage and long battery life, and is backed by a five
year warranty.
The vb7 Portable Data Collector, Analyzer and Balancer is oneof Bently Nevada hardware monitoring assets that work withSystem 1 software.
