Bently Nevada vb8 Portable Data Collector, Analyzer, and Balancer
The Bently Nevada vb8 is a four channel portable instrument that collects vibration data, analyzes it, and balances rotating machinery. It is the top model in the vb series (formerly Commtest) made by Bently Nevada part of Baker Hughes. Reliability and maintenance teams use it for on route and off route data collection, machine side diagnosis and on site dynamic balancing and it is certified for Class 1 Division 2 hazardous areas. It is also one of the portable assets that works with Bently Nevada System 1 software.
