Product Introduction
The Bently Nevada Commtest VB8 is a portable, four-channel vibration data collector, analyzer, and balancer designed for field use in industrial machinery condition monitoring. This compact device allows technicians and engineers to perform on-route and off-route data collection, machine-side diagnostics, and on-site dynamic balance corrections.
The VB8 is engineered for ergonomic handling and all-day comfort, with a lightweight design suitable for extended use in the field. It is certified for Class 1 Division 2 hazardous areas, ensuring safe operation in environments with potentially flammable gases or vapors. The device interfaces seamlessly with System 1 software, enabling integration into Bently Nevada’s broader machinery monitoring ecosystem.
Equipped with a high-resolution recording system, the VB8 provides up to 12,800 lines of resolution and supports a maximum frequency (Fmax) of 80 kHz, capturing high-fidelity vibration signals across a broad spectrum. The device incorporates a patented adaptive settling algorithm and 6Pack recording system, allowing rapid, one-step data acquisition. Storage capacity is ample, and its battery provides extended operational time, backed by a five-year warranty, making it a reliable tool for long-term field operations.
