1 vb8 Product Datasheet Bently Nevada* Asset Condition Monitoring Description The vb8 instrument is a portable four-channel vibration data collector, analyzer and balancer. You can use this device for on-route and off-route data collection, machine-side analysis and diagnosis as well as on-site dynamic balance correction. The vb8 is certified for Class Division 2 hazardous areas. It is ergonomically designed and lightweight for all day comfort. The vb8 provides recordings with up to 2,800 lines of resolution and up to 80 khz Fmax. Our patented adaptive settling algorithm and 6Pack recording system offer quick, one-step data recording. The vb8 has plenty of storage and long battery life. This device is backed by five years of warranty. The vb8 is one of Bently Nevada hardware monitoring assets that work with System * and Ascent* Level 2 software. The vb8 offers the following features: Four channel simultaneous recordings Two-plane balancing with up to 4 sensors Support for acceleration, velocity, displacement, DC-coupled, current and voltage output sensors Triax-enabled 2,800 lines FFT resolution Supports 80 khz Fmax GB memory Spectrum and waveform recordings Demodulation for early detection of rotating machinery problems Page of 9
