THE COMPLETE VIBRATION ANALYSIS PACKAGE
The vb8™ analyzer is a uniquely sophisticated and feature-packed instrument that remains intuitive in operation and fl exible enough to suit every level of vibration analysis, from novice through to expert.
The Ascent® software included contains the collective experience of over 25 years of expert in-depth machine fault analysis.
1. Users with no prior experience or without a previously recorded vibration history can now establish a measurement program utilizing proven baseline values from ISO standards and The Proven Method from Technical Associates.* 2. Experienced users can now generate meaningful spectral alarm bands automatically rather than just relying on basic overall alarms or spectral 3. Veteran analysts can now objectively evaluate and compare their fi ndings against a time-tested and proven historical foundation.
Ascent Level 2 software
• Fully automated measurement parameter and alarm setups based on The Proven Method from Technical Associates*.
• ISO 2372 and 10816 standards Enhanced instrument functionality
• 4 channel simultaneous recordings • Triax. enabled • 12 800 line FFT resolution • 1 GB memory – Virtually unlimited spectra storage • Large, high resolution (HVGA) backlit LCD • Comfortable, ergonomic case design • Support for acceleration, velocity, displacement, DC-coupled, current, and voltage output sensors (both AC- and DC-coupled) • 2 plane balancing with up to 4 sensors - Simultaneous acquisition • Unique Commtest 6Pack™ recording system - Take up to 12 measurements simultaneously (HF, LF and Demodulation spectra and waveforms) across two channels • Numeric parameter input via keypad with trend and alarm capability in • Upgradable using the Profl ash system and free fi rmware updates for * The incorporation of The Proven Method is available exclusively in Ascent® software




EASY AND EFFICIENT TWO CHANNEL CAPABILITY
The vb7™ analyzer off ers the power and convenience of dual-channel measurement and dual-plane balancing. Its balancing functions enable quick diagnosis and correction of dynamic unbalance, the most common form of unbalance. The vb7 instrument's combination of accuracy, intuitive operation, ease of use, and outstanding storage capacity ensures the vb7 analyzer delivers a premium return on investment. The vb7 instrument includes the powerful Ascent® software in the purchase price.

• Route enabled - Build routes in Ascent and send these to your • CBDb - Commtest Bearing Database with over 30 000 bearings Enhanced instrument functionality
• 1 channel recordings • 6400 line FFT resolution • 1 GB memory – Virtually unlimited spectra storage • ≥ 95 dB dynamic range FOUR CHANNEL UNBALANCE
Lightweight and extremely portable, the vbBalancer+™ 4 channel and vbBalancer™ 2 channel instruments are easily carried onsite to any problematic machine. Their 10 hour battery life and 1 GB of internal memory ensure progress is uninterrupted, practically eliminating the need to pause in order to connect to a PC or power supply. The vbBalancer instruments also carry the legendary 5 year warranty and free lifetime Unbalance causes high levels of mechanical stress and vibration that are transferred directly to the bearings resulting in a proportional reduction in normal bearing life. With a few basic parameters, the vbBalancer instruments calculate acceptable unbalance levels to ensure machinery operates within international ISO 1940 guidelines.
vbBalancer instrument setup is minimal, quick, and easy. Only a few calibration runs are required, with or without removing your trial weight.
The vbBalancer instrument stores your previous balance run data. No need to waste valuable time performing calibration runs on repetitive or routine balance jobs.
Unbalance is computed quickly and the large backlit LCD display and user-friendly graphical interface indicate the angular position for weight The vbBalancer+ instrument enables full 4-sensor monitoring of both horizontal and vertical axes on each bearing. This ability provides confi dence that a balance on any one axis has not worsened vibrations on the other.
