THE COMPLETE VIBRATION ANALYSIS PACKAGE
The vb8™ analyzer is a uniquely sophisticated and feature-packed instrument, yet it remains intuitive in operation and exible enough to suit every level of vibration analyst, from novice through to expert.
The included Ascent® software contains the collective experience of over 25 years of expert in-depth machine fault analysis.
1. Users with no prior experience or without 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 band guesswork.
3. Veteran analysts can now objectively evaluate and compare their 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
* The incorporation of The Proven Method is
available exclusively in Ascent® software

FOUR CHANNEL UNBALANCE CORRECTION PACKAGE
Lightweight and extremely portable, the vbBalancer+™ 4 channel and vbBalancer™ 2
channel instruments are easily carried on site 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 Commtest’s
legendary 5 year warranty and free lifetime support as standard.
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.
Setup vbBalancer instrument setup is minimal, quick and
easy. Only a few calibration runs are required, with or without removing your trial weight.
Memory
The vbBalancer instrument stores your previous balance run data. No need to waste valuable time performing calibration runs on repetitive or routine balance jobs.
Balance
Unbalance is computed quickly and the large backlit LCD display and user-friendly graphical interface indicate the angular position for weight correction.
The vbBalancer+ instrument allows full 4-sensor monitoring of both horizontal and vertical axes on each bearing. This ability provides condence that a balance on any one axis has not worsened vibrations on the other.
