Key Features

Dual-Channel Vibration Analysis
The VIBXPERT II can operate as a two-channel data collector and signal analyzer, allowing vibration signals to be measured and compared from multiple measurement points. PRUFTECHNIK’s current catalog identifies it as a dual-channel FFT data collector. (pruftechnik-dev.s3.us-west-1.amazonaws.com)

FFT Analysis
The VIBXPERT II provides advanced frequency-domain analysis for identifying common rotating-machinery problems such as:
Unbalance
Misalignment
Bearing defects
Gear damage
Looseness
Resonance
Other abnormal vibration conditions

Field Balancing
The instrument can perform one- and two-plane operational balancing. PRUFTECHNIK states that the balancing function uses an influence-coefficient method and provides several balancing approaches, including fixed-weight and fixed-location methods.

Route-Based Data Collection
The VIBXPERT II can be used for recurring machine-condition measurement routes, allowing maintenance teams to monitor vibration trends over time and identify developing machine problems.

Machinery Condition Monitoring
The VIBXPERT II is designed to provide maintenance technicians with vibration measurements that can help identify developing machinery faults before they lead to major failures.

Typical diagnostic targets include:
Unbalance – excessive vibration caused by uneven rotor mass distribution
Misalignment – vibration associated with incorrectly aligned shafts
Bearing damage – characteristic vibration patterns from damaged rolling elements or raceways
Gear defects – gear-mesh and tooth-related vibration
Mechanical looseness – vibration associated with loose components
Resonance – excessive response at natural frequencies

Field Balancing
The VIBXPERT II can be configured for operational balancing in one or two planes.

This makes it useful for balancing rotating components such as:
Fans
Pumps
Compressors
Turbine rotors
Generator rotors
Inductors
Other stationary rotating machines
