The VIBXPERT® vibration data col-lector and signal analyzercombines route-based data collec-tion with machine diagnostics inone tool.

VIBXPERT® excels in

• Fast data acquisition

• Complete data analysis on-site

• Useful knowledge-based setups– Intuitive for beginners– Powerful for experts

• Connections support almost allsensor types (e.g., triax sensors)

Powerful, yet intuitive

VIBCODE®

Automatic measurement loca-tion identification byVIBCODE® ’fingerprint’ – thecoded ring!• No mix up of measurement

locations• Reproducible measure-

ments• Stable connection• Defined contact pressure• Defined measurement di-

rection

Simultaneous!Carries out two measurementsat the same time – with orwithout trigger/RPM as re-quired.• Dual channel measure-

ments for diagnosis andcorrection- orbit- cross phase- coast down- 2-plane balancing

• Independently selectabledual channel measurementtasks.

Portable!Lightweight design with carry-ing strap, ideal for machinerysurvey.

The best connections!5 robust color-coded connec-tors on the upper side of thedevice are stable, cannot beconfused and are dustproof.

Condition monitoringRegular recording of measure-ment values provides a clearpicture of the machine condi-tion trend.

The 2-channel VIBXPERT®

comes equipped with phasemeasurement, coast downmeasurement, orbit, cepstrum.

Optional Expert Diagnostics fea-tures can be added at any time:• Extended Time Waveform

collection• Transient data collection• Modal/ODS capability• Data export via Universal File

Export (UFF).

OMNITREND® manages machinedata, programs measurement tasksand routes, and archives the resultsin a database (MS Access, Oracle*,MS SQL*). Comprehensive func-tions are available for evaluationand documentation: alarm check,trend preview, multiview, bandanalysis, waterfall display, fre-quency markers and variouscursors.

Alarms & diagnosisIf there is an alarm, narrowband monitoring in the fre-quency spectrum shows thedamaged component. Fre-quency markers supportidentification of characteristicfrequencies typical for specifictypes of damage. Additionalfunctions for diagnosis can becalled up via a menu.
