​Do you need a high-end intrinsically safe vibration analyzer for the use in explosive environments? Then VIBXPERT EX is the right choice.

VIBXPERT EX is a high performance, intrinsically save, fully featured data collector, vibration analyzer and field balancer for easy condition monitoring and troubleshooting of rotating equipment in explosive environments such as petrochemical plants, refineries, offshore oil rigs, etc.

VIBXPERT EX collects field data including vibration information, bearing condition, inspection and process data and seamlessly integrates with the PRÜFTECHNIK universal OMNITREND software platform.

The modular firmware structure allows you to upgrade the VIBXPERT EX from a route data collector to a full-blown troubleshooting device with advanced features such as coast down/run-up measurements, event recording, ODS & modal analysis and cross-channel phase measurement.

It is also possible to connect the VIBXPERT EX to protection systems via the buffered outputs. This enables you to perform additional analysis such as shaft vibration, shaft centerline plots or orbits e.g. on turbines, compressors and other turbomachinery.

With the OMNITREND, the universal PRÜFTECHNIK Condition Monitoring software platform, measurements can be stored and analyzed, diagnosis reports can be generated and measurement tasks can be pre-configured and uploaded to the device for route based data collection. 

​As with all PRÜFTECHNIK's data collectors and vibration analyzers, you will benefit from free software and firmware updates, and low ownership cost
