Expert Vibro

Manufacturer: Delphin show products

With its Expert Vibro device, Delphin have successfully combined the processing of complex functions with high levels of flexibility in a user-friendly system. Vibration measurement systems can now be used where they had previously been economically infeasible. The device is equipped with a high powered, dual core FPGA processor based on ARM technology giving users ample reserves of processing power.


Vibration measurement – Compact, intelligent and fast
Expert Vibro combines the requirements and functioning of modern vibration measurement systems into a highly compact device. Other systems usually require multiple equipment. Vibration measurement is made easy with Expert Vibro. System installation and familiarization are short so that users can quickly start processing their data.

ProfiSignal - Vibration monitoring and analysis
Expert Vibro is fully compatible with the ProfiSignal software and is available with the "Vibro" option. ProfiSignal is a complete software package for use in data acquisition analysis, visualization and automation.
The software is very user-friendly with specialist functions that are simple to operate. ProfiSignal is modular, scalable and available in the three versions: Go, Basic and Klicks.

  • ProfiSignal Go: Software for measurement data acquisition
  • ProfiSignal Basic: Software for process visualization and monitoring
  • ProfiSignal Klicks: Software for process automation and measurement procedures

The ProfiSignal Vibro option extends ProfiSignal with the following diagrams:

  • Spectrum (FFT)
  • Cascade diagram
  • Time signal (y(t), y(x))
  • Orbit

and enables portrayal of the vibration data acquired and processed by Expert Vibro. Orbit and trend graphs portray kinetic shaft orbits including maximum Smax deflection and angular position / phase.

Expert Vibro configuration is performed using Delphin's DataService/Configurator software. The configuration procedure is based on Delphin's tried and tested, intuitive system. Both online and offline configuration is possible. The configuration data is securely stored within the Expert Vibro device.
