– POWERFUL MEASUREMENT SYSTEM Instant viewing of measurement data ProfiSignal provides you with comprehensive measurement software. In combination with the Vibro option, ProfiSignal can be adapted precisely to your vibration measurement needs. When configuring channels and before visualising and analysing measurement data with ProfiSignal, you can pre-process your signals according to your specific needs. A multitude of filter options are available for this purpose. A Bode plot enables you to instantly view the effects of your filter configuration. After configuration, you can visualise and...

Diagrams of option Vibro • Time signal diagram: Visualise and analyse measurement data for a time period. • Orbit diagram: View kinetic shaft paths including maximum deflection smax and the angular position / phase for constant-speed machine operation. • Shaft centerline diagram: View shaft centerline displacement as a function of speed during system start-up and shutdown. • Polar diagram: Displays vibration vectors including amplitude and phase informatio

Different portrayals of spectra In addition to a basic spectrum portrayal based on FFT analysis, you also get the following visualisation options: Envelope spectrum: Provides information on current machine condition at early stages of emerging damage and aids filtering of condition-relevant frequencies. Spectrogram: Portrays a spectrum‘s temporal progression. The colour display facilitates quantitative evaluation and enables simple tracking of changes in frequency or amplitude. Cascade spectrum: Enables the analysis of system behaviour during start-up and shutdown. Bode plot: Used to...

VIBRATION MONITORING AND As a plant operator, you want high levels of availability and efficiency. Operating conditions need to be optimised and downtimes prevented while service and maintenance intervals need to be performed according to machine status or maintenance schedule. Vibration monitoring and online analysis are therefore indispensable for your plant. Modern technology combined with a wide range of interfaces make this system not only applicable to new but also existing infrastructures.

ONLINE-ANALYSIS Rotating plant. Machines. Components. A practical example demonstrates how Expert Vibro devices are being used in hydroelectric power plants in dams, reservoirs and rivers. Vibrations on Kaplan and Francis turbines are being monitored using Expert Vibro devices that then transmit characteristic values via redundant PROFIBUS interfaces to control systems. With an Expert Vibro device, up to 16 vibration sensors can be synchronously measured, analysed and monitored. Static shaft positioning and dynamic shaft vibrations of journal-bearing shafts can be determined with reference...

SERVICE LIFE TEST STAND Securing competitiveness Service life testing is used to test products for long-term operation under realistic conditions and to certify service lives. It aids in the development of your products and thus directly contributes to securing your competitiveness. The special benefits you gain include simultaneous acquisition and monitoring of all relevant vibration and process data for the product under test, as well as highly dependable and available measurement data.

A practical example demonstrates how one of the world‘s leading manufacturers of ball, roller and journal bearings uses our systems for service life test stand. For numerous service life testing systems, Expert Vibro devices are being used in combination with Profi Message slaves and the ProfiSignal Klicks software as instrumentation and control technology. All vibration data is securely recorded together with process data such as temperatures, pressures, flow rates, speeds, etc. and monitored independently by the system. Various characteristic values and FFT spectra are portrayed online...

SPINDLE TEST STAND A spindle test stand is used to check spindle-driven machine tools in production for unacceptable levels of vibration and imbalance. This is vital in the production of components requiring a very high level of dimensional precision. Unacceptably high vibrations and imbalances in spindle systems also mean significantly higher loads on bearings and thus lead to higher levels of wear and machine downtimes. A spindle test stand therefore helps to ensure high standards of quality for manufactured goods and increases levels of machine availability.
