Caractéristiques du produit

Versatile Module for individual Vibration Analysis

In the expert module, the frequency bands to be monitored can be freely defined, both statically as well as dynamically depending on other measurands. The following parameters are determined for each frequency band as a result of the analysis: Peak, RMS (square average), Peak frequency.

Order Analysis and Envelope Calculation

In the calculation profile of the ibaInSpectra Expert module, the user can select a speed signal for re-sampling the input signal depending on the rotation speed. This speed signal can be a pulse train, a pulse counter or an absolute speed value.

Alert and Alarm

When configuring the alert and alarm limit values, the ibaIn- Spectra Expert module automatically supplies analog or digital signals which are activated as soon as the limit values are exceeded. Via the output interfaces of ibaPDA, these signals can be made available to other systems for alerting or interventions in the process control.

ibaInSpectra Auto-Adapting Module

Automatically learn Spectral Analysis

The auto-adapting module can be used to detect damage to machines, gearboxes and motors as well as qualityrelated changes in process vibrations already at a very early stage. The self-learning InSpectra module offers optimal protection for systems through automatic monitoring in real time using learned reference values.

Auto-Adapting Module at a Glance



  • Self-learning InSpectra module for spectral analysis
  • Reference spectra for various process conditions
  • Analysis across the entire spectrum
  • Automatic learning of reference values
  • Individual definition of warning and alarm limits
  • Online visualization in real time
  • Early detection of changes and damage

Caractéristiques du produit

Detecting Damage at an early Stage

The auto-adapting module is able to use a series of spectra to learn what the ideal spectrum should look like. The so-called reference spectrum can be learned for various process states, which, for example, relate to different speeds, materials or load areas, etc.

Learning and Monitoring

Instead of having to manually configure a frequency analysis for certain ranges, all ranges of the spectrum are considered in the auto-adapting module. In the process, the spectrum can be individually divided into any number of ranges.

Convincing characteristic Values

The auto-adapting module calculates meaningful characteristic values for every state.

ibaInSpectra Orbit Module

Monitoring the Shaft Motion

The ibaInSpectra Orbit module can be used to monitor the shaft motion relative to bearing housing and therefore allows a reliable monitoring and evaluation of the machine condition. For a stable calculation of the parameters, even at different speeds, the input signals are sampled relative to speed.

Orbit Module at a Glance



  • Calculation of characteristic values for validation and monitoring
  • Display of one or several shaft motions (orbit)
  • Display of the shaft center motion (centerline)
  • Speed-dependent resampling
  • Visualization of acceleration levels
  • Calculation profiles for multiple usage
  • Customized visualization
  • Display of the phase reference
  • Averaging over several rotations (linear or peak hold)

Caractéristiques du produit

Calculation of speed-dependent characteristic Values

This ensures not only reliable results for all conditions but also allows an averaging of the orbit over several revolutions.

Better Insight thanks to a flexible Visualization

The orbit view offers various possibilities to adjust the visualization of the shaft motion individually. So the shaft motion can be visualized including phase reference. In addition, the movement history of the shaft center can be displayed over a time period.

Offline detailed Analysis with Playback Function

For a detailed offline analysis the recorded data can be opened together with the calculation profiles in ibaAnalyzer-InSpectra. Shaft motions can be analyzed subsequently and can be compared with other process data to recognize correlations. Additionally, the behavior can be reproduced at certain points of time, using the playback function.
