AIM Spectrum Analysis Developments

There are exciting new developments afoot at Asset Handling with additional solutions being developed for Asset Insight Manager, we are now upgrading the existing AH21 sensors to incorporate an environmental monitoring solution including continuous remote Vibration analysis to enable customers to improve rotary equipment reliability and monitor its trend over time.Â

Our units record vibration using high frequency accelerometers attached to the asset on multiple mounting points to detect multiple failure scenarios and optimum orientation.  The data is recorded and sent to our cloud based system for analysis of critical bands within the spectrum for the type of asset being monitored to detect potential operating issues.Â

Vibration analysis can detect a wide variety of issues with

  • Gearing
  • Alignment
  • Electrical
  • Bearings
  • Balance
  • Looseness (between stationary and moving parts)
  • Over tension

High resolution velocity spectrums at a 2 second duration @ 0.5Hz resolution  are available for viewing online allowing engineers to compare results over time or to assess the impact of maintenance regimes leading to a more cost effective and proactive intervention practice.

Machine learning is being applied to the spectral data to identify patterns and any changes to those patterns so that engineers can be notified to perform a more detailed analysis. Spectral data coupled with maintenance records and failure modes allows the algorithm to more accurately predict the cause of failure at component level and aid root cause analysis.

Our unit is designed to improve the reliability of your assets and reduce the risk of failure critical assets

  • Online continuous vibration analysis
  • Machine learning to detect anomalies or remote access for engineering review
  • Reduced unnecessary & costly interventions
  • Gain access offsite expertise
  • Reduce Expensive downtimes
  • Easily identify assets requiring closer inspection/intervention across portfolio
  • Optimisation of invasive maintenance activities through real-time monitoring

Our units are IP69 rated as standard allowing the units to be fitted in harsh environments, we also offer an ATEX EXD rated unit for the ZONE 0 application in the petrochemical and pharmaceutical industries.

The benefits of the upgraded AH21 units with spectral analysis are that in addition to monitoring data which alerts to any potential issues, the machine learning element takes into account any behaviour that is normal for that particular asset but which may previously have flagged as an issue. Environmental factors such as where the asset is situated are also taken into account.
