Even small system fluctuations can indicate dangerous system changes (e.g., loose parts, shaft rubbing, blocking of turbine vanes). These noises are difficult to detect in loud and complex environments like transportation systems, steam generators, turbines and drilling systems. Often, these small acoustic bursts are covered by the normal operational noise of the system and remain undetected.

Find acoustic damage patterns 1,000 times smaller than your operational background noise!
The new algorithm permits the detection of very small acoustic bursts even when covered by high background noise. AREVA NP’s LPMS detects changes in the system behaviour long time before traditional acoustic monitoring systems find any hint of the ongoing progress of development of wear or of malfunctions.

Your benefits

  • Extremely high detection sensitivity even in environments with noise levels up to 1,000 times higher than the event to be detected
