How Distributed Acoustic Sensing supports condition based maintenance strategies

September 2018 | Martin Rosenberger

This involves planning and controlling maintenance measures based on the actual condition of the equipment, systems and components (assets). Unexpected events due to faulty components and unnecessary work on fully intact elements can thus be reduced. This is possible thanks to the ever increasing amount of reliable data about the condition of the asset that is available in real time. Continuous acoustic condition monitoring of the infrastructure based on Distributed Acoustic Sensing (DAS) is a key building block of future solutions....
