For some rotating assets and the processes associated with them, periodic route-based data collection is insufficient to trend changes when equipment is operating with a known defect. Portable online condition monitoring provides the RMS Acceleration, Velocity and Temperature with alarming to mobile phone. This allows NES to visualise the data necessary to stay on top of developing issues during normal operations and to respond quickly to sudden changes during transient conditions. Noble Engineering Services Pty Limited has developed a portable system known as BEARING GUARD™. This is a versatile, scalable system that can be deployed in a variety of configurations to deliver online condition monitoring exactly as needed for the application.
Every facility has assets and processes that fall into different reliability criticality categories, and most can be monitored using periodic manual data collection. For rotating assets, the most effective data collection is bearing and casing vibration readings with typical data collection once per month. But for some assets and the processes associated with them, this approach is insufficient to characterise the asset or the process health. Not knowing the moment-to-moment state of particular assets and processes could result in an unscheduled failure that brings the process to a halt, causing lost productivity.
Online monitoring provides frequent measurements 24/7 so you are “always aware” of asset health. Online monitoring is always in place and ready to collect data, especially during transitional states such as start-ups, during commissioning and coast-downs. Online measurements are collected from permanently installed sensors to provide more accurate, repeatable measurement with alarming texting to any nominated mobile device.
