Remote Condition Monitoring Diagnostics for Steel Production

By Published on June 7, 2022


Brüel & Kjær Vibros innovative flight recorder, built in VC-8000/SETPOINT system, is a great tool to have as part of a remote condition monitoring system. The flight recorder was recently used at an air separation plant in Germany. This plant provides air separation for steel production.

The machine monitored at the plant is an 8MW, 6-stage integrally geared centrifugal compressor manufactured in 2000. The plant recently replaced its old machine protection system with the VC-8000/SETPOINT system. While the plant was changing its system they needed to monitor the machine in the meantime. It was during this time the flight recorder shined.

During machine startup, the system detected a fault. The fault revealed high vibrations as well as pressure loss. Not having the monitoring system connected to a network nor having experts on hand to analyze the data, they sent the data to B&K Vibro to have a machine diagnostic engineer investigate. This data was easily transferred by removing the SD card from the VC-8000/SETPOINT system and putting it on a cloud-based file-sharing site. Without this capability, the customer would have needed to send the unit back to the OEM. Doing so would have resulted in more than €2 million in outage costs. The flight recorder proves itself effective for remote condition monitoring diagnostics.

Read the application note, “Compressor rubbing and looseness diagnosed from protection system flight recorder” for all of the details.
