A manufacturing facility was experiencing recurring machine shutdowns caused by clogged oil filters. Each production line utilized two filters — a primary and an auxiliary — located in the basement. Operators had no real-time visibility into filter condition and were often unaware when a filter became restricted.

As filters clogged, oil flow decreased and machines would eventually starve for lubrication, leading to unplanned downtime until operators manually switched to the backup filter.

Implementation

Vibration sensors were mounted to the pipes feeding each oil filter. As filters began to clog, pipe vibration increased — providing a measurable early indicator of restriction.

After several days of baseline data collection, warning and critical alarm thresholds were established. When vibration exceeded these limits, operators received immediate visual and audible alerts at their designated stations.

This allowed operators to switch to the auxiliary filter proactively and service the clogged unit before oil starvation could occur.

Results & Operational Impact

Beyond eliminating shutdowns, the system delivered actionable trending data. Maintenance teams gained visibility into how frequently filters were clogging and which lines required more frequent attention.

Lessons Learned

This case highlights the importance of monitoring secondary systems — such as lubrication infrastructure — that may not appear critical but can significantly impact production when compromised.

By combining real-time monitoring with clear operator alerts, facilities can shift from reactive troubleshooting to proactive intervention, improving both uptime and maintenance efficiency.

Conclusion

Wireless condition-based monitoring transformed a recurring operational disruption into a controlled, predictable maintenance task.

By detecting early vibration changes associated with clogged filters, the facility eliminated downtime, improved reliability, and gained long-term insight into lubrication system performance.
