If you're looking for a predictive maintenance sensor that continuously monitors acoustic emissions from machinery, I'd focus on industrial acoustic emission (AE) monitoring systems rather than ordinary sound-level meters. These systems detect high-frequency signals associated with friction, material damage, wear, leaks, and other developing faults.
There are three main approaches worth considering:
- True acoustic emission sensors: Detect high-frequency elastic waves transmitted through a machine's structure. Best suited to detecting subtle mechanical activity and degradation.
- Ultrasonic acoustic sensors: Monitor high-frequency sound for early warning of bearing problems, lubrication issues, cavitation, and leaks.
- Multimodal predictive maintenance sensors: Combine acoustic measurements with vibration and temperature, often adding automated anomaly detection and alerts.
The right choice depends on whether you need continuous unattended monitoring, detailed fault diagnosis, or a relatively simple sensor that feeds data into your own predictive maintenance software.
