EPRO MMS6120

Advantages and Characteristics

1. Dual-Channel Redundancy: Simultaneously monitors two bearings, providing comprehensive health insights.
2. Non-Contact Eddy Current Technology: Enables precise measurements in harsh environments (e.g., high temperatures, corrosive gases).
3. Real-Time Analysis: Processes data at up to 10 kHz, detecting anomalies like resonant frequencies or lubrication issues.
4. Predictive Maintenance: Configurable alarms and historical trend analysis reduce unplanned downtime.
5. Self-Diagnostic Features: Monitors sensor integrity and circuit health, ensuring reliable operation.

Application Fields and Case Studies

• Power Generation: Turbine and generator bearing monitoring to prevent catastrophic failures.
• Oil and Gas: Compressors and pumps in offshore platforms.
• Manufacturing: Heavy machinery in automotive and steel plants.

Case Study: A steel mill reduced maintenance costs by 15% using the EPRO MMS6120 to detect bearing misalignment in a rolling mill, enabling timely repairs before component failure.
