Core Function for Predictive Maintenance
The EPRO MMS6120 is a Dual Channel Bearing Vibration Monitor designed for continuous machinery health assessment. This unit simultaneously monitors two independent electrodynamic vibration velocity sensors. It provides critical data for predictive maintenance programs by detecting early signs of bearing wear and imbalance. Consequently, it helps prevent costly unplanned downtime and catastrophic machine failures.
Key Features and Signal Integrity
This monitor operates in a “Danger” mode, triggering alerts when vibration exceeds pre-set danger thresholds. It features galvanic isolation between sensor inputs and the power supply for superior noise immunity. The MMS6120 offers a high input resistance greater than 100 kΩ to minimize signal loading and distortion. Furthermore, its measuring ranges are continuously adjustable via configuration software for application-specific tuning.
Detailed Technical Specifications
Engineered for industrial environments, the monitor functions reliably across a wide temperature range. It supports a frequency measurement range from 10 Hz to 1000 Hz, per VDI 2056 standards. The following table details its comprehensive electrical, measurement, and physical parameters.
