Description
EPRO MMS3120/022-000 9100-03047-01 Dual Channel Bearing Vibration Transmitter
1. Product DescriptionThe
EPRO MMS3120/022-000 9100-03047-01 is a high-performance dual-channel bearing vibration transmitter designed for real-time monitoring of rotating machinery. As part of Emerson EPro’s MMS 3000 system, it processes signals from seismic or eddy current sensors (e.g., PR6422/…, PR6423/…, PR6424/…) to measure absolute vibration velocity or displacement. With configurable outputs and compliance with API 670 and VDI 2056 standards, it ensures reliable protection and predictive maintenance for critical equipment in industries like power generation, oil/gas, and manufacturing.

3. Advantages and Features
- Dual-Channel Design: Simultaneously monitors two vibration axes for comprehensive machinery health assessment.
- Multi-Sensor Compatibility: Supports PR6422 to PR6425 sensors with configurable ranges (e.g., 0–250μm for PR6422).
- Real-Time Fault Detection: Continuously checks sensor integrity, cable connections, and system voltages, triggering alarms via function outputs.
- Flexible Configuration: Field-adjustable measurement settings, alarm thresholds, and output options via MMS3910W software.
- Explosion-Proof Option: Available models for hazardous environments (e.g., IP67-rated variants).
4. Application Areas and Case Studies
Industries:
- Power generation (turbines, generators)
- Petrochemical and oil/gas (compressors, pumps)
- Manufacturing (rotating equipment)
Case Study:
A major petrochemical plant reduced unplanned downtime by 25% using MMS3120/022-000 to monitor bearing vibrations in centrifugal pumps. Early detection of misalignment and imbalance via real-time velocity measurements enabled proactive maintenance, preventing costly failures.
5. Competitor Comparison
Compared to single-channel solutions, the MMS3120/022-000 offers:
- Redundancy: Dual-channel monitoring for higher reliability.
- Simplified Integration: Built-in RS485/Profibus DP options reduce cabling complexity.
- Faster Response: <10ms processing time for dynamic vibration analysis.

6. Selection Recommendations
- Sensor Type: Choose seismic sensors for absolute vibration or eddy current sensors for relative displacement.
- Environment: Opt for IP67-rated models in wet/dusty conditions.
- Communication: Select RS485/Profibus DP for large-scale systems requiring remote monitoring.
7. Precautions
- Installation: Mount vertically to avoid condensation and ensure proper sensor alignment.
- Calibration: Perform annual checks using EPro-certified tools to maintain accuracy.
- Safety: Use surge protection devices in high-EMI environments to prevent signal interference.
