EPRO MMS3120/022-000 9100-03047-01 Dual Channel Bearing Vibration Transmitter
1. Product Description
The 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.
