Bearing Vibration Monitoring Solution – EPRO MMS6120 | MMS Series
Where This Product Is Used
The EPRO MMS6120 is a dual-channel bearing vibration monitor engineered for continuous machinery protection in high-stakes industrial environments. It is routinely specified in:
- Oil & Gas: Compressor trains, gas turbines, and pipeline pumping stations where unplanned downtime carries six-figure hourly costs.
- Power Generation: Steam turbine bearing housings and generator end-shields requiring 24/7 vibration surveillance.
- Petrochemical & Refining: Reactor feed pumps, centrifugal compressors, and agitator drives subject to API 670 compliance mandates.
- Marine & Offshore: Propulsion shaft bearings and auxiliary machinery on FPSO vessels and offshore platforms.
- Heavy Industry: Rolling mills, large fans, and kiln drives where bearing failure propagates to catastrophic structural damage.

Why Engineers Specify This Model
- Dual-channel architecture monitors two bearing positions simultaneously from a single module slot, reducing rack space and wiring cost.
- API 670 alignment satisfies machinery protection requirements for critical rotating equipment without additional engineering waivers.
- Independent alarm setpoints per channel allow Alert and Danger thresholds to be tuned to each machine’s baseline vibration signature.
- 4–20 mA analog output integrates directly into DCS/SCADA historians (Honeywell, Emerson, Yokogawa, Siemens) without signal conditioning.
- MMS modular platform enables hot-swap maintenance and mixed-monitor rack configurations alongside MMS6110, MMS6210, and MMS6820 modules.
- Proven EPRO pedigree — EPRO monitors are installed on over 100,000 machines globally and are accepted by major EPC contractors and insurance underwriters.
Complete System Bill of Materials
A typical MMS6120-based bearing protection loop requires the following components:
- MMS6120 – Dual-Channel Bearing Vibration Monitor (this module)
- MMS6000 / MMS6005 – MMS Rack & Power Supply
- Seismic velocity sensor or accelerometer (e.g., EPRO PR9268 series)
- Extension cable with MIL-spec connector
- Relay output terminal board (if hard-wired trip required)
- DCS analog input card (4–20 mA, 16-bit resolution recommended)

Application-Specific FAQ
Q: Can the MMS6120 replace a Bently Nevada 3300/16 in an existing rack?
A: No — the MMS6120 uses the EPRO MMS backplane, which is not pin-compatible with Bently Nevada 3300 racks. A rack adapter or full rack replacement is required.
Q: What transducer types are compatible?
A: The MMS6120 accepts seismic velocity sensors (e.g., PR9268) and can be configured for accelerometer inputs depending on firmware version. Confirm transducer impedance and sensitivity with our technical team before ordering.
Q: Is the MMS6120 suitable for use in hazardous areas (ATEX / IECEx)?
A: The monitor module itself is installed in a safe area control room. Zener barriers or galvanic isolators are required for transducers located in Zone 1/2 hazardous areas.
Q: What is the typical lead time?
A: In-stock units ship within 3–5 business days. For sourced units, lead time is 2–4 weeks. Contact us for current stock status.
Q: Do you provide calibration certificates?
A: Calibration certificates are available for reconditioned units. New surplus units ship with OEM documentation where available.
