EPRO MMS6120 Vibration Monitor – MMS 6000 Series Machinery Protection System
When a critical rotating machine — a turbine, compressor, or pump — begins to develop bearing faults, shaft misalignment, or rotor imbalance, the consequences of missing that signal are catastrophic: unplanned downtime, destroyed equipment, and in the worst cases, safety incidents that shut down entire production lines. The EPRO MMS6120 Vibration Monitor exists precisely to prevent that scenario. It continuously acquires, conditions, and evaluates vibration signals from proximity probes and velocity/acceleration transducers, triggering alarms and protective trips before mechanical damage becomes irreversible.
Within the MMS 6000 Series — EPRO’s flagship modular machinery protection platform — the MMS6120 occupies the role of the universal vibration measurement channel. It is engineered to meet the stringent requirements of API 670 (the industry standard for machinery protection systems) and is deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities worldwide. Its combination of measurement flexibility, relay output reliability, and seamless integration with the MMS 6000 rack architecture makes it one of the most specified vibration monitors in global industrial automation.
