Product Overview
The EPRO MMS6110 is a high-precision dual-channel shaft vibration monitoring module manufactured by EPRO (Germany), designed for critical rotating machinery protection in industrial automation systems. As part of EPRO’s MMS 6000 series, this module specializes in measuring radial relative shaft vibration using eddy current sensors (e.g., PR642x series with CON0x1). It serves as a core component in turbine control systems, providing real-time data acquisition for parameters like vibration amplitude, phase, and gap voltage to safeguard equipment such as steam turbines, gas turbines, compressors, and fans. The MMS6110 integrates signal conditioning, alarm management, and diagnostic capabilities, enabling seamless communication with broader systems like DCS, SCADA, or plant networks via RS-232/485 ports or Ethernet interfaces .
Engineered for resilience, the EPRO MMS6110 supports hot-swappable operation and redundant power inputs, ensuring uninterrupted performance in harsh environments with operating temperatures ranging from -20°C to +70°C. Its dual-channel architecture allows independent or combined operation per international standards (API 670, VDI 2059), while features like built-in linearization, sensor self-diagnostics, and password-protected configuration enhance reliability. By processing dynamic and static signal data from eddy current sensors, the module detects imbalances, misalignment, or bearing wear, facilitating predictive maintenance and reducing downtime in power generation, oil and gas, and manufacturing sectors .

Key Features and Advantages
Dual-Channel Precision Monitoring: The EPRO MMS6110 provides simultaneous, isolated measurement of shaft vibration across two channels, each configurable for peak-to-peak (Spp) or zero-peak (Sop) values. This enables comprehensive assessment of radial vibration patterns, with dynamic outputs (AC1/AC2) supporting frequency analysis for early fault detection. The module’s built-in linearization processor ensures accurate signal conversion, compatible with industry-standard eddy current sensors like the PR642x series .
Advanced Diagnostics and Safety: Integrated self-test functions continuously monitor sensor health (e.g., short-circuit/break detection) and module integrity. Password-protected configuration prevents unauthorized changes, while alarm hysteresis and a “limit multiplier” (1.00–5.00×) suppress false triggers during transient conditions like critical speed passage. The module’s “channel OK” outputs and LED indicators (green/red) provide instant status visibility, reducing maintenance effort .
Seamless Integration and Flexibility: With support for MODBUS RTU, CANopen, and analog outputs, the MMS6110 connects effortlessly to control networks (e.g., Ethernet, WAN/LAN). Its hot-swappable design allows maintenance without system shutdown, and compatibility with TMR (Triple Modular Redundancy) configurations ensures fault tolerance in critical applications. The module also records start/stop data for trend analysis, aiding predictive maintenance strategies .
Application Areas
The EPRO MMS6110 is widely deployed in industries reliant on high-speed rotating equipment. In power generation, it safeguards steam and gas turbines by monitoring vibration trends to prevent catastrophic failures. For oil and gas applications, the module protects pipeline compressors and pumps by detecting shaft oscillations indicative of imbalance or bearing degradation .
In manufacturing, the MMS6110 is used for gearbox, fan, and centrifugal pump monitoring, while its compliance with API 670 makes it suitable for safety-critical environments like chemical plants and water treatment facilities. Integration with EPRO’s diagnostic software (e.g., CMS) enables predictive maintenance across sectors such as metallurgy, marine propulsion, and renewable energy, enhancing operational safety and asset longevity .
