Description
The EPRO RSM020-1 is a high-performance, 4-channel dynamic signal acquisition module engineered for continuous vibration monitoring and machinery protection in critical rotating equipment. As a core component of EPRO’s MMS (Machine Monitoring System) platform—widely deployed in power generation, oil & gas, and heavy industry—the RSM020-1 captures high-fidelity analog signals from proximity probes, accelerometers, and velocity sensors with exceptional noise immunity and time-synchronized precision. Designed for integration into both new installations and life-extension retrofits, it transforms raw sensor data into real-time diagnostics including shaft orbit, Bode plots, cascade spectra, and overall vibration trends—enabling early detection of imbalance, misalignment, bearing wear, and resonance conditions before catastrophic failure occurs.
Application Scenarios
At a 1.200 MW combined-cycle power plant in Germany, repeated false alarms from an aging turbine monitoring system led to unnecessary shutdowns and lost revenue. After upgrading to the EPRO RSM020-1. engineers gained access to clean, anti-aliased waveforms with true synchronous sampling across all four channels. Within weeks, they identified a developing 1X imbalance masked by electrical noise in the legacy system. Corrective balancing during the next planned outage prevented a potential forced outage estimated at €3.2 million. “The RSM020-1 didn’t just give us data—it gave us confidence,” said the plant’s chief vibration analyst. “Now we act on facts, not noise.”
Note: Fully compatible with EPRO MMS 6000 and MMS 7000 software suites for advanced diagnostics and alarm management.
Technical Principles and Innovative Values
Innovation Point 1: True Synchronous Sampling – All four channels on the RSM020-1 are sampled simultaneously using a shared clock, preserving phase relationships essential for accurate orbit plots and directional vibration analysis—critical for diagnosing rotor dynamic issues.
Innovation Point 2: Adaptive Anti-Aliasing – Unlike fixed filters that degrade signal fidelity, the RSM020-1 dynamically configures its anti-aliasing filter cutoff based on user-defined analysis bandwidth, ensuring optimal noise rejection without distorting transient events.
Innovation Point 3: Embedded Signal Processing – Onboard FPGA performs real-time RMS, peak-to-peak, and frequency-domain calculations, reducing host CPU load and enabling faster alarm response—vital in protection applications.
Innovation Point 4: Redundant Communication Paths – Dual Ethernet ports support ring or star topologies with automatic failover, ensuring uninterrupted data flow even during network maintenance or cable damage.
Application Cases and Industry Value
In a Middle Eastern LNG compression train, the EPRO RSM020-1 monitors two 20 MW centrifugal compressors operating 8.760 hours/year. Despite ambient temperatures exceeding 50°C and intense EMI from VFDs, the modules have delivered uninterrupted service for over six years. “We’ve caught three bearing defects in their incipient stage—all thanks to the clean waveform data from the RSM020-1.” noted the site’s reliability manager.
Similarly, at a nuclear auxiliary feedwater pump system in Scandinavia, the RSM020-1 forms part of a condition-based maintenance program aligned with EPRI guidelines. Its ability to log raw time-waveform data at high resolution enabled root-cause analysis of a rub-induced thermal bow—preventing a potential safety-related trip.

Installation, Maintenance, and Full-Cycle Support
Installing the EPRO RSM020-1 requires mounting in a compatible MMS rack (e.g., MMS 6811) and connecting shielded twisted-pair cables from field sensors. For optimal noise immunity, sensor shields should be grounded only at the module end, and cables routed away from AC power lines. The module supports hot configuration via Ethernet—no need to power down during setup.
Maintenance is largely predictive: the MMS software continuously evaluates signal quality, sensor health, and alarm thresholds. If a probe drifts out of calibration or a cable develops a short, the system flags it before data integrity is compromised. With no moving parts and industrial-grade components, the RSM020-1 typically operates for a decade or more without hardware intervention.
