EPRO SDM010: Multipurpose Monitoring Module

Product Description

The EPRO SDM010 is a versatile, multifunctional monitoring module designed for the continuous protection and condition monitoring of rotating machinery, such as turbines, compressors, pumps, and fans. As part of the renowned EPRO (now part of AMS) machinery protection ecosystem, this module serves as a configurable input channel that can accept signals from various transducer types, including proximity probes for vibration and position (eddy current), accelerometers, and velocity sensors. The primary function of the EPRO SDM010 is to condition these raw signals, compare them against user-configured alarm and trip setpoints, and provide both 4-20mA outputs for trending and relay outputs for machinery protection. Its flexibility makes it a cornerstone for building customized monitoring systems tailored to specific machine train requirements.

Product Parameters

  • Proximity Probe (eddy current): For radial vibration, axial position, speed, and phase.
  • Seismic Transducer: For velocity or acceleration.
• Input Channels: Typically a single channel per module.
• Outputs: 4-20 mA analog output proportional to the measured parameter, and relay outputs for Alert and Danger alarms.
• Dynamic Range: Wide input range suitable for various transducer sensitivities.
• Configuration: Set via front-panel buttons/display or PC software (e.g., ePCM).
• Power Supply: Powered from the monitoring rack.

Advantages and Features

The key advantage of the EPRO SDM010 is its high configurability, allowing one module type to serve multiple monitoring functions (vibration, position, speed), which simplifies spare parts inventory. It features dual alarm setpoints with independent relay outputs, enabling both early warning (Alert) and immediate shutdown (Danger) actions. The module provides excellent signal conditioning with adjustable filtering (e.g., for 1X RPM or broader frequency bands). Its robust design ensures reliable operation in harsh industrial environments with high electrical noise. The EPRO SDM010 integrates seamlessly into larger EPRO systems, allowing for centralized monitoring and data management, and supports comprehensive diagnostics for both the sensor and its own internal health.

Application Cases in Various Fields

This module is used wherever critical rotating machinery requires protection. In Power Generation, the EPRO SDM010 monitors turbine shaft vibration, eccentricity, and casing vibration. Within Oil & Gas, it protects centrifugal and reciprocating compressors on offshore platforms and in refineries, monitoring radial vibration and axial thrust position. For Petrochemical plants, it safeguards large pumps and fans. It is also essential in Marine applications for main engine and turbocharger monitoring, and in Heavy Industry for gearbox and mill motor protection.

Comparisons with Competing Products

Competing products include monitoring modules from Bently Nevada (3500/42M) and SKF (Multilog). The EPRO SDM010 is highly regarded for its user-friendly configuration, flexibility, and strong reputation in the power generation sector. Compared to simpler vibration switches, it provides continuous, high-fidelity measurement and trending. Compared to building a system from discrete components (separate signal conditioners, monitors, and relays), the integrated design of the EPRO SDM010 offers a more reliable, compact, and easier-to-maintain solution. Its primary strength is its application-focused design within a proven machinery protection framework.

Selection Suggestions and Precautions

1. Transducer Compatibility: You must configure the EPRO SDM010 for the specific transducer type (e.g., 8 mm probe, 100 mV/mil sensitivity) connected to it. Incorrect configuration will lead to inaccurate readings and improper alarm levels.
2. Gap Voltage/Setup: For proximity probes (eddy current), the correct gap voltage (-VDC) must be established during installation and set in the module. This ensures the probe operates in its linear range.
3. Alarm Setpoint Rationale: Alarm and Danger setpoints should be based on machinery manufacturer specifications, industry standards (like API 670), and historical operating data. Arbitrary settings can cause nuisance trips or fail to protect the machine.
4. Regular Calibration and Testing: Implement a schedule for functional testing of the monitoring loop, including the EPRO SDM010, its transducer, and wiring. This often involves using a portable calibrator to simulate vibration/position signals and verify the module’s response and relay actions.
5. Integration and Bypassing: Understand how the relay outputs are integrated into the machine’s shutdown circuit. If maintenance requires bypassing the EPRO SDM010, follow strict administrative controls (work permits) to prevent accidental machine startup without protection. Never disable protective functions without proper authorization and procedures.
