GE Electric | DS200SHVMG1AFE | Safety Hazardous Vibration Monitor Module
Product Description:
The GE DS200SHVMG1AFE is a Safety Hazardous Vibration Monitor Module for Speedtronic Mark V turbine control systems. It provides real-time monitoring and protection against excessive vibration/shock in turbine-generator sets, triggering emergency shutdowns (ESD) when predefined safety thresholds are exceeded to prevent catastrophic mechanical failure.

Key Features:
- Multi-Sensor Support – Interfaces with seismic, eddy-current, and IEPE sensors.
- Dynamic Signal Analysis – FFT-based spectral processing for fault diagnosis.
- Phase Reference Input – Syncs with keyphasor signals for imbalance detection.
- Redundant Trip Paths – Independent ESD1/ESD2 relays for fail-safe operation.
- Waveform Capture – Stores vibration transients pre/post-trip for root-cause analysis.
- Sensor Health Monitoring – Detects open/short circuits in sensor wiring.
Primary Function & Purpose:
Continuously measures turbine shaft/bearing vibrations and triggers safety shutdowns within milliseconds to prevent:
- Rotor blade fatigue
- Bearing seizure
- Catastrophic rotor imbalance
Typical Applications:
- Gas/Steam Turbines – Overspeed vibration protection during startups.
- Compressor Trains – Anti-surge monitoring in oil/gas pipelines.
- Hydroelectric Generators – Runaway speed detection.
- Industrial Fans/Pumps – Mechanical looseness monitoring.
- Nuclear Plant Turbines – Seismic event response.
Application Fields:
Critical for rotating machinery protection in:
- Power Generation: Combined-cycle plants, peaker units, cogeneration facilities.
- Oil & Gas: Offshore platforms, LNG compressor stations.
- Heavy Industry: Steel mill blowers, pulp & paper turbines.
- Marine: Turbine-driven propulsion systems.
