Typical Application Scenarios

✅ Oil & Gas Refineries & Offshore Platforms: Explosive atmospheres in Zone 0/1/2 classified areas demand intrinsically safe grounding. The 138257-01 provides the certified IS barrier required for safe vibration and proximity monitoring of compressors and turbines.

Power Plants (Steam & Gas Turbines): Turbine protection systems require robust earth continuity to prevent signal interference. This module ensures clean grounding across the entire 3500 Series rack, protecting critical speed and vibration channels.

✅ Chemical & Petrochemical Processing: ATEX and IECEx compliance is non-negotiable in chemical plants. The 138257-01 satisfies international hazardous area directives while supporting heavy-duty continuous operation.

Mining Operations: Underground environments with methane or coal dust hazards require IS-certified grounding for conveyor systems, crushers, and ventilation fans. This module delivers the required safety margins.

✅ LNG & Cryogenic Facilities: Low-temperature operating range (-30°C to +65°C) makes the 138257-01 suitable for cryogenic process monitoring where standard modules may fail.
