Audit Alert: Non-Certified Pressure Sensor in Zone 1

During a recent Petrochem facility audit, we discovered our pressure sensor in the process control system lacked the required Ex d certification for Zone 1 hazardous areas. This non-compliant sensor posed a serious safety risk: in an explosion, the flameproof enclosure must contain flames and prevent ignition of the surrounding atmosphere. Without proper certification, containment was not guaranteed.

To meet ATEX and IECEx standards, we replaced it with the DR3431 explosion proof pressure transmitter. This ATEX certified sensor features an Ex d flameproof enclosure that safely contains any internal explosion, preventing flame propagation. The rugged, heavy-duty housing withstands harsh conditions, while wide pressure and temperature ranges ensure reliable operation across various scenarios. It is suitable for both Zone 1 and Zone 2 environments.

Key Specifications

• ATEX and IECEx certified for hazardous areas
• Explosion-proof (Ex d) flameproof enclosure
• Rugged, heavy-duty housing
• Wide pressure and temperature ranges
• Suitable for Zone 1 and Zone 2 environments

Why It Works
The Ex d design relies on a robust enclosure that can withstand an internal explosion without rupturing. Flames are cooled as they pass through narrow gaps in the enclosure joints, preventing ignition of the external hazardous atmosphere. This physical principle ensures safety even in the worst-case scenario.
