Function

The Honeywell XNX acts as the central transmitter for fixed gas detection systems. It receives signals from connected gas sensors, continuously monitors gas concentrations, displays readings locally, and transmits alarm and measurement data to plant control systems. Its universal architecture allows users to standardize on a single transmitter platform while supporting multiple sensor technologies and gas types throughout a facility.

Typical Applications

• Oil & Gas Production Facilities
• Offshore Platforms
• Petrochemical Plants
• Chemical Processing Facilities
• Refineries
• LNG Terminals
• Power Generation Plants
• Water Treatment Facilities
• Hazardous Area Gas Monitoring Systems
