Honeywell SPXNXSS316 XNX Universal Transmitter 316L Stainless Steel Housing Multi Gas Detector

SPXNXSS316 | XNX Universal Transmitter Fixed Gas Detector with Upgraded Housing

XNX universal transmitter in 316L stainless housing, accepting catalytic, infrared and electrochemical sensor modules.

Why the Housing Upgrade Matters

Most fixed detector failures in the field are not sensor failures — they are enclosure failures. Salt-laden coastal air, hydrogen sulfide, acid mist, washdown jets and UV exposure attack painted aluminium housings long before the sensing element reaches end of life. This SPXNXSS316 answers that problem at the metal level, not with a coating touch-up.

Detection Performance

• Sensor technology: interchangeable catalytic, infrared and electrochemical modules
• Detection range: 0-100% LEL, 0-25% vol oxygen, ppm toxic ranges
• Output signal: 4-20 mA, Modbus RTU, HART, three relay contacts
• Calibration: non-intrusive magnetic switch through the sealed housing, no cover removal required

Housing and Installation Highlights

• One stainless transmitter platform accepts catalytic, infrared and electrochemical modules, cutting spares holding
• Stainless bezel protects the LCD from UV yellowing and solvent attack
• Three gland entries allow daisy chained Modbus loops without extra junction boxes
• Non-intrusive magnetic interface means configuration changes need no cover removal

Typical Applications

• Multi point plant wide detection networks
• Refinery and petrochemical units
• Gas turbine enclosures
• Water treatment chlorine rooms
