Honeywell XNX Universal Gas Transmitter

Honeywell XNX Universal Gas Transmitter — Toxic and Combustible Gas Detection for Saudi Arabian Petrochemical and Refinery Operations

The Honeywell XNX Universal Gas Transmitter is a flexible platform designed for toxic and combustible gas detection across Saudi Arabia's oil & gas facilities. Compatible with Honeywell Sensepoint and Searchpoint IR sensors, the XNX handles both toxic gas monitoring (H2S, CO, NH3) and combustible gas detection (LEL monitoring) with a single transmitter platform.

Saudi Aramco's Fire and Gas (F&G) detection philosophy requires gas detection coverage in all classified areas with transmitter output to the F&G system. The XNX's universal design covers all gas detection requirements across a plant from a single platform — reducing training, maintenance, and spare parts complexity.

Key Features

Universal Platform: Accepts mV (catalytic bead), IR (non-dispersive IR), and electrochemical toxic gas sensors — one transmitter platform covers all gas types, simplifying procurement and maintenance for Saudi plant operators.

3-Wire 4–20 mA Output: Standard industrial signal compatible with all DCS and PLC systems found across Saudi Aramco and SABIC facilities — direct wiring to Emerson DeltaV, Honeywell Experion, and Siemens PCS 7.

HART and RS-485 Modbus: Digital communications for remote calibration, sensor status monitoring, and asset management — enabling proactive maintenance before sensor failure.

Explosion-Proof Housing: ATEX and IECEx certified explosion-proof housing for Zone 1 and Zone 2 hazardous areas — suitable for all Saudi Aramco classified locations.

Applications in Saudi Arabia

Aramco Gas Plant F&G Coverage: XNX with H2S Sensepoint sensors provides perimeter gas detection around amine gas treating units — any H2S leak is detected and reported to the F&G system within 5 seconds.

SABIC Polymers Plant: XNX with IR sensors monitors LEL in polyethylene extrusion areas where hydrocarbon vapors from pellets can accumulate — preventing explosive atmosphere formation.

Frequently Asked Questions

Q1: What gas sensors are compatible with Honeywell XNX? Honeywell Sensepoint (mV/catalytic), Searchpoint IR Plus (IR combustible gas), and Honeywell toxic gas sensors (H2S, CO, NH3, SO2, CL2) are all compatible. RAZZ supplies the complete range with XNX transmitter.

Q2: Is XNX approved for Saudi Aramco hazardous areas? Yes — XNX carries ATEX Zone 1 and IECEx Zone 1 certification accepted by Saudi Aramco for Class I Division 1 equivalent locations.

Q3: What is the expected sensor life for XNX in Saudi Arabia? Catalytic bead sensors: 2–3 years in normal service. IR sensors: 5–7 years. Electrochemical toxic sensors: 1–3 years depending on gas type and exposure level. RAZZ recommends annual calibration and sensor replacement on schedule.
