XNX-AMAV-NNCB1 | Universal Transmitter for Flammable Gas
Honeywell XNX series offers a flexible, low-maintenance gas detection platform. It integrates with digital bus systems, 4‑20 mA loops, and HART®. This model supports Searchline Excel, Optima, and generic 4‑20 mA sensors. The catalytic bead (CB1) sensor detects 0–100 %LEL flammables.
- Application: oil & gas, chemical plants, refineries, and industrial safety
- Output: 4‑20 mA with HART® for diagnostics and configuration
- Approvals: ATEX, IECEx, INMETRO – Zone 1/2 and 21/22
Manager’s Insight: The XNX-AMAV-NNCB1 reduces inventory complexity. One transmitter works with infrared, catalytic, and electrochemical sensors. The M25 entries and aluminium housing simplify installation in harsh zones. Use existing HART handheld tools for fast setup.

Expert Review – Why Choose This Detector?
The XNX‑AMAV‑NNCB1 stands out for its universal design. You only need one transmitter for multiple sensor types. The HART® communication enables remote calibration and diagnostics. Its aluminium body withstands corrosive environments. The 4‑20 mA output ensures compatibility with existing infrastructure. For plant managers, this means reduced spare parts and training costs.
FAQ – Frequently Asked Questions
- Which gases can this detector measure?
It measures flammable gases and vapours (0‑100 %LEL) with the catalytic bead sensor. - Can I use this with a PLC?
Yes. The 4‑20 mA output connects directly to any PLC or DCS. - Is the sensor field‑replaceable?
Yes. You can replace the CB1 sensor in minutes without special tools. - What is the maximum cable length?
Up to 1,000 metres with 4‑20 mA (depends on cable gauge). - Does it support remote calibration?
Yes, via HART® handheld communicator or host system. - What if I need a stainless steel version?
We offer SS316 painted as an option – contact us for details.
Selection Guide – Which XNX Model Do You Need?
- For flammable gases → choose CB1 (catalytic bead) as shown here.
- For toxic gases → choose electrochemical sensor (EC).
- For CO₂ or hydrocarbons → choose infrared (IR).
- Need HART diagnostics? This model includes it. No extra adapter required.
- For ATEX Zone 1 or IECEx – this unit is certified.
