Honeywell XNX XNX-AMAV-NHCB1 – MPD catalytic 0–100 %LEL, mV, ATEX, Aluminium, M25

XNX-AMAV-NHCB1 is a factory-configured Honeywell XNX gas detector: mV personality, MPD catalytic bead 0–100 %LEL, ATEX / IECEx (INMETRO on selected MPD SKUs), 4 × M25, LM25 aluminium (painted), 4–20 mA HART only (no option board), local HART port on the transmitter. Specify it for mixed hydrocarbon LEL points where infrared windows would fog or the stream is not methane/propane-specific.

Why this personality / sensor

A poison-resistant MPD pellistor sees combustion heat across a wide hydrocarbon mix, including species an IR filter misses. It needs oxygen and hates silicones. Mount above light-gas releases and below heavy vapours; keep silicone sealants off the sinter.

Personality and replaceable parts

XNX-AMAV-NHCB1 uses the mV personality (MPD catalytic / MPD IR) board and mates with Honeywell MPD catalytic bead or MPD infrared sensors. Factory-fitted with MPD catalytic 0–100 %LEL. Spares live on product-3991. Do not substitute Sensepoint XCD cartridges on XNX.

Typical applications

Pump rooms, filling gantries and compressor packages still standardise on catalytic LEL because the gas slate is mixed. XNX holds 4–20 mA HART into the ESD matrix; magnetic non-intrusive calibration keeps the flameproof lid closed.

Installation and wiring

Wall-mount XNX-AMAV-NHCB1 (LM25 aluminium (painted), approx. 2.8 kg) on a rigid stand sized for that mass. This SKU uses 4 × M25 entries—glands must match; do not retap XNX-AMAV-NHCB1. Land XNX-AMAV-NHCB1 4–20 mA HART per the loop drawing; relays/Modbus/FFB exist only on the matching option board. Magnetic-wand menus on the XNX-AMAV-NHCB1 lid stay non-intrusive. Keep silicones off the XNX-AMAV-NHCB1 pellistor; light hydrocarbons high, heavy vapours low.

Lot-based.
When should I swap XNX-AMAV-NHCB1 aluminium for 316SS?
Use XNX-AMAV-NHCB1 (aluminium, ~2.8 kg) in inland, painted plant. Coastal, splash and sour-water decks should move to stainless sibling XNX-AMSV-NHCB1.
