Honeywell XNX XNX-UTAV-MNIV1 – MPD IR methane 0–100 %LEL, mV, UL, Aluminium, 3/4" NPT

XNX-UTAV-MNIV1 is a factory-configured Honeywell XNX with MPD infrared methane 0–100 %LEL, mV personality, UL / cUL, 4 × 3/4" NPT, LM25 aluminium (painted), Modbus RTU + 4–20 mA HART, no local HART port. It is the SKU for gas-transmission compounds and biogas roofs where catalytic poison or oxygen-free streams rule out CB1.

Why this personality / sensor

Methane is lighter than air and rises to roof vents. Dual-beam MPD IR does not need oxygen and ignores silicones. Mount high, under eaves or at the compressor-hall ridge, and keep the optical window out of wash-down.

Personality and replaceable parts

XNX-UTAV-MNIV1 uses the mV personality (MPD catalytic / MPD IR) board and mates with Honeywell MPD catalytic bead or MPD infrared sensors. Factory-fitted with MPD IR methane 0–100 %LEL. Spares live on product-3991. Do not substitute Sensepoint XCD cartridges on XNX.

Typical applications

City-gate stations, LNG boil-off rooms and anaerobic-digester roofs need a methane-specific IR point. XNX holds the trip while operators stay outside the classified shed.

Installation and wiring

Wall-mount XNX-UTAV-MNIV1 (LM25 aluminium (painted), approx. 2.8 kg) on a rigid stand sized for that mass. This SKU uses 4 × 3/4" NPT entries—glands must match; do not retap XNX-UTAV-MNIV1. Land XNX-UTAV-MNIV1 4–20 mA HART per the loop drawing; relays/Modbus/FFB exist only on the matching option board. Magnetic-wand menus on the XNX-UTAV-MNIV1 lid stay non-intrusive. Park the XNX-UTAV-MNIV1 methane IR at the ridge and out of wash-down.

FAQ

Can I retrofit Foundation Fieldbus on XNX-UTAV-MNIV1 after it ships?
No. XNX-UTAV-MNIV1 is the Modbus RTU option board. FFB is a different sales option (XNX-UTAV-FNIV1), not a jumper on this lid.
Local HART?
Depends on the local-HART digit — do not confuse with other options.
Comms options?
Relays, Modbus, Foundation Fieldbus etc. depending on order.
Calibration?
Per fitted sensor and target gas.
Lead time?
Lot-based.
