Honeywell XNX XNX-UTSV-NHNNN – no sensor (transmitter body), mV, UL, 316SS, 3/4" NPT
XNX-UTSV-NHNNN is a Honeywell XNX universal transmitter body with the mV personality, UL / cUL, 4 × 3/4" NPT entries, 316 stainless steel, 4–20 mA HART only (no option board), local HART port on the transmitter, and no MPD sensor in the carton. Order it when the field later fits an MPD catalytic or MPD IR head (CB1 / IV1 / IF1 / IC1) instead of a factory-configured detector.
Same sensor, swap enclosure/approval: aluminium XNX-UTAV-NHNNN, 316SS XNX-UTSV-NHNNN, other approval XNX-AMSV-NHNNN. XNX-UTAV-NHNNN · XNX-UTSV-NHNNN · XNX-AMSV-NHNNN

Why this personality / sensor
The mV personality is the millivolt interface for Honeywell MPD heads. Catalytic and MPD IR share that board; an IR Optima/Excel head will not talk to this SKU, and an electrochemical cell needs the EC personality. Buy a body when the sensor slate is still open or when you stock transmitters separately from MPD cartridges.
Personality and replaceable parts
XNX-UTSV-NHNNN uses the mV personality (MPD catalytic / MPD IR) board and mates with Honeywell MPD catalytic bead or MPD infrared sensors. This SKU ships without a sensor; order the head by gas. Spares live on product-3991. Do not substitute Sensepoint XCD cartridges on XNX.
Typical applications
Typical body SKUs sit in a warehouse next to mixed MPD stock: pump rooms that may take catalytic LEL, biogas roofs that need methane IR, LPG pits that need propane IR, and inerting cabinets that need CO₂. The transmitter is already certified and threaded; you only mate the MPD later.

Installation and wiring
Wall-mount XNX-UTSV-NHNNN (316 stainless steel, approx. 5.0 kg) on a rigid stand sized for that mass. This SKU uses 4 × 3/4" NPT entries—glands must match; do not retap XNX-UTSV-NHNNN. Land XNX-UTSV-NHNNN 4–20 mA HART per the loop drawing; relays/Modbus/FFB exist only on the matching option board. Magnetic-wand menus on the XNX-UTSV-NHNNN lid stay non-intrusive. XNX-UTSV-NHNNN is a body: wall-mount the transmitter first and mate the head after the personality is confirmed—do not buy a configured SKU until the gas is frozen.
FAQ
- Which sensors?
- CAT/IR/EC etc. via personality/sensor configuration digits.
- Spares?
- Use the family matrix for heads and accessories.
- Is XNX-UTSV-NHNNN a complete gas detector?
- No. XNX-UTSV-NHNNN is electronics and enclosure only. A configured detector has a three-character sensor code such as CB1 instead of NNN.
- Alu/SS?
- Choose by corrosion/weight; enclosure digit is in the P/N.
- Local HART?
- Depends on the local-HART digit — do not confuse with other options.
