XNX-UTSV-NNIV1 Honeywell IR Gas Detector – 316SS, UL/CSA, HART Output

XNX-UTSV-NNIV1 – Stainless Steel Universal Transmitter

• Honeywell XNX platform – one transmitter, many sensors
• Accepts milli‑Volt inputs from MPD, Sensepoint, Model 705 HT, and PPM sensors
• Includes IR methane sensor – range 0‑100 %LEL (or 0‑5 %V/V)
• Output: 4‑20 mA with HART® as standard
• Housing: Painted 316 stainless steel – 5 x ¾″ NPT entries
• Approvals: UL / CSA for North American hazardous locations

Manager’s Insight – Why This Model?

This unit simplifies gas detection in one box. It works with mV sensors, so you can use existing MPD or Sensepoint heads. The 316SS body resists corrosion in offshore or chemical plants. HART® communication allows remote setup and troubleshooting. For plant engineers, it means less spare parts and faster maintenance.

Expert Review – Performance & Durability

The XNX‑UTSV‑NNIV1 stands out for its rugged stainless steel housing and flexible mV input. It accepts multiple sensor types, reducing the need for different transmitters. The IR methane sensor provides fast response and high accuracy. HART® enables easy calibration and diagnostics from the control room. For safety managers, this unit lowers total cost of ownership while maintaining reliable gas detection in harsh environments.

Frequently Asked Questions (FAQ)

• What gases can this model detect?
  It detects methane (CH₄) using the built‑in IR sensor. Range: 0‑100 %LEL or 0‑5 %V/V.
• Can I use this with existing MPD sensors?
  Yes. The mV input supports MPD, Sensepoint, and Model 705 HT sensors directly.
• Is the 316SS housing necessary?
  Yes for corrosive or salty environments. It provides better protection than aluminium.
• How do I calibrate the IR sensor?
  Use the HART® handheld or the local interface. Calibration gas is required.
• What about warranty and shipping?
  12‑month warranty. We dispatch within 12‑24 hours via FedEx, UPS, or DHL.

Selection Guide – Which XNX Model to Choose?

• For flammable gases (methane, propane) → choose IR sensor (this model).
• For toxic gases (CO, H₂S) → choose electrochemical sensor.
• For North America → choose UL/CSA approved (this model).
• For Europe / international → choose ATEX/IECEx version (XNX‑AMAV‑NNCB1).
• Need CO₂ measurement? See the XNX‑AMAV‑MNIC1 (IR CO₂ sensor).
