Whether monitoring toxic gases in parts per million (ppm), oxygen depletion, or explosive hydrocarbons up to 100% of the Lower Flammable Limit (LFL/LEL), the XNX platform delivers an integrated safety solution. Its ruggedized construction carries extensive worldwide hazardous area certifications, making it a standard choice for heavy industrial sectors. Key Technical Specifications XNX™ Universal Transmitter - Automation | Honeywell
The XNX Universal Gas Transmitter is a cornerstone of modern industrial gas detection, embodying the "4 Top" qualities that industries need today: universal flexibility, robust safety, ease of use, and intelligent analytics. It's more than a simple sensor; it's a smart, connected safety device that collects critical data, feeds into powerful analytics platforms like Honeywell's Uniformance Suite, and helps organizations move from reactive alarm response to proactive safety management.
The stands as a premier benchmark platform for fixed industrial gas detection systems. Developed by Honeywell Analytics, this versatile transmitter simplifies hazardous gas monitoring across demanding sectors like oil and gas drilling, chemical manufacturing, and wastewater treatment.
To help you decide, here is a comparison of the XNX’s strengths and a few considerations: xnx xnx honeywell analytics 4 top
: It supports Electrochemical, Infrared (point and open-path), and Catalytic Bead gas monitors on a common platform.
Using one platform for all gas types reduces training and spare parts inventory.
Suddenly, the tablet chirped an error.
The third top feature is the device’s modular design, which includes three interchangeable metal housing options: Aluminum, 316 Stainless Steel, and a specialty epoxy-coated version for corrosive environments. This allows engineers to deploy the same core "XNX" logic across an entire facility, using ruggedized stainless steel for acid-wash bays and lighter aluminum for general-purpose areas. The "4" in our keyword might also refer to the four main connection options: Modbus, HART, 4-20 mA, and relay outputs, offering top-tier connectivity to any PLC or DCS.
: Features standard 4-20mA with HART . Optional modules include Modbus over RS-485 , Foundation Fieldbus , and up to three internal relays for alarm and fault indication.
It provides industry-standard 4-20mA with HART® as standard, alongside options for Modbus® and FOUNDATION® H1 Fieldbus, allowing integration into almost any control system. Whether monitoring toxic gases in parts per million
: Operators interact with the transmitter via a large, backlit, multi-lingual LCD screen using magnetic wands. This allows non-intrusive configuration in hazardous zones without opening the enclosure and triggering hot-work permits. 2. The Four Sensor Configurations Go to product viewer dialog for this item.
The "Universal" in its name refers to its ability to support the three major gas sensing technologies on a single platform: For toxic gases (e.g., ) and oxygen. Catalytic Bead (mV): For flammable gases (0-100% LEL).
