Honeywell XNX transmitter for gas detection supports catalytic bead, electrochemical cell and infrared sensors on a common platform. One gas detection transmitter, hundreds of inputs, with HART and 4-20 mA outputs standard.

Reduce your inventory with a more flexible transmitter. One Honeywell XNX universal transmitter supports catalytic bead, electrochemical cells, and infrared. XNX comes standard with 4-20 mA and HART® outputs, and can easily integrate into a Modbus RTU network.

  • Universal transmitter takes any sensor input, with safety checks in configuration and setup: Electronics designed to confirm sensor type before operation, reducing installation and operation errors
  • Dual reservoir electrochemical cells, dual-compensated optics for point infrared, plus catalytic bead, open path IR, and IR cells
  • 4-20 mA with HART® standard; Modbus RTU communications plus optional internal relays for diagnostics and alarming
  • Better price-to-performance ratio than competitors' comparable units
  • Optional local IS port for handheld HART communicator. Compatible with the Meriam MFC 5150 HART® Handheld Communicator.
  • Easy gas and sensor readings with large backlit easy-to-view LCD display offers visual icons, colored buttons and text
  • NEMA 4X/IP65 painted aluminum or stainless steel enclosure
  • UL/CSA approved for use in Class I, Div 1 areas
  • SIL-2 capable
  • Made in Lincolnshire IL, so factory tech support is right in our back yard

Model Selection Guide

Use this table to find the right model for your application. Don't see the option or configuration you need? Call a Lesman sales specialist at 800-953-7626. Orders placed before 3PM central time for in stock models ship the same day.

Start by building your XNX transmitter. Follow the availability column for help making your selections.

If you choose an integral MPD Millivolt sensor, a complete XNX transmitter model number will look like this: XNX-UT_ _ - _ _ _ _ - _ _ _ _ _.  If you choose a remote sensor, the base model number will look the same. Then, you'll  order an electrochemical cell sensor, an infrared or 4-20 mA sensor input, or a remote MPD sensor separately.
