XNX Universal Gas Transmitter

The Universal Gas Transmitter XNX can accept all inputs from various Honeywell Analytics gas sensors. It uses standard 4-20mA or HART wiring and works with several communication protocols (Modbus, Fieldbus, etc.). Its multilingual backlit LCD provides all necessary status information in text, numbers, and icons.

  • Compatible with all Honeywell Analytics local and remote sensors
  • International approvals for use in hazardous areas (ATEX, UL, CSA)
  • Multiple communication protocols (Hart, Modbus, Fieldbus, etc.)
  • Multiple input and output options (linear, digital)
  • Robust aluminium alloy or stainless steel housing
Additional information

The universal gas transmitter XNX has three input cards: a millivolt card for explosive gas sensors, an EC card for electrochemical sensors, and an IR card for infrared sensors. The unit also offers a wide output options range: 4-20mA, HART, Fieldbus, Modbus RTU communication, and three fully configurable relay outputs.

It is compatible with Honeywell Analytics' entire range of fixed industrial gas sensors such as the Searchline Excel linear barrier, Searchpoint Optima Plus IR sensors, or the classic Sensepoint sensors. It is ATEX, UL, and CSA compliant.

The unit is set up with a non-intrusive magnetic switch, and sensor changes can be carried out under power in ATEX areas without intervention needed. For calibration, periodic checks, or gas tests of gas detectors, we offer a wide range of calibration gases in disposable cylinders that meet the ISO6142 standard
