XNX Universal Gas Transmitter

Supports the widest range of sensors on a common platform and offers a modular choice of inputs and outputs, saving customers time and money on wiring and material costs, installation, maintenance and operation.

XNX's advantage comes from a simple-to-use, low-maintenance universal platform that works with other safety equipment on a digital bus system, including Honeywell Analytics’ own Searchline Excel, Optima or other gas detectors, industry standard PLCs and third-party gas monitoring controllers.

XNX supports Electrochemical, Infrared and Catalytic Bead gas monitors and uses standard 4-20mA wiring and HART; options include Modbus, Fieldbus (pending) up to three relays and a local Hart Adapter for configuration and diagnostics using existing HART handheld devices.

With 200+ unique configurations, XNX satisfies Class 1/Class 2 intrinsically safe, explosion-proof requirements in upstream/downstream oil, chemical, wastewater and other industries.

The enclosure is available in stainless steel or aluminum, with a marine-grade coating. Five threaded ports, available in metric or NPT versions, and ruggedized mounting options provide ultimate installation flexibility. Instrumentation built on various sensing technologies can be attached locally to the transmitter or remotely with the appropriate accessories.

The XNX user interface provides Alarm, Fault and configuration support via a large dot matrix display and LED indicators. Icons supported by seven language selections are used to ensure ease of operation around the world.

Pipe Mount Kit - 1226A0358
For use on pipes from 50-100mm (2-6 inches) in diameter. The kit includes: Pipe mount bracket, (2) carriage bolts, nuts and lock washers.

Remote EC Sensor Mounting Kit - SK3RMK
The remote sensor mounting kit (SK3RMK) allows the XNX EC sensors to be remotely mounted via an IS cable kit, up to 15 meters (50 feet) from the transmitter. The kit includes 15 meters of shielded cable, cable glands and remote terminal box. The cable can be cut to the required length and terminated at the remote terminal box.

Ceiling Mount Bracket Kit - 1226A0355
The optional ceiling mount bracket kit allows XNX to be mounted to a ceiling. The kit includes: (2) stainless steel ceiling mount brackets, bolts and nuts.

Duct Mount Kit - 3001A0408 and MPD Interface Adapter - 1226A0382
The duct mounting kit (3001A0408) can be used with the EC sensor to allow detection of flammable O2, CO, H2 and H2S gasses in ducts. When combined with the MPD interface adapter (1226A0382), the duct mounting kit can accommodate the MPD to detect flammable gases in a duct application. The duct mount kit includes the adapter, gasket and required fasteners. The MPD interface adapter includes only the adapter and requires the 3001A0408 duct mount kit.

Calibration Gas Flow Adapter
The calibration gas flow adapter is used to apply calibration test gas to the sensor. It push fills onto the bottom of the sensor and can be fitted without removing the weatherproof cover.
