Honeywell XNX Universal Transmitter

The Honeywell XNX Universal Transmitters main advantage comes from a simple-to-use, low-maintenance universal platform that works with other safety equipment on a digital bus system. This includes Honeywell Analytics own Searchline Excel, Optima or other gas detectors. Honeywell XNX Universal Transmitters integrate seamlessly with industry standard PLCs and third-party gas monitoring controllers.

XNX Universal Transmitters support Electrochemical, Infrared and Catalytic Bead gas monitors, and uses standard 4-20mA wiring and HART. Options include Modbus, Fieldbus up to three relays and a local Hart Adapter for configuration and diagnostics using existing HART handheld devices.

With 200+ unique configurations, XNX Universal Transmitters satisfy 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 aluminium, 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.

Precision Safety is a supplier of a wide range of Fixed Gas Detection or Permanent Installed Detectors in Australia and New Zealand. We supply stand-alone detectors and monitors as well as gas detection controllers integrated into plant PLC and control systems.

A universal transmitter compatible with all Honeywell Analytics gas sensor technologies

The most effective gas detection systems often employ a variety of detection technologies including point flammable detectors (both catalytic and infrared type), toxic and Oxygen electrochemical cell type detectors and open path infrared detectors.

XNX provides a common transmitter interface to all of these and can be configured to provide industry standard signal outputs to match the individual requirement of each application or the preferred site standard.

If site output standards change, XNX can be reconfigured to provide the new required output. XNX has also been future-proofed by having the ability to have other output modules fitted as new output standards are developed and adopted by industry.

Having a common transmitter platform for all your gas detectors brings further benefits. Common tools and installation methods simplifies and reduces cost of installation.

The common user interface makes operation faster to learn and easier to navigate, thus reducing time needed for training as well as reducing the chance of incorrectly interpreting messages or incorrectly changing settings. Common spare parts also mean reduced maintenance spares stock levels and cost for all detectors.

Do More With Less!

XNX allows you to apply the most appropriate gas detection technologies for each application, standardise the interface to those detectors and has the flexibility to provide the required signal outputs. With XNX the answer is always yes.
