XNX™ Transmitter

 Universal transmitter for toxic, oxygen and combustible gas detection

Resources


The XNX Universal Transmitter, now with HART EDDL, marks a new turn in gas detection from Honeywell Analytics. It supports the widest range of sensors on a common platform and offers a modular choice of inputs and outputs.

XNX is designed for flexible integration, simple installation, user-friendly operation and straight-forward maintenance. It is ideal for use with a range of gas monitoring controllers or industry standard PLCs. The introduction of our HART Enhanced Device Descriptor Language (EDDL) software provides users with an at-a-glance indication of the health of their gas detectors in the field.


XNX Universal Transmitter

XNX is an extremely flexible transmitter that can be configured to accept an input from any of the Honeywell Analytics range of gas sensor technologies. It can also be configured to provide a wide variety of industry standard output signals. This enables users to have a single type of interface to all their gas detection needs, even when different types of detectors are employed, to most effectively address the different gas detection applications on site.

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 futureproofed 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 the cost of installation. The common user interface makes operation faster to learn and easier to navigate, thus reducing the 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. 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.

Universal Gas Sensing and Communications Platform

The XNX’s powerful advanced communications module – including our new HART EDDL software – adds increased efficiency, functionality and flexibility to a gas detection network. XNX offers a variety of communication options to suit your industrial operation’s unique and changing needs. HART communication comes standard on the XNX — with optional EDDL — along with optional Modbus, Foundation Fieldbus or relays.

It can interface with a PLC and a host of other protocol compatible devices found in industrial applications. Unique to the XNX and Honeywell Analytics is our new HART EDDL software, which allows you to manage all of your HART devices’ advanced diagnostic data right from your PLC. With the XNX, you are freed from the need to add extra controllers, junction boxes, relays, monitors and other equipment accessories. The integration of our EDDL software also enables the XNX to work with a number of third-party distributed control systems (DCS).


XNX Universal Transmitter - Inputs & Outputs

LXNX has Worldwide hazardous area and
performance approvals and is housed in
a flameproof enclosure that is available in
either painted marine grade aluminum alloy
or stainless steel 316 versions. A large backlit
multilingual LCD clearly indicates the unit’s
status using a combination of text, digits and
icons. Users can modify its operation using
the LCD and magnet switches without ever
needing to open the unit. An optional local
IS HART® terminal port is also available.
Both enable one man, non-intrusive, operation
and reduce routine maintenance time and
costs. Local LEDs are also provided to indicate
the unit’s status at a glance.

XNX is compatible with all of the Honeywell Analytics range of industrial fixed gas sensors including Searchline Excel, Searchpoint Optima Plus, Sensepoint (HT and PPM) and Model 705. For further information on these sensors, please refer to their individual datasheets.

LThe Multi Purpose Detector (MPD) is a serviceable stainless steel sensor housing with plug-in catalytic and infrared sensor cartridges. The catalytic sensors measure flammable gases in the range 0-100%LEL and the infrared sensors measure Hydrocarbons in the range 0-100%LEL, or Methane 0-100%LEL (or 0-5%Vol) and CO2 0-5%Vol.

See the specifications section for full details of the MPD sensor. The XNX EC sensor is also a serviceable stainless steel sensor with a wide range of toxic and Oxygen plug-in sensor cartridges. The XNX EC sensor interface to the XNX transmitter is intrinsically safe, allowing the sensors to be ‘hot swapped’ without the need for a hot work permit. This reduces the cost of ownership by reducing the cost and time to service the detector.
