Universal Transmitter that supports a wide range of sensors
The Honeywell XNXTM Universal Transmitter supports the widest range of sensors including toxic, oxygen and combustibles on a common platform and offers a modular choice of inputs and outputs (saving customers time and money).
There are three versions of the Honeywell XNX available: Electrochemical, Infrared and Catalytic Bead. (The IR and Electrochemical versions require the purchase of a compatible sensor separately)
Featuring:
- Flammable gas detection 0 to 100% LFL/LEL
- Flexible operation options
- Minimal training required
- Material: LM25 aluminium, painted (SS316 painted optional)
- Temperature: -40° to +65°C / -40° to +150°F (sensor dependent)
- Humidity: 20 to 90% RH (non-condensing)
- Explosion Proof Transmitters

XNX's advantage comes from its 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.
Honeywell's XNX - Electrochemical, Infrared and Catalytic Bead gas monitors use 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, the 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 aluminium, with a marine-grade coating. Five threaded ports, available in metric or NPT versions, and ruggedised 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.
Electrochemical
- Proven electrochemical sensing technology
- Surecell™ electrochemical cells are ideal for hot and humid environments
- Long-life sensing cells (typical >2 years)
- Patented ‘Reflex’ sensing element verification diagnostics
- Sensor recognition software auto-configures transmitter
- Plug and play factory configured sensors
- Intrinsically safe sensor connection permits hot-swap, reducing downtime
Catalytic Bead
- Supports Honeywell Analytics 705, 705HT, Sensepoint, Sensepoint HT and MPD sensors
- Fast response to a wide range of hydrocarbons and flammables
Infrared (Open Path IR, Point IR, IR Cell)
- Supports Honeywell Analytics Searchline Excel, Searchpoint Optima Plus
- Failsafe operation
- Fast speed of response
- Reduced routine maintenance
- Immune to catalytic poisons
- Long operating life
- Works in inert atmospheres
