XNX is an extremely flexible gas transmitter that can be configured to accept an input from any of the Honeywell Analytics range of gas sensor technologies.

A key feature is that it comes with HART over 4-20mA as standard. This enables users to have a single type of interface to all their gas detection needs, even when different types of detectors are employed.

Supports the widest range of sensors on a common platform and offers a modular choice of inputs and outputs (saving customers time and money).

Features & Benefits

• Flammable gas detection 0 to 100% LFL/LEL
• Flexible operation options
• Minimal training required

Quick Specs

• Material: LM25 aluminum, painted (SS316 painted optional)
• Temperature: -40° to +65°C / -40° to +150°F (sensor dependent)
• Humidity: 20 to 90% RH (non-condensing)

Product Overview

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.
