XNX Universal Transmitters

XNX Universal Transmitters
Scope Of Work Fixed Gas Detection

Product Details

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

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.
