The XNX™ Universal Transmitter, now with HART EDDL/DTM, 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) & Device Type Manager (DTM) software provides users with an at-a-glance indication of the health of their gas detectors in the field.
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.
