Honeywell XNX Toxic And Oxygen EC Sensors

The Honeywell XNX™ Toxic & Oxygen EC sensor is also a serviceable stainless steel sensor with a wide range of toxic and Oxygen plug-in sensor cartridges with three Global Compliances in ATEX/IEC, UL/CSA & CU-TR standard performance approval for use with the XNX Instrument.
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.
Product Overview
Honeywell XNX™ Universal Transmitter Gas Detectors are a simple-to-use, low-maintenance universal platform that works with other safety equipment on a digital bus system. The 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.
The Multi-Purpose Detector (MPD) is a serviceable stainless steel sensor housing with plug-in catalytic and infrared sensor cartridges. 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 XNX Transmitter has worldwide hazardous area and performance approvals and is housed in a flameproof marine-grade aluminium alloy enclosure. It 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.
The Honeywell XNX have five threaded ports, available in metric or NPT versions, and ruggedized mounting options. Instrumentation built on various sensing technologies can be attached locally to the transmitter or remotely via accessories.
