Honeywell XNX Universal Transmitter

Basic information

Product Name: XNX Universal Transmitter

Core features: Compatible with all Honeywell gas sensor technologies, supporting multiple industry standard output signals, suitable for various gas detection scenarios, with advantages such as flexibility, universality, and global certification.

Product advantages

Flexibility

Compatible with all Honeywell gas sensor technologies, the best sensor technology can be selected for each application.

Supporting multiple industry standard output signals, able to adapt to changes in on-site requirements and adjust configurations, and preparing for future new output standards.

Universal transmitter platform

Simplify installation and reduce costs, minimize training time and expenses, reduce the possibility of misreading information and making incorrect changes to settings, and reduce maintenance, spare parts inventory, and costs.

Global certification

Obtained certifications in Europe, the United States, Canada, and other regions, compliant with ATEX, UL, and CSA standards, as well as ATEX, UL, and CSA performance certifications, meeting the IEC61508 SIL 2 standard.

Ease of Use

Equipped with an easy to read multilingual backlit LCD, displaying information through text, bar charts, numbers, and icons.

Supports local or remote sensor installation options, with the option to choose between current injection, current pulling, or isolated 4-20mA output to accommodate preferred wiring topology.

Standard equipped with HART ®  Communication function, convenient for remote diagnosis and configuration.

Reduce operating costs

Fully configured with non-invasive magnetic switches, no thermal work permit required.

Hot swappable toxic gas and oxygen sensor cartridge, catalytic and infrared sensors are repairable and automatically suppress during maintenance.

Friendly installation

Built in surface mount earbuds or optional pipe or ceiling mount brackets.

There are 5 M25 or three-quarters “NPT cable/conduit/sensor entrances, and the plug-in” POD “module can be removed for easy access to the terminal area. The detachable plug/socket terminal block is convenient for wiring.

Typical application scenarios

Suitable for offshore oil and production platforms, oil and gas exploration and drilling, refineries, chemical and petrochemical plants, onshore oil and gas terminals, natural gas transportation, power stations, and other scenarios.

Sensor compatibility

Compatible with all industrial fixed gas sensors in Honeywell’s analytical instrument series, including Searchline Excel, Searchpoint Optima Plus, Sensepoint (HT and PPM), and Model 705. Please refer to the individual data manuals for each sensor for details.

Main components and configuration

Main components

POD: Personality, Options and Display module.

Shell: available in painted marine grade aluminum alloy or 316 stainless steel version, with explosion-proof performance.

Other: Intrinsic Safety (IS) Barrier (for optional local HART) ®  Interface and electrochemical sensor interface), installation earpiece, optional local IS HART ®  Input ports, cable entrances, etc.

Configuration

There are three basic personalities (configurations) that support different types of sensors:

MV (Millivolt) Personality: Used for all mV signal input sensors, such as MPD, Sensepoint HT, PPM, and Model 705.

EC (electrochemical cell) personality: used for XNX EC toxic and oxygen sensors.

IR (Infrared) Personality: Used for Searchline Excel open circuit and Searchpoint Optima Plus point infrared gas detectors.

Install options

Supports multiple installation methods, including vertical or horizontal pipe installation (using optional pipe mounting brackets), ceiling installation, surface installation, in pipe installation, and optional remote sensor installation kit for XNX EC sensors (other sensor accessories depend on the sensor type).
