The cornerstone of the XNX platform is its modular "personality" board strategy. Instead of requiring dedicated transmitters for different classes of gases, a single XNX enclosure can be configured for three primary sensor types: XNX™ Universal Transmitter - Automation | Honeywell
Accessing the internal menus requires a magnetic wand and a passcode:
| Feature | XNX Universal Transmitter | Other Fixed Gas Detectors | | :--- | :--- | :--- | | | Catalytic Bead, EC, IR (Supports up to 3 technologies) | Often limited to 1 or 2 sensor technologies. | | Communication | 4-20mA / HART (Standard), Modbus / Fieldbus (Optional) | Typically 4-20mA only; HART may be extra. | | Configuration | Non-intrusive via magnetic switches | Often requires opening the housing (lowers safety). | | Housing Options | Aluminum (painted) or Stainless Steel 316 | Typically aluminum only (requires paint for marine). | | Operational Display | Large backlit LCD with icons and text | Small segmented numeric display or no display. | | Safety Certification | SIL 2 capable (IEC61508) | Varies; often standard, not always certified to IEC61508. | For cleanrooms, the PID capability in Analytics 4
: Rated at NEMA 4X / IP66 for complete protection against severe weather, dust, and water jets.
: Magnetic switches allow users to navigate menus and perform calibrations without opening the explosion-proof enclosure. Output Options : Standard 4-20mA with , with modular options for Modbus RTU Foundation Fieldbus , and local relays. www.detectoresymedidores.com Industrial Applications
Use cases
Because the user interface is consistent across all sensor types, maintenance personnel require less training to operate, calibrate, or troubleshoot the units.
Facility operators can use HART Enhanced Device Descriptor Language (EDDL) software to get an "at-a-glance" indication of the health of their gas detectors.
It supports multiple operation modes, including current sink, current source, and isolated current sink. | | Communication | 4-20mA / HART (Standard),
A Midwest refinery had 200+ Honeywell portable gas detectors (using 4-Series sensors). They were spending 20 hours per week manually downloading data. After implementing Honeywell’s cloud analytics, they:
