A Gulf Coast refinery needed to perform hot work (welding) on a crude oil tank undergoing cleaning. They deployed four units with 4-gas sensors plus PID. Analytics were streamed to a central tablet via the Honeywell Connect app. During the job, the PID detected rising benzene levels (0.5 ppm) from residual vapors not caught by LEL or H2S sensors. Work stopped, ventilation increased, and the team adjusted the permit. This is “analytics 4 hot” in action – not just detection but intelligent response.
represents a paradigm shift in industrial safety. By combining universal sensor support with robust environmental resilience and advanced digital communication, it provides a cost-effective and scalable solution for modern gas detection. Whether managing a single point of detection or a complex networked system, the XNX ensures that personnel and assets remain protected under the most demanding industrial conditions.
: The transmitter operates reliably from -40°C to +65°C (-40°F to +150°F), making it suitable for both arctic and desert conditions. Installation and Maintenance
Connect a nominal 24V DC (16–32V DC range) power source. Catalytic bead sensors draw significant current because the active bead must be heated to induce surface oxidation of the target gas. Ensure the power supply can handle the peak startup inrush current.
The primary strength of the Honeywell XNX lies in its concept of universality. In the past, gas detection systems were often siloed; different gases required different types of transmitters, and integrating them into a centralized control system could be cumbersome. The XNX solves this problem by acting as a single hub capable of communicating with various sensor types. It seamlessly integrates with Honeywell’s Searchline Excel open-path gas detectors, Searchpoint Optima Plus infrared point detectors, and standard catalytic and electrochemical cells. This interoperability simplifies inventory management for facilities and reduces the training burden on technicians, who only need to familiarize themselves with one interface rather than a multitude of disparate systems.
The is a modular gas detection platform designed to support a wide range of Honeywell Analytics sensors, including electrochemical, infrared, and catalytic bead technologies. A key feature for demanding environments is the ability to "hot swap" toxic and oxygen sensor cartridges, allowing for sensor replacement in hazardous areas without powering down the unit.
