Emerson adds combustible gas detection to wireless gas monitoring platform
(WO) — Emerson has expanded the capabilities of its Rosemount 928 Wireless Gas Monitor by adding combustible gas detection, enabling operators to monitor lower explosive limit (LEL) levels in remote or difficult-to-access locations using WirelessHART communications.
The update allows the Rosemount 928 to measure combustible gas concentrations from 0% to 100% LEL, providing real-time monitoring and early warning of potential gas hazards without requiring additional power supplies or signal wiring.
According to Emerson, the enhancement is designed to help operators extend gas detection coverage into locations where traditional wired installations may be impractical or cost prohibitive.
“Adding combustible gas detection to the Rosemount 928 gives customers more flexibility as safety requirements evolve,” said Dave Ruhland, global flame and gas product manager for Emerson's measurement instrumentation business. “Facilities can extend their wireless gas detection strategy to include combustible hazards on existing WirelessHART platforms.”
The company said the sensor technology does not rely on consumable elements such as catalytic beads, which can degrade over time with repeated gas exposure. As a result, the system may support longer maintenance intervals and reduce recalibration requirements.
Combustible gas measurements are transmitted through Emerson's WirelessHART network, allowing operators to integrate additional monitoring points into existing safety programs while maintaining real-time visibility of gas conditions across facilities.
The update is intended for industrial sites where expanded gas detection coverage can improve safety and operational awareness, particularly in remote or hard-to-wire areas of oil and gas, refining and process facilities.
