Emerson has added combustible gas detection to its Rosemount 928 wireless gas monitor, extending hazard visibility in remote or hard-to-wire industrial areas.
The updated device supports percent lower explosive limit (%LEL) monitoring over the WirelessHART platform, allowing users to monitor combustible gas hazards without additional power or signal wiring.
Rosemount 928 wireless gas monitor adds %LEL monitoring
The Rosemount 928 wireless gas monitor now supports measurements from 0% to 100% lower explosive limit. Emerson said this provides earlier warning and greater visibility of combustible gas hazards as conditions change.
The update expands the device beyond toxic gas monitoring into combustible gas detection, including applications where wired gas detection may be costly or impractical.
According to Emerson’s product information, the Rosemount 928 is designed for continuous monitoring and alerts for combustible or toxic gas leaks, using WirelessHART technology to extend coverage to remote, hard-to-reach or hazardous areas. Emerson’s Rosemount 928 product page confirms the device supports combustible and toxic gas monitoring over WirelessHART.
WirelessHART supports hard-to-reach locations
Secure WirelessHART communication transmits gas data in real time. Emerson said this enables deployment in areas where installing additional power or signal wiring would be difficult.
For water and wastewater operators, wireless gas detection may be relevant at remote pumping stations, enclosed treatment areas, chemical storage zones, biogas handling systems and other hazardous locations.
The technology is intended to complement existing gas detection programmes by helping teams add monitoring points where hardwiring would be logistically challenging or expensive.
Sensor design aims to reduce maintenance
Emerson said the combustible sensing technology is designed to reduce maintenance over time because it does not rely on consumable elements such as catalytic beads, which can degrade with repeated gas exposure.
The company said this can support longer service intervals and reduce the need for frequent recalibration.
Product data published by Emerson describes the Rosemount 928 as an integrated WirelessHART toxic and combustible gas monitoring solution with a tool-less, hot-swappable sensor. The Emerson product data sheet also states that the 928 is designed to extend gas detection coverage to remote installations.
Emerson says update supports safety coverage
Dave Ruhland, global flame and gas product manager for Emerson’s measurement instrumentation business, said: “Adding combustible gas detection to the Rosemount 928 gives customers more flexibility as safety requirements evolve. Facilities can extend their wireless gas detection strategy to include combustible hazards on existing WirelessHART platforms – simplifying installation and supporting reliable monitoring in more hard-to-reach areas across their facilities.”
The update is aimed at facilities seeking to expand combustible gas detection without extending wired infrastructure to every monitoring location.
