Emerson Expands Rosemount Wireless Gas Monitor for Advanced Hazard Detectio
Emerson has expanded the capabilities of its Rosemount 928 Wireless Gas Monitor, introducing combustible gas detection functionality designed to improve safety monitoring across oil and gas, refining, and process industries.
The latest enhancement enables operators to measure combustible gas concentrations from 0% to 100% of the lower explosive limit (LEL), providing real-time visibility into potential gas hazards without requiring additional power infrastructure or traditional signal wiring.
The update strengthens Emerson’s wireless safety instrumentation portfolio by allowing facilities to extend gas detection coverage into areas where conventional wired systems may be difficult, expensive, or impractical to install. Remote equipment locations, offshore facilities, storage areas, and distributed process units can benefit from additional monitoring points without major infrastructure modifications.
The upgraded Emerson Rosemount 928 Wireless Gas Monitor uses WirelessHART communication technology to transmit combustible gas measurements across existing wireless networks. This enables operators to integrate additional safety monitoring capabilities into current industrial systems while maintaining continuous awareness of changing gas conditions.
“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. He noted that the expanded capability allows facilities to enhance their wireless gas detection strategies while continuing to use established WirelessHART infrastructure.
Traditional gas detection installations often require extensive cabling, power supplies, and engineering work, particularly in remote or hazardous environments. Wireless solutions provide an alternative approach by reducing installation complexity and allowing operators to deploy monitoring devices in locations that previously lacked practical detection coverage.
The introduction of combustible gas monitoring also supports the broader industry movement toward connected safety systems, where field devices provide continuous operational data for faster response and improved risk management.
Emerson stated that the sensor technology used in the upgraded Rosemount 928 does not depend on consumable components such as catalytic beads, which can experience performance degradation after repeated exposure to gases. By reducing dependence on replaceable sensing elements, the technology may help extend maintenance intervals and reduce recalibration requirements.
For industrial operators, improved gas monitoring can play a critical role in preventing incidents and protecting personnel, assets, and production continuity. Early detection of combustible gas accumulation allows safety teams and automated systems to respond before conditions escalate into more serious hazards.
The expansion of wireless gas detection capabilities reflects a wider transformation in industrial safety automation. Modern facilities are increasingly adopting intelligent field instrumentation, wireless communication networks, and digital monitoring platforms to improve visibility across complex operations.
Emerson’s portfolio of process automation solutions, including DeltaV Safety Instrumented System technologies, demonstrates the industry’s shift toward integrated safety architectures where field devices, control systems, and operational data platforms work together to improve reliability.
The ability to add gas monitoring points without extensive wiring requirements is particularly valuable for aging industrial facilities. Many existing plants face challenges when expanding safety systems due to limited infrastructure capacity, shutdown restrictions, or high installation costs. Wireless technologies provide a practical pathway for modernization while minimizing operational disruption.
In oil and gas production, refining, and chemical processing environments, safety requirements continue to evolve as operators manage increasingly complex assets. Technologies such as wireless gas monitoring help companies improve compliance, enhance operational awareness, and support more proactive approaches to process safety management.
The latest Rosemount 928 enhancement highlights Emerson’s continued focus on developing flexible instrumentation solutions that address real-world industrial challenges. By combining wireless connectivity with advanced gas detection capabilities, the technology provides operators with a scalable option for expanding safety coverage across demanding environments.
As industrial facilities continue moving toward digital transformation, wireless measurement and monitoring technologies are expected to become an increasingly important part of modern safety strategies. Emerson’s expanded gas detection platform represents another step toward more connected, responsive, and intelligent industrial operations.
