QuadSense technology uses four infrared sensors to help distinguish hydrocarbon fires from non-flame background radiation, supporting reliable detection and resistance to nuisance alarms. Under specified conditions, the detector can detect hydrocarbon fires at distances up to 150 feet (45 meters) with response typically in less than five seconds. Five selectable sensitivity levels help users align performance with application needs.

The Rosemount 965 is factory calibrated for life, helping reduce recurring calibration routines. Infrared built-in test capabilities continuously verify optics and electronics integrity, supporting confidence between manual inspections. Multiple output options, including HART® connectivity, support integration with standard communication infrastructures, while universal wiring helps simplify specification and streamline sitewide deployment.  IP66 and IP68 enclosure protection supports performance in demanding operating environments.

The new flameproof model can be applied in environments often found in oil and gas facilities, chemical and petrochemical plants, storage tank farms, hazardous materials storage areas, and explosives or munitions sites. The Rosemount 965 also supports non-hazardous and light-industrial applications such as transportation infrastructure, public buildings, cable tunnels, semiconductor facilities, warehouses, and other sites where dependable hydrocarbon flame detection is needed.

“Customers need flame detection technology that aligns with the risk, environment and operational needs of each application,” said Evgeny Rivkin, flame and gas product manager with Emerson’s measurement instrumentation business. “This new flameproof model expands the Rosemount 965 offering for hazardous locations, helping teams balance detection performance, resistance to nuisance alarms and routine calibration requirements.”

The new flameproof model is available now.
