Rosemount 965 flame detector for hazardous areas

Emerson has announced a flameproof model for the Rosemount 965 Flame Detector, adding hazardous-location certification for applications where hydrocarbon flame detection is required. The flameproof model combines QuadSense technology, factory-calibrated-for-life operation, broad integration options and rugged enclosure protection to support fire protection strategies matched to application needs.

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 45 m 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 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 hydrocarbon flame detection is needed.
