New flameproof model adds hazardous area certification to the Rosemount 965 Flame Detector with QuadSense technology and factory calibrated for life operation

Emerson has expanded its industrial flame detection portfolio with the launch of a new flameproof version of the Rosemount™ 965 Flame Detector, providing hazardous area certification for applications that demand reliable hydrocarbon flame detection in some of the world's most challenging operating environments.

The latest addition to the Rosemount 965 range has been developed to support a wider variety of industrial fire protection applications across the oil and gas, chemical, petrochemical and process manufacturing sectors. By combining hazardous location certification with Emerson's proven QuadSense™ infrared detection technology, factory calibrated for life operation and extensive system integration capabilities, the new detector offers greater flexibility for engineers designing and maintaining industrial fire and gas detection systems.

The new flameproof model enables organisations to deploy the Rosemount 965 in hazardous environments while maintaining a practical balance between fast flame detection, reduced maintenance requirements and installation flexibility. This allows operators to enhance fire protection strategies without introducing unnecessary complexity or increasing routine servicing demands.

QuadSense technology delivers reliable hydrocarbon flame detection

At the heart of the Rosemount 965 Flame Detector is Emerson's QuadSense technology, which uses four independent infrared sensors to accurately distinguish genuine hydrocarbon flames from non-flame background radiation. This advanced detection capability helps minimise nuisance alarms while maintaining dependable fire detection performance in demanding industrial environments.

Under specified operating conditions, the detector is capable of identifying hydrocarbon fires at distances of up to 45 metres (150 feet), with response times typically achieved in less than five seconds. Five selectable sensitivity levels also allow users to optimise detector performance according to the specific risks and environmental conditions of each application.

This combination of rapid response and intelligent discrimination makes the Rosemount 965 well suited to facilities where dependable fire detection is critical for protecting personnel, assets and operational continuity.

Factory calibrated for life to reduce maintenance

One of the key benefits of the Rosemount 965 Flame Detector is its factory calibrated for life design, helping reduce the need for recurring calibration activities throughout the product's operational life. This can significantly reduce routine maintenance workloads while improving system availability.

The detector also incorporates infrared built-in test functionality that continuously verifies the integrity of both the optical components and internal electronics. By providing continuous self-monitoring between scheduled manual inspections, operators can have greater confidence in detector performance while reducing unnecessary maintenance interventions.

Flexible integration for industrial fire and gas systems

The Rosemount 965 has been engineered for straightforward integration into existing industrial safety and automation infrastructure.

Multiple output options, including HART® connectivity, enable compatibility with widely used industrial communication systems and plant control architectures. Universal wiring further simplifies specification, installation and commissioning across multiple sites, helping organisations standardise flame detection equipment throughout their facilities.

The detector is also protected by robust IP66 and IP68 enclosure ratings, ensuring reliable operation in harsh industrial environments where exposure to dust, water and challenging weather conditions is common.

Suitable for hazardous and non-hazardous industrial applications

The introduction of the flameproof model significantly broadens the deployment opportunities for the Rosemount 965 Flame Detector.

Typical hazardous area applications include:

Oil and gas production and processing facilities
Chemical manufacturing plants
Petrochemical processing sites
Storage tank farms
Hazardous materials storage facilities
Explosives and munitions sites

In addition to hazardous environments, the Rosemount 965 also supports a wide range of non-hazardous and light industrial applications where dependable hydrocarbon flame detection remains essential. These include transportation infrastructure, public buildings, cable tunnels, semiconductor manufacturing facilities, warehouses and many other industrial locations.

The expanded product range allows engineers and safety professionals to select the most appropriate certification and enclosure option while maintaining consistent detection technology across different facility types.

“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.”
