FIREYE 95UVS2E-1 | Ultraviolet (UV) Flame Scanner

Product Overview

The FIREYE 95UVS2E-1 is a state-of-the-art ultraviolet (UV) flame scanner, engineered to deliver precise and reliable flame detection in industrial combustion environments. As a key component in FIREYE’s flame monitoring portfolio, this scanner specializes in detecting the ultraviolet emissions unique to flames, making it highly effective for applications where infrared (IR) detection may be less suitable—such as flames from hydrogen, methane, or other fuels with low CO₂ emissions. The 95UVS2E-1 works seamlessly with flame amplifiers like the FIREYE 25SU3-2000 to form a comprehensive safety system, ensuring rapid response to flame anomalies in boilers, furnaces, and industrial heaters.

With advanced UV sensing technology, the 95UVS2E-1 distinguishes between genuine flames and false sources (e.g., sunlight, arc welding), minimizing false alarms. It is widely deployed in industries such as oil and gas, chemical processing, and power generation, where accurate flame detection is critical for preventing accidents and optimizing combustion efficiency. The 95UVS2E-1 stands out for its rugged design, extended operational range, and compatibility with FIREYE’s ecosystem of control components.

Key Features and Benefits

Specialized UV Sensing

The FIREYE 95UVS2E-1 utilizes a UV sensor tuned to the 185-260 nm wavelength range, which is emitted by most hydrocarbon and non-hydrocarbon flames but rarely by ambient light sources. This specialization ensures exceptional accuracy in detecting flames from fuels like hydrogen, natural gas, and propane—fuels that may not produce strong IR signatures. By focusing on UV emissions, the scanner avoids false triggers from hot surfaces or infrared radiation, making it ideal for environments where IR-based detectors struggle.

Extended Environmental Durability

Built to excel in harsh conditions, the 95UVS2E-1 features an IP67-rated enclosure, offering superior protection compared to standard industrial scanners. This rating ensures resistance to dust, water immersion (up to 1 meter), and corrosive agents—critical for outdoor installations, coastal facilities, or waste incinerators. Its operating temperature range of -40°C to 90°C further enhances versatility, allowing reliable performance in extreme cold or high-heat environments such as metal smelting furnaces.

Wide Voltage Compatibility

The 95UVS2E-1 accepts 12-24 VDC input, providing flexibility during installation. This wide-range compatibility simplifies integration into diverse electrical systems, from older 12 VDC setups to modern 24 VDC configurations, eliminating the need for additional voltage converters. This feature reduces installation time and potential failure points, ensuring seamless integration with existing control panels.

Rapid Response Time

With a response time of less than 150 milliseconds, the 95UVS2E-1 ensures near-instantaneous detection of flame presence or loss. This speed is critical for safety, as it allows amplifiers like the 25SU3-2000 to trigger immediate actions—such as shutting off fuel supplies or activating alarms—minimizing the risk of unburned fuel accumulation. In dynamic processes like batch heating, this rapid response also enables precise adjustments to fuel-air mixtures, optimizing efficiency.

Seamless System Integration

The 95UVS2E-1 is designed to work harmoniously with FIREYE’s amplifiers, controllers, and accessories. Its 0-10 mV AC output signal integrates seamlessly with the 25SU3-2000 flame safeguard amplifier, enabling advanced signal processing and safety relay activation. It also pairs with inner carrier assemblies like the 61-7443-3 for secure mounting in flues, ensuring optimal positioning for flame detection. This interoperability simplifies system upgrades, allowing facilities to enhance safety without replacing entire control infrastructures.
