Fireye 95UVS2-1 UV Scanner for Gas, Oil, and Dual-Fuel Burners

Technical Specifications

Main Features and Advantages

Superior flame discrimination and stability: The Fireye 95UVS2-1​ utilizes a high-sensitivity UV sensor tube that is selectively sensitive to the ultraviolet radiation characteristic of hydrocarbon flames, while being largely immune to interference from incandescent hot refractory, boiler tubes, or sunlight. This provides excellent discrimination between true flame radiation and background infrared/visible radiation, minimizing the risk of false flame signals. The scanner features automatic gain control and sophisticated signal processing algorithms that stabilize the flame signal despite fluctuations in flame intensity, ensuring a reliable “flame on” signal during normal modulated operation and preventing nuisance shutdowns.Enhanced diagnostics and connectivity (Model Insight): This is the defining advantage of the 95UVS2-1. Unlike conventional scanners, it provides continuous, real-time diagnostic data. Key parameters such as UV signal strength, gain setting, and a “viewability” index (which infers lens contamination) are available. This allows maintenance teams to proactively clean the scanner lens or troubleshoot issues beforea failure causes a burner trip. This data can be accessed locally via a handheld configurator or communicated digitally to a remote DCS or building management system via protocols like Modbus, enabling centralized monitoring of an entire fleet of burners. Furthermore, the Fireye 95UVS2-1​ is designed for exceptional durability, with a rugged, air-purged housing that protects the optical components from heat, dust, and corrosive environments, ensuring long service life and reliable protection.

Application Field

The Fireye 95UVS2-1 Model Insight Enhanced UV Flame Scanner​ is deployed across a vast spectrum of industries where safe and reliable combustion is non-negotiable. Its primary application is in boiler plants of all sizes, from large utility and industrial power generation boilers to smaller commercial and institutional heating boilers. Here, the Fireye 95UVS2-1​ is responsible for monitoring the flame on gas, oil, or dual-fuel burners, providing the essential permissive for fuel valve operation and triggering immediate safety shutdowns (FSD) upon flame failure. In process heating, it is critical for fired heaters and furnaces in oil refineries, petrochemical plants, and chemical processing facilities, where it safeguards reactors and cracking furnaces that operate at extreme temperatures.Beyond traditional boilers and heaters, the Fireye 95UVS2-1​ is also essential in environmental control equipment. It is used in thermal oxidizers and incinerators that destroy volatile organic compounds (VOCs) or waste gases, where continuous flame supervision is required to ensure complete combustion and regulatory compliance. Similarly, it finds application in cement kilns and other mineral processing direct-fired systems. Any application involving an automated, fuel-fired burner that requires compliance with safety standards like NFPA 85, NFPA 86, or FM Global Data Sheets will benefit from the reliable flame supervision and advanced diagnostic capabilities of the Fireye 95UVS2-1​ scanner, making it a global standard for industrial burner safety.
