UV7SC Fireye UV Scanner

Overview

The Fireye UV7SC is a high-performance, self-checking ultraviolet (UV) flame scanner designed for continuous monitoring of gas and oil flames in industrial burner management systems. It features an integrated mechanical shutter that periodically blocks the sensor’s view to verify the integrity of the scanner’s internal circuitry, ensuring maximum safety by preventing “runaway” scanner conditions where a false flame signal might be generated.

Features

• Self-check mechanism with a mechanical shutter that closes every 10 seconds to verify circuit integrity.
• High-quality fused silica quartz lens for superior UV sensitivity and durability.
• Machined 6061 aluminum alloy housing with seals for protection in demanding environments.
• Push-pull electro-magnetically driven photo shutter for long service life.
• Easy maintenance design allows for replacement without disturbing existing wiring.
• Solar blind spectral sensitivity (180 to 230 nanometers) to prevent interference from ambient light.

Applications

The UV7SC is specifically engineered for industrial and commercial applications requiring continuous flame monitoring, such as boilers and process burners. It is compatible with Fireye MB-Series (Multi-Burner), SB-Series (Single-Burner) controls, and flame sensing modules including the MBPF-100S and MB-600PF. It is ideally suited for monitoring flames from gaseous fuels and light oils where verified safety and regulatory compliance are critical.
