65UV5-1004QD Fireye Integrated Flame Scanner

Overview

The Fireye 65UV5-1004QD is a self-checking, microprocessor-based ultraviolet (UV) flame scanner designed for industrial burner management and flame safeguard applications. This integrated, one-piece system detects UV emissions from fossil fuel flames, such as natural gas, propane, and light oil. By incorporating an internal flame relay with a fixed ON/OFF threshold, it eliminates the need for an external flame amplifier, providing a compact and reliable solution for modern combustion systems.

Features

• Self-Checking Technology: Utilizes an electro-mechanical shutter mechanism to provide continuous self-checking of the UV tube, ensuring high levels of safety and reliability.
• Integrated Design: Features an internal SPDT flame relay, allowing for direct connection to burner management systems without additional signal processing hardware.
• Analog Feedback: Provides a 4-20 mA DC analog output proportional to the flame signal strength for remote monitoring and trend analysis.
• Local Diagnostics: Includes a two-color internal LED (visible through a rear viewing port) that indicates flame status and fault conditions.
• Durable Construction: Housed in a rugged cast aluminum NEMA 4X / IP66 enclosure, making it suitable for harsh industrial environments and hazardous locations.
• Ease of Maintenance: Equipped with an 8-pin quick-disconnect connector to simplify field wiring, installation, and replacement.
