85UVF1-1QD Fireye Flame Scanner

Overview

The Fireye 85UVF1-1QD is a high-performance, microprocessor-based Phoenix Series 2 integrated ultraviolet (UV) flame scanner. Designed for industrial combustion applications, it provides accurate and reliable flame detection by monitoring the ultraviolet radiation emitted by the burner. This integrated scanner includes an internal flame relay with automatically set ON/OFF thresholds, eliminating the need for a remote flame amplifier or separate flame switch. The unit utilizes solid-state UV sensors and advanced flicker-detection technology to distinguish between target flames and background radiation, ensuring high levels of safety and operational integrity.

Features

• Integrated design featuring an internal flame relay and solid-state UV sensor.
• Microprocessor-based technology with electronic self-checking and full self-diagnostics.
• Selectable Flame Failure Response Time (FFRT) for customized system safety.
• Quick Disconnect (QD) 8-pin electrical connector for simplified installation and maintenance.
• Automatically stores flame amplitude characteristics and selects optimal sensor gain during setup.
• Internal flame relay (SPST N.O.) and fault relay (SPST N.C.) outputs.
• Analog 4-20mA output for real-time monitoring of flame signal strength.
• Robust construction with a cast aluminum housing rated for IP66/NEMA 4X environments.
