85UVF1A-1QDK3 Fireye Scanner

Overview

The Fireye 85UVF1A-1QDK3 is a high-performance Phoenix Series 2 integrated flame scanner designed for industrial and commercial burner management systems. This microprocessor-based device utilizes a solid-state ultraviolet (UV) sensor to monitor flame flicker modulations across a wide frequency spectrum. As an integrated unit, it incorporates an internal flame relay, eliminating the need for a remote flame amplifier or flame switch, which simplifies cabinet wiring and reduces potential failure points. This specific model features an advanced K3 optical filter that extends its spectral sensitivity up to 500nm, making it highly effective for specialized combustion environments.

Features

• Self-checking ultraviolet flame sensing technology for continuous and reliable flame supervision.
• Integrated design with an internal flame relay and automatically set ON/OFF thresholds.
• Advanced K3 optical filter extending spectral sensitivity from the standard 310 nm range up to 500 nm.
• Selectable Flame Failure Response Time (FFRT) settings for customized application flexibility.
• Internal flame relay with automatically set ON/OFF thresholds, removing the need for external amplifiers.
• Full self-diagnostics and electronic self-checking for enhanced safety and performance verification.
• Analog 4-20mA output of flame strength provided as standard for real-time monitoring.
