60-2780-1 Fireye Scanner

Overview

The Fireye 60-2780-1 is a replacement electronics assembly for the Phoenix Series 2 85UVF1-1CEX integrated ultraviolet (UV) flame scanner. As a critical component of industrial burner management systems, this microprocessor-based device uses a solid-state sensor to detect UV radiation in the 185 to 260 nm range. It is designed to be housed in an explosion-proof (CEX) enclosure for use in ATEX-rated hazardous environments. By integrating signal processing and an internal flame relay, it eliminates the need for external amplifiers, providing a definitive flame-on or flame-off signal to ensure safe combustion.

Features

• High-sensitivity solid-state UV sensor for accurate flame detection.
• Internal flame relay with automatically set ON/OFF thresholds for simplified system design.
• Microprocessor-based signal processing that monitors flame flicker frequency.
• Full self-diagnostics and electronic self-checking for fail-safe operation.
• Integrated 4-20mA analog output for monitoring flame strength.
• Automatic sensor gain selection during setup for optimized performance.
• Rugged design compatible with ATEX/IECEx explosion-proof housings.

Applications

The 60-2780-1 is primarily used in utility and industrial boilers, process heaters, and refinery furnaces. It is specifically engineered to monitor flames from gaseous fuels like natural gas and propane, as well as light oil fuels. Its explosion-proof compatibility makes it a standard choice for hydrocarbon processing plants, chemical facilities, and power generation plants where burners are located in classified hazardous areas. It is also suitable for use on duct burners and incinerators in industrial combustion systems.
