60-2721-4 Fireye Scanner

Overview

The Fireye 60-2721-4 is a replacement scanner electronics assembly designed specifically for the InSight I 95UVS2E-1CEX series flame scanners. As a microprocessor-based integrated component, it utilizes a solid-state ultraviolet sensor to detect the presence or absence of a target flame. This specific “S2” expanded model features advanced digital signal processing and AutoTune capabilities to provide superior flame discrimination in complex, multi-burner environments. By integrating the detector and amplifier into a single unit, it eliminates the need for remote flame amplifiers and is designed for installation within hazardous area housings.

Features

• Solid-state ultraviolet (UV) sensor optimized for radiation detection between 295 and 320 nanometers.
• AutoTune function allows for automatic programming and optimization of scanner setpoints during installation.
• Integrated flame and fault relays enable standalone operation without a separate amplifier.
• Expanded Model S2 technology provides 21 choices of flame flicker frequency for enhanced discrimination between target and background flames.
• Electronic self-checking technology ensures continuous operational integrity without requiring a mechanical shutter.
• User interface includes an eight-character alpha-numeric LED display and a four-button keypad for local monitoring and configuration.
• Four selectable memory files for storing setpoints related to different fuels or firing rates.
• Remote communication capability for integration with PC-based monitoring software.

Applications

The 60-2721-4 electronics assembly is primarily used for the maintenance and repair of Fireye 95UVS2E-1CEX flame scanners. These scanners are ideal for gas-fired and light oil-fired industrial applications where UV sensing provides the most reliable detection. Typical installations include large multi-burner industrial boilers, process furnaces, and power generation units. It is specifically suited for complex combustion systems requiring high levels of discrimination to prevent false flame indications from adjacent burners.
