95IRS2-1CEX Fireye Scanner

Overview

The Fireye 95IRS2-1CEX InSight I is a microprocessor-based integrated infrared flame scanner designed for industrial burner management. As an “Expanded Model S2,” it features advanced detection capabilities, including the AutoTune function for automatic programming and remote communication support. This specific “CEX” variant is housed in an EExd IIC T6 explosion-proof enclosure, making it suitable for hazardous environments, and is CE approved for use in international markets.

Features

• Infrared (IR) sensor technology optimized for detecting flame flicker in coal and oil applications.
• Integrated design with an internal flame relay, eliminating the need for a separate remote flame amplifier.
• AutoTune capability allows for automatic selection of the best modulation frequency and sensor gain with manual override.
• Electronic self-checking system ensures continuous safety without the need for a mechanical shutter.
• User interface featuring an eight-character alpha-numeric LED display and a four-button keypad for local configuration.
• Remote communication support via RS485 interface for monitoring and setup through a PC.

Applications

The 95IRS2-1CEX is primarily used in large industrial and commercial combustion systems, including multi-burner boilers, furnaces, and kilns. Its infrared sensor makes it particularly effective for monitoring flames produced by coal and heavy oil. The explosion-proof housing allows for installation in refinery, petrochemical, and hazardous waste gas applications where ATEX or EExd certification is required.
