85IRF1-1CEX Fireye Cenelec Explosion Proof Housing

Overview

The Fireye 85IRF1-1CEX is a high-performance Phoenix Series 2 integrated infrared (IR) flame scanner designed for industrial combustion monitoring. This microprocessor-based device features a solid-state infrared sensor and an internal flame relay, which eliminates the need for a remote flame amplifier. It is housed in a heavy-duty Cenelec/ATEX certified explosion-proof aluminum enclosure, making it suitable for hazardous environments where safety and reliability are paramount. The scanner detects the amplitude of flame modulations (flicker) and automatically determines optimal ON/OFF thresholds during its setup procedure.

Features

• Integrated Design: Combines flame sensing, amplification, and a flame relay into a single, compact unit.
• Advanced Sensing: Utilizes solid-state infrared (IR) sensors to detect emissions in the 830 to 1100 nanometer wavelength range.
• Self-Checking: Incorporates continuous electronic self-checking and full self-diagnostics for maximum safety.
• Automatic Setup: Features an automatic setup routine that stores target flame amplitudes and selects appropriate sensor gain and thresholds.
• Hazardous Area Protection: Cenelec EExd IIC T6 and ATEX/IECEx explosion-proof housing for use in volatile industrial zones.
• Analog Output: Provides a standard 4-20mA output signal proportional to flame strength for remote monitoring.
• Onboard Interface: Includes a pushbutton keypad and LED indicators for local status and setup.

Applications

The 85IRF1-1CEX is ideal for a wide range of industrial and commercial burner management applications, particularly those requiring continuous operation in hazardous locations. Typical applications include duct burners, industrial oil and gas burners, refinery furnaces, low NOx burners, waste gas units, and incinerators. It is especially well-suited for monitoring flames from fuels that produce strong infrared signatures, such as oil, heavy oil, and various gases, and is often used in power generation and petrochemical facilities.
