45UV5-1000CEX Fireye Cenelec Explosion Proof Housing

Overview

The Fireye 45UV5-1000CEX is a specialized flame scanning system designed for use in hazardous environments. This unit integrates a self-checking ultraviolet (UV) flame scanner within a Cenelec-approved explosion-proof housing. It is engineered to detect UV radiation emitted from fossil fuel flames while providing high levels of safety and reliability for industrial combustion systems. The assembly typically includes the 45UV5-1000 scanner, a 35-128 mounting flange, and the EExd IIC rated enclosure.

Features

• Self-Checking Technology: Features an internal electromagnetic shutter that periodically blocks the UV sensor to verify the proper operation of the scanner and signal circuits.
• Explosion-Proof Construction: Housed in a Cenelec EExd IIC rated enclosure, making it suitable for hazardous locations where explosive gases may be present.
• High Sensitivity: Utilizes a planoconvex quartz lens that can increase sensitivity to UV radiation by up to 400 percent compared to standard sensors.
• Selective Sensing: Specifically tuned to detect ultraviolet emissions (2200 to 2600 angstroms) and is blind to infrared radiation and visible light, reducing the risk of false signals from hot refractory.
• Rugged Design: The housing is constructed from cast aluminum with oil-resistant gaskets to withstand harsh industrial environments.

Applications

The 45UV5-1000CEX is primarily used for flame failure protection on single or multi-burner industrial applications, including electric utility boilers, large furnaces, and incinerators located in hazardous areas. It is designed to monitor flames from fossil fuels such as natural gas, propane, methane, butane, kerosene, and light diesel fuels. This scanner is compatible with Fireye Flame-Monitor, BurnerLogix, MicroM, and D-Series control systems. Note: For applications involving steam-atomized oil or pulverized coal, infrared scanners are generally recommended instead of UV.
