45UV5-1101EX Fireye HOUSING & Scanner

Overview

The Fireye 45UV5-1101EX is a self-checking ultraviolet (UV) flame scanner integrated into an explosion-proof housing, designed for high-risk industrial environments. This system is engineered to detect UV radiation emitted by fossil fuel flames while providing continuous diagnostic monitoring through an internal electromagnetic shutter. The assembly is specifically rated for hazardous locations where flammable gases or dust may be present, ensuring fail-safe flame supervision for critical combustion systems.

Features

• Self-checking mechanism with an internal shutter that periodically blocks the sensor to verify proper electronic and sensor operation.
• Explosion-proof housing certified for NEMA 7, Class 1, Div 1 & 2 (Groups C & D) and Class 2, Div 1 & 2 (Groups E, F, & G).
• High-sensitivity quartz lens and UV-eye detector for precise flame sensing.
• Robust die-cast aluminum construction with oil-resistant gaskets for durability in harsh industrial conditions.
• Integrated power transformer and electronic components within a sealed enclosure.
• Hinged mount design to facilitate easy access for lens cleaning and maintenance.
