UV1A-1-CEX Fireye Cenelec Explosion Proof Housing

Overview

The Fireye UV1A-1-CEX is a specialized ultraviolet (UV) flame scanner assembly featuring a miniature UV1A scanner integrated into a CENELEC-certified EExd IIC explosion-proof housing. It is designed for high-safety industrial environments where the presence of explosive gases or vapors requires ruggedized, flameproof equipment. This non-self-checking scanner is optimized for monitoring flames from fuel gases and No. 2 fuel oil in industrial burner management and flame safeguard systems.

Features

• Explosion-Proof Protection: Housed in a CENELEC EExd IIC rated enclosure, making it suitable for hazardous locations.
• Ultraviolet Sensing Technology: Utilizes a quartz UV tube to accurately detect radiation emitted by gas and light oil flames.
• Compact Miniature Scanner: Incorporates the UV1A series internal components, known for their small footprint and reliability.
• Non-Self-Checking Design: Ideal for intermittent burner operations where the system cycles at least once every 24 hours.
• Durable Construction: Features a non-replaceable UV tube sealed within a rugged housing for long-term industrial use.

Specifications

• Scanner Model: UV1A-1-CEX
• Housing Certification: CENELEC EExd IIC (Explosion-proof)
• Detection Type: Ultraviolet (UV)
• Mounting: 1 inch NPT mounting thread
• Conduit Entry: 1/2 inch NPT cable entry

Applications

The UV1A-1-CEX is used in hazardous area industrial combustion applications, particularly where explosion-proof equipment is mandated by safety codes. It is compatible with Fireye flame safeguard controls, including the M-Series, M-Series II, MicroM, FlameWorx, MB-2, and D-Series, as well as BurnerLogix and Nexus systems. It is primarily applied to monitor flames from natural gas, propane, and No. 2 oil in refineries, chemical plants, and other volatile industrial environments.
