Overview

The Fireye UV1A50-EX is an explosion-proof ultraviolet (UV) flame scanner designed for use in hazardous locations. This unit consists of a UV1A50 miniature non-self-checking scanner mounted within a rugged NEMA 7 rated housing. It is engineered to detect ultraviolet radiation from fuel gas and light oil flames while providing superior protection in environments where combustible gases or dusts may be present.

Features

• Explosion-proof housing rated for NEMA 7, Class 1, Div 1 and 2 (Groups C and D), and Class 2, Div 1 and 2 (Groups E, F, and G).
• Miniature non-self-checking UV tube technology for accurate flame detection.
• Integrated 50-foot armored cable for secure electrical connections in industrial environments.
• Designed for intermittent operation where the burner cycles at least once every 24 hours.
• Rugged construction suitable for indoor and outdoor applications in petrochemical, refinery, and power generation facilities.
