Product Description

Fireye UV7A4 flame detector

Fireye UV7A4 is an ultraviolet flame detector designed for industrial combustion environments, achieving precise monitoring by capturing specific ultraviolet radiation (185-260nm) emitted by flames. As an important model in Fireye's UV series, its core advantage lies in strong anti-interference capability, which can effectively filter non-flame light sources such as sunlight and electric arcs to avoid false triggering. Powered by 24V DC and housed in a NEMA 4X enclosure, it operates stably in harsh industrial environments, widely used in gas and oil combustion systems to provide reliable flame status monitoring and safety protection for boilers, kilns and other equipment.

Function Offering

1. Accurate Flame Identification:Only responds to 185-260nm ultraviolet band, specifically designed for flame radiation, effectively eliminating interference from non-flame light sources with extremely low false alarm rate
 2. Fast Response Capability:≤3-second detection response time, which can quickly trigger an alarm when the flame is extinguished or abnormal, providing sufficient time for emergency shutdown of the combustion system
 3. Harsh Environment Adaptation:NEMA 4X enclosure resists rain, dust and corrosive gases; -40+71℃ wide temperature range adapts to extreme industrial environments
 4. Reliable Output Control:SPDT relay output can directly link with combustion controllers to achieve automatic shutdown protection in case of flame faults, without additional conversion components
 5. Easy Installation & Debugging:1/2" NPT standard port for quick installation, supporting multi-angle adjustment of detection direction to adapt to flame positions of different burners
