FIREYE 85UVF1A-1QDK3 Ultraviolet (UV) flame detector
The FIREYE 85UVF1A-1QDK3 is a microprocessor-based ultraviolet (UV) flame scanner from the Phoenix Series II, designed for industrial burner management systems. It integrates a high-sensitivity UV sensor (295–340 nm), internal flame relay, and self-diagnostics into a rugged IP66 housing, delivering reliable flame detection without external amplifiers. The unit features an 8-pin quick-disconnect (QD) connector, a K3 filter, and selectable Flame Failure Response Time (FFRT), making it ideal for hazardous industrial environments.
Key Functions
- UV Flame Detection: Senses 295–340 nm UV emissions from fossil fuel flames (natural gas, propane, diesel, etc.), ignoring false sources like hot refractory or sunlight.
- Internal Flame Relay: Automatically sets ON/OFF thresholds during setup, eliminating the need for remote flame amplifiers or switches.
- Self-Diagnostics & Self-Checking: Continuous electronic self-verification ensures scanner integrity; auto-selects sensor gain for optimal performance.
- Analog Output: Provides 4–20 mA proportional signal for flame strength monitoring and integration with control systems.
- Hazardous Area Compliance: FM, UL/c, CE approved for Class I Division 2 hazardous areas (with 59-546-xx cable).
