Key Features
- Detects hydrocarbon and invisible hydrogen flames
- Dual infrared sensors for flame and false-source discrimination
- Sensitive to 1–15 Hz flickering IR radiation for early detection
- Operates even with lens contamination from dust, oil or moisture
- Selectable relay or 4–20 mA outputs for system flexibility
Overview
The Talentum IR2 Flame Detector is designed to protect areas where open fires may occur. It detects almost all flame types, from hydrocarbon fires with 4.3 μm emissions to invisible flames such as hydrogen. Using two infrared sensors that respond to different wavelengths, the detector accurately distinguishes genuine flames from false sources such as sunlight or hot surfaces.
It is sensitive to the low-frequency flicker of infrared radiation between 1 and 15 Hz, allowing detection even when the lens is partially obscured by oil, dust, water, vapour or ice. Advanced filtering and signal processing ensure high immunity to false alarms.
The IR2 provides selectable output options, offering either relay contacts or a 4–20 mA signal for flexible system integration. Rugged and reliable, it delivers dependable flame detection in industrial or high-risk environments where early fire warning is essential.
