product description

The OT-H-IR3-UV infrared flame detector contains three infrared sensors and optical filters. The main sensor has the highest sensitivity to the CO2 emission spectrum (4.4 μm) generated by the combustion of hydrocarbons, and the other three infrared sensor pairs Ambient light and background radiation interference from hot body radiation are used for detection. The detector has multiple signal processing algorithms, combined with logical comprehensive judgment of the flame flicker frequency, to maximize the suppression of false alarms and best fire detection performance.

The special fire signal processing method and multi-sensor detection technology greatly improve the sensitivity and response time of the detector.

The sensitivity of the detector can be adjusted automatically according to changes in the use environment. The detector is suitable for liquid and gas fires, open flames accompanied by smoke, and places where deflagration occurs.
