Technical index:
Overview The flame detector is equipped with a high-sensitivity ultraviolet sensor to monitor early flame ultraviolet radiation. The unique ultraviolet flame sensor can respond to ultraviolet radiation at the moment of fire and explosive ignition. The unique circuit design makes it used in various environments and technical requirements. Special logic circuits help prevent false alarms caused by solar radiation. The UV flame detector is especially suitable for detecting invisible flames: hydrogen, silane, ammonia, hydride and metal fires. Accurate flame detection suitable for industrial environments can work in the most demanding environments such as high / low temperature, high humidity, and vibration.
