Flame detectors are devices designed to identify the presence of fire by sensing the light emitted from flames. They are commonly used in various settings, including industrial facilities, commercial buildings, and aircraft, to enhance safety and prevent fire-related disasters. These detectors can respond to different wavelengths of light, such as ultraviolet (UV) or infrared (IR), depending on the type of flame they are designed to detect. When a flame is detected, the device triggers an alarm or activates fire suppression systems, allowing for a quick response to potential hazards. Flame detectors are essential components of fire protection systems and are often integrated with other safety equipment, such as smoke detectors and sprinkler systems, to provide comprehensive fire safety solutions.
