What Is a Flame Scanner?
A flame scanner is an optical sensor designed for precise flame detection. It employs a series of components such as a lens to focus incoming light, a light sensor to detect this light, a filter to isolate specific wavelengths, along with signal processing circuitry, and a decision algorithm to accurately identify the presence of flames.
This technology stands out for its early detection capabilities, low rate of false alarms, ability to monitor large areas, and straightforward installation process. Flame scanners are available in various configurations, including standalone units, networked systems, and camera-based models, to suit diverse operational needs.
The operation of a flame scanner involves three primary steps: capturing light, analyzing the light for specific characteristics, and detecting flames based on light at certain wavelengths. This method allows for the reliable identification of fire hazards. Flame scanners are crucial for safety in a wide range of settings, including factories, warehouses, commercial spaces, hospitals, and residential areas. Factors to consider when choosing a flame scanner include its intended use, detection range, false alarm rate, and power requirements. Other important considerations are the installation environment, the necessity for regular inspections, and measures to minimize false alarms.
