A flame detector is a safety device designed to identify the presence of fire by detecting the light emitted from flames. These detectors are commonly used in industrial settings, such as oil refineries and chemical plants, where the risk of fire is high. They can respond quickly to flames, helping to prevent larger fires and protect both people and property. Flame detectors operate using various technologies, including infrared and ultraviolet sensors. When a flame is detected, the device triggers an alarm or activates fire suppression systems. This early detection is crucial for ensuring safety and minimizing damage in environments where flammable materials are present.
