What is the key feature of a flame detector?

A flame detector is designed to identify the presence of flames, and its key feature is its ability to detect electromagnetic light waves produced by flames. Different flames emit specific wavelengths of light, often within the infrared or ultraviolet spectrum. When the flame detector senses these light waves, it confirms the presence of a flame and can trigger an alarm or alert necessary personnel for action.

This mechanism of detection is crucial for fire safety systems, as it allows for rapid identification of fire incidents, which is essential for minimizing damage and ensuring safety. The use of light waves specifically tailored to the characteristics of flames makes the flame detector more effective and reliable in distinguishing between actual flames and other heat sources.
