Ion fire sensor

Ion fire sensor

A device based on the flame conductivity effect is used to detect flame conditions in the environment. It is a fire-resistant metal tube mounted on an insulator. Generally, a DC positive potential is applied to the metal tube and a DC negative potential is applied to the aircraft body. When there is a flame between the metal tube and the aircraft body , the fire area is ionized and has the ability to conduct electricity, forming an electrical path between the metal tube and the aircraft body and outputting a signal.
