Ion Fire Sensor
The device is made based on
the flame conductivity effect and is used to detect the flame condition 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. The size of the
signal is related to factors such as the intensity of the flame. The more
intense the flame, the larger the signal.
