FLAME SENSOR
UVtron
®
UVtron is an ultraviolet detector tube that uses the photo-
electric effect of metal and gas multiplication effect of electric
current by means of discharge. It has a very narrow range of
sensitivity from 185 nm to 300 nm and is completely insensi-
tive to visible light. Because it used the discharge phenom-
enon, its sensitive is high and an adequate output voltage is
obtained, making it possible to design a high-sensitivity,
quick response ultraviolet detection with simple circuitry.
The UVtron reliably detects faint ultraviolet emissions from
flames, making it ideal for applications such as fire alarms,
arson surveillance, and burner combustion monitor devices.
The UVtron can also detect discharges such as corona dis-
charges from high-voltage power transmission lines.
