UVTRON®is an ultraviolet ON / OFF sensor tube that uses the photoelectric effect of metal and gas multiplication effect of electric current by means of discharge. It has a very nar- row range of sensitivity from 185 nm to 300 nm and is com- pletely insensitive to visible light. Because it used the dis- charge phenomenon, its sensitive is high and an adequate output voltage is obtained, making it possible to design a high-sensitivity, quick response ultraviolet detection with sim- ple 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 discharges from high-voltage power transmission lines.
