Flame sensor (UV TRON)



The UVTRON ultraviolet ON/OFF detector that makes use of the photoelectric effect of metal and the gas multiplication effect. It has a narrow spectral sensitivity of 185 nm to 280 nm, being completely insensitive to visible light. Unlike semiconductor detectors, it dose not require optical visible-cut filters, thus making it easy to use.
