The Flame sensors/UV TRON from Hamamatsu is capable of detecting faint ultraviolet emissions brought about by fire. It is useful for warning against dangers through arson surveillance, burner combustion monitor devices and fire alarms. This sensor tube is engineered to use the photoelectric result of gas and metal multiplication current electric effect through discharging.
Designed with a 185 nm to 300 nm sensitivity range, it has easy wiring due to its use of discharge phenomenon. Its non-responsiveness to regular light makes it more accurate for emission detection.
It also identifies dischargers from the corona through high-voltage elctrical lines.
