Hamamatsu UVTRON R9454 Flame sensors water cannon open flame detector

Hamamatsu UVTRON R9454 Flame sensors water cannon open flame detector

R9454 is a 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 260 nm, being completely insensitive to visible light. Unlike semiconductor detectors, it dose not require optical visible-cut filters, thus making it easy to use.

FLAME SENSOR UV TRON R9454 Quick Dete ction of Flame from Distance, Compact U V Sensor with High Sensitivity and Wide Directivity, Suitable for Flame Detect ors and Fire Alarms.
