4-wire UV Flame detector with relay output

General Description 

The device is an ultraviolet-only flame detector designed to detect fires and provide alarm outputs directly from the detector while maintaing false alarm immunity. It detects in the ultraviolet spectral range for optimized speed of response. It is fast and capable to detecting the ultraviolet rays emitted by a buming substance and is used in high hazard appplications such as petrochemical plants,munitions factories and other areas where flammable or explosive liquids or solids are handled or stored.

The flame sensor adopts an ultraviolet photosensitive tube, with qualities of highly sensitive,reliable,dust-resistant,corrosion proof and moisture-resistant,therefore is not sensitive in sunlight,dust,oil,tolerance of fume,and humidity.Set in a standard calibration to detect a flames at a distance of 25 meters,which flame created by 2kg ethanol in a container of base 33x33cm,height 5cm.
