UV-01.1.ex
UV flame detector
The UV-01.1.ex ultraviolet flame detector with a pressure-tight metal housing detects both fires with open flames and electric arcs in potentially explosive areas.
It responds to the UV-C radiation in the range of 185-260 nm, which is mainly contained in the edges of the flames, and is very suitable for open flames without smoke development.
The detector does not respond to sunlight, incandescent lamps, fluorescent tubes and flying sparks.
However, false triggering is possible with light sources that emit UV radiation.
This includes, for example, halogen and mercury vapor lamps, lightning, arcs during welding work and the reflections from these radiation sources.
In addition, smoke, dust and water vapor as well as dirt on the UV pane absorb the ultraviolet radiation and impair the detector’s response.
