UV-01.1.ex
Ultraviolet flame detector
The UV-01.ex ultraviolet flame detector with pressure-tight encapsulated
metal housing detects fires with open flame as well as arcs in potentially explosive areas. It responds to the UV-C radiation mainly contained in the flame borders, in the range from 185 to 235 nm, and is very well suited for open flames without smoke development.
The sensor does not respond to sunlight, light bulbs, fluorescent lights or
flying sparks. False tripping is possible, however, with UV radiating light sources. Included in this are, for example, halogen and mercury vapor lamps, lightning, arc during welding work and reflections of the above radiation sources. In addition, smoke, dust and water vapor, as well as contamination of the UV pane, absorb the ultraviolet radiation and therefore negatively effect the response behavior of the sensor.
