The IS IR3 Flame Detector is designed for harsh environments in either indoor or outdoor applications. It is sensitive to low frequnency flickering IR radiation emitted from flames during combustion. The sensor operates even through a layer of oil, dust, water vapour or ice. These detectors have been approved by  Baseefa to standards EN50014, EN50020 and EN50284. The requirements of Directive 94/9/EC, the Atmosphere Explosives ATEX directive have also been met.
