v 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 maintaining false alarm immunity. It
detects in the ultraviolet (UV) spectral range for
optimized speed of response.
It is fast and capable to detecting the ultraviolet (UV) rays
emitted by a burning substance and is used in high hazard
applications 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 33cmX33cm,
Height 5cm.
