20/20L-LB
UV/IR Flame Detector
The SharpEye UV/IR Optical
Flame Detectors 20/20L and
20/20LB (which includes a
BIT function) are an
improved version of the
well-proven Spectrex Ultra
Violet/Infra Red (UV/IR)
optical flame detectors featuring
modern microprocessors and detection algorithms
that provide excellent detection sensitivity combined
with enhanced immunity to false alarms.
These enhanced models were developed in light
of our highly successful experience in high-speed
flame detection technology for both military and
commercial industrial applications.
Both models are designed to detect hydrocarbonbased fuel fires, hydroxy and hydrogen fires as well
as metal and inorganic fires.
The UV/IR flame detector senses energy in the short
wave section of both the ultraviolet and infrared
portions of the electromagnetic spectrum.
The sensor band pass has been carefully selected
to ensure the greatest degree of spectral matching
to the radiant energy emissions of fire, and the
lowest degree of matching to non-fire stimuli.
The UV sensor incorporates a special logic circuit
that helps prevent false alarms caused by solar
radiation.
The IR sensor is sensitive to radiation over the range
of 2.5 to 3.0 microns. The signals from both sensors
are analyzed for frequency, intensity and duration.
Simultaneous matching of radiant energy in both
the UV and IR sensors triggers an alarm signal.
