Crowcon SharpEye 40/40 UV/IR Flame Detector Series
Spectrex offers two versions of the new
40/40 Series UV/IR Flame Detectors:
Model 40/40L (& LB) provides a combination
of UV and IR sensors, where the IR sensor
operates at a wavelength of 2.5-3.0 ìm, and
can detect hydrocarbon-based fuel and gas
fires, hydroxyl and hydrogen fires, as well as
metal and inorganic fires.
Model 40/40L4 (& L4B) is identical to the
40/40L except that the IR sensor works at a
wavelength of 4.5 ìm and is only suitable
for hydrocarbon-based fires.
The UV/IR flame detector senses radiant energy
in the short wave section of both the ultraviolet
and infrared portions of the electromagnetic
spectrum. The signals from both sensors are
analyzed for frequency, intensity and duration.
Simultaneous detection of radiant energy
in both the UV and IR sensors triggers
an alarm signal.
The UV sensor incorporates a special logic
circuit that helps prevent false alarms caused
by solar radiation.
Due to increased reliability, the 40/40 Series
warranty period has been extended to 5 years
and is SIL2 (TUV) approved to IEC 61508.
