4.4.5
IONISATION RADIATION
The FV300 detector, like other infrared detectors, is insensitive to X-rays and gamma radiation as
used in non-destructive testing.
The detector will operate normally and will not false alarm when exposed to this type of radiation.
However, long-term exposure to high radiation levels may lead to permanent damage.
4.4.6
CORROSION
The use of a sealed stainless steel 316L enclosure allows the FV300 detector to withstand the
effects of most corrosive substances and gas. In particular, it meets the requirements for sulphur
dioxide (SO
2
) conditioning in EN 54-10 and exposure to salt mist concentration as specified in
LRS, DNV and GL test specifications for approval of equipment for marine use.
Note:
Over time, the outer surfaces of the detector may discolour and give an
appearance of being ‘rusty’. This discolouration is caused by the oxidation of
contaminants collected on the surface of the enclosure, especially areas with a
textured finish. It only affects the surface of the material and does not reduce the
thickness or affect the mechanical properties of the enclosure in any way.
