Sense-WARE knows what safety means.
It means that when the distance from the detector
to the fire
is doubled the fires needs to be four times larger. E.g.
detects a 0,09 m2 (1 sqft) petrol fire
at 15 meters
(45 ft). In order to see the fire at 30 meters (90 ft) the size of the fire
needs to be at least 0,36 m2 (4 sqft).
is a substance or vapour
blinds the flame sensor
E.g., a UV detector
be blinded by oil
on the lens, Hydrocarbon vapours
, Chloride based vapours
An IR detector
blinded by fog, water and ice or a salt layer on the lens (salt takes up water).
A multi IR flame detector
can be blinded or masked by black-body radiation
from hot machinery
or direct sunlight
The user looses faith and maybe a real
is discarded out of disbelieve. A UV
detector false alarms
to the radiation of Arc Welding
or high pressure mercury lamps
(without the protective
en static arcs
. An IR
may false alarm to chopped black body radiation
in some cases direct chopped sunlight
are less susceptible to black body radiation
but may get insensitive.
