Sensitivity results have all been obtained
by testing theEV-UV with the following
flame size as below:-
The EV-UV sensor may be positioned in two ways. Each way determines the distance and area coverage
of a single detector.
Fig. 3. shows the EV-UV in the B-D position, and Fig. 4. shows the EV-UV in the C-A position. In both
examples, the shaded area indicates the actual detection area achieved for each positioning of
the sensor. The examples are based on tests carried out using a fuel fire covering an area of
approximately 33 square centimetres. (See Fig. 5.)
Fig. 6. demonstrates how the area of coverage of
the EV-UV sensor increases the further away
from the sensor head you go. The sensor
has a maximum detection angle of 100 degrees.
