PHOTOCELLS
FLAME SENSORS FOR FUEL OIL
BURNERS

Introduction
Flame detection in fuel oil burners occurs by means of
sensors detecting the presence of flame through an electrical
signal, which can be used by ignition and control devices.
Generally, to detect the presence of flame in these
appliances a photocell is used, which exploits the light
generated by the flame itself.
Description
These are the most used flame sensors for fuel oil burners.
Photocells vary their ohmic resistance according to the light
incidence; this property is exploited to detect the occurred
flame generation in burners.
Various types of photocells are available, differing from each
other in their application and casing. Fig.1 shows the FC7,
FC8 and FC9 photocells; the difference between FC7 and
FC8 models consists in the detecting element, which lights up
laterally in the FC7 and frontally in the FC8. The FC9
photocell is suitable to be light up laterally; an inbuilt diode
enables this photocell to be used with particular devices (for
example Brahma 32C, 32CN, GS2, GP2. ). Fig.2 shows the
FC11, FC13 and FC14 photocells, differing from each other
only in the fixing system, as both of them light up laterally and
frontally. Fig.3 shows FC14 and FC14L photocells, differing
from each other in the case length, even if both of them are
able to be light up laterally and frontally. They are provided
with a connection plug which facilitates assembly and
maintenance operations. The standard length of the photocell
connecting cable is 600mm; the operating temperature range
ensuring the longest life of flame sensors (approximately
50,000 hours) is comprised between -10°C and +60°C.
