Contrive UV4 SH Manual

UV4 is an high performance selected UV detector that can be
SH
used for flame detection in gas, oil and mixed burners together
with suitable Burner Control Unit or Flame Amplifier Device.
The core component is a glass bulb filled with gas, containing
two electrodes. When appropriate voltage is applied between
electrodes, if an ultraviolet electromagnetic radiation hits the
phototube, electrons emitted by negative biased electrode can
be captured by positive biased electrode, starting an ionization
process leading an electric discharge between electrodes
producing a current flow.
UV4 is a compact unit for industrial use, the body is made by
SH
thermal isolating material to avoid sensor overheating when
applied on the burner head.
When the temperature at peepsight exceed 70°C it's advisable
to add a ¾" pipe spacer (up to 40 cm) between the burner and
the sensor and apply a cooling filtered air flow to the special
connection provided on the side of the probe.
Although UV4SH is blind to sunlight, some discharge lamps
produces UV emission that can be detected by the phototube.
