UV4 SH
HIGH PERFORMANCE UV FLAME DETECTOR
UV4SH is an high performance selected UV detector that can be
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.
UV4SH is a compact unit for industrial use, the body is made by
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.

SPECTRAL RESPONSE vs LIGHT SOURCES
UV4SH sensitivity is restricted to a very narrow region of ultraviolet rays, and exhibits no response at all in the visible
region. Gas and oil flames produces radiation that can be easily detected by UV4SH. The following diagram shows
spectral response of UV4SH and spectral emission for flames, sunlight and lamps.
SENSITIVITY vs SUPPLY VOLTAGE
The flame detector increase his sensitivity with higher operating voltages, the relationship is shown in the above
diagram. It's very important to keep the applied voltage within the recommended range to avoid malfunctions and
damages.
