resistor within 2.5 cm
from the anode lead end of UV TRON.
UV TRON Driving Circuit C3704 series (Option)
Hamamatsu also provide the driving circuit
C3704 series for R2868 operation.
C3704 series include a high voltage power
supply and a signal processing circuit in
printed circuit board, which allows to
operate R2868 easily as a flame sensor
with the low input voltage (DC 6 to 30 V)
only.
For the details, please refer to the
datasheet of C3704 series.
PRECAUTIONS FOR USE
Ultraviolet Radiation
The UV TRON itself emits ultraviolet radiation in operation. When using two or more UV TRONs at the same time in close position, care should be
taken so that they do not optically interfere with each other.
Vibration and Shock
The UV TRON is designed in accordance with the standards of MIL-STD-202F (Method 204D/0.06 inch or 10g, 10- 500Hz, 15 minutes, 1 cycle) and
MIL-STD-202F (Method 213B/100g, 11ms, Half-sine, 3 times). However, should a strong shock be sustained by the UV TRON (e.g. if dropped), the
glass bulb may crack or the internal electrode may be deformed, resulting in deterioration of electrical characteristics. So extreme care should be
taken in handling the tube.
Polarity
Connect the UV TRON with correct polarity. Should it be connected with reverse polarity, operating errors may occur.
WARRANTY.
The UV TRON is covered by a warranty for a period of one year after delivery. The warranty is limited to replacement of any defective tube due to
defects traceable to the manufacturer.
