FLAME SENSOR
UVtron
A
Even at these current values, the electrodes are not consumed immediately, but the service life is noticeably reduced. Use the tube within the recommended
current values.
B
This is the maximum momentary current that can be handled if its full width at half maximum is less than 10
μ
s.
C
These are representative values for a wavelength of 200 nm and a light input of 10 pW/cm
2
. Think of these values as relative sensitivity values. In actual use,
the sensitivity will vary with the wavelength of the ultraviolet radiation and the drive circuitry employed.
D
Measured under room illuminations (approximately 500 lux) and recommended operating conditions. Note that these values will increase somewhat in
outdoor uses due to the effect of sunlight.
E
This is the service life under the recommend operating conditions. Since high ambient temperatures will reduce the service life, when using the tube in a
high-temperature application, such as a burner monitor, consider using air-cooling.
F
When configuring the tube with an external quenching circuit, use circuit constants so that the quenching time becomes longer than these values listed.
When using a pulse driven circuit using CR, if the applied voltage is in the recommended range, the quenching time tq can be calculated with the following
formula. (Refer to the diagram of the recommended operating circuit.)
