R2868 is a UV TRON ultraviolet detector that makes
use of the photoelectric effect of metal
and the gas multiplication
effect. It has a narrow spectral
sensitivity of 185 to 260 nm, being
completely insensitive to visible light.
Unlike semiconductor
detectors, it does not require optical
visible-cut filters, thus
making it easy to use.
In spite of its small size, the R2868 has
wide angular sensitivity
(directivity) and can reliably and
quickly detect weak ultraviolet
radiations emitted from flame due to use
of the metal plate
cathode (eg.
it can detect the flame of a cigarette lighter at a
distance of more than 5 m.).
The R2868 is well suited for use in flame
detectors and fire
alarms, and also in detection of
invisible discharge phenomena
such as corona discharge of high-voltage
transmission lines.
