Compact, Lightweight, Low Current Consumption, Low Cost Operates as High Sensitivity UV Sensor with UVTRON Suitable for Flame Detectors and Fire Alarms.  The Flame detector is a Hamamatsu UV Tron 2868.

The UV TRON is an ultraviolet detector that makes use of the photoelectric effect of metal combined with the gas multiplication effect has a narrow spectral sensitivity of 185 to 260nm. Thus it is solar blind, being completely insensitive to visible light. Unlike semiconductor detectors, it does not require optical Visible-cut filters, thus making it easy to use.

UVTRON Flame detector is small, but has a wide angular sensitivity (directivity) and can reliably and quickly detect weak ultraviolet radiation emitted from a flame due to use of the metal plate cathode (e.g. it can detect the flame of a cigarette lighter at a distance of more than 5 m.). The Flame detector 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.  To minimize the area the sensor sees the flame, the field of view can be masked using one of our sensor shields.  These shields are useful if you are trying to locate the location of the flame.

The Hamamatsu C3704 Drive Circuit is an ideal choice for driving this detector.  Or you can select buy both in a package.
