Compact, Lightweight, Low Current Consumption, Low Cost

Operates as High Sensitivity UV Sensor with UV TRON

Suitable for Flame Detectors and Fire Alarms

Hamamatsu C3704 series UV TRON driving circuits are low current consuming, signal processing circuits for the UV TRON, well known as a high sensitivity ultraviolet detecting tube. The C3704 series can be operated as a UV sensor by connecting the UV TRON and applying DC low voltage, as they have both a highvoltage power supply and a signal processing circuit on the same printed circuit board.

Since background discharges of the UV TRON caused by natural excitation lights (such as a cosmic ray, scattered sunlight, etc.) can be cancelled in the signal processing circuit, the output signals from the C3704 series can be used without errors.

When the high sensitivity sensor “UV TRON R2868” (sold separately) is used, the flame from a cigarette lighter (flame length: 25mm) can be detected even from a distance of more than 5m.

APPLICATIONS

● Flame detectors for gas and oil lighters

● Fire alarms

● Combustion monitors for burners

● Electric spark detector

● UV photoelectric counter
