Flame sensor module

C16956-02

A module that integrates the UVTRON® flame and discharge sensor with a driver circuit and a signal processing circuit for background noise processing and other tasks.

It can be used to easily detect UV light simply by inputting DC voltage. The module acquires information such as sensitivity (detection count number) and a UV light detection signal via a D-sub connector, and can perform UVTRON® operation checks using the built-in UV-LED. The light-receiving unit is fitted with a G1 screw thread so that it can be easily installed on combustion devices.
