UVTRON® are UV ON/OFF detectors that can quickly detect a flame’s weak UV emission from a distance, making them suitable for flame detectors and fire alarms. They have a narrow spectral sensitivity from 185 nm to 300 nm and are completely insensitive to visible light. They make it possible to design a high-sensitivity, quick-response UV detection system with simple circuitry.
Ensuring safety when producing, transporting, storing and utilizing hydrogen requires reliable monitoring and detection of hydrogen flames. However, hydrogen flames are nearly invisible and conventional methods that rely on infrared sensors and flame rods are not sensitive enough to detect the faint hydrogen flames. This problem has led to a surge in demand for high-performance sensors specifically optimized for monitoring and detecting hydrogen flames.

Hamamatsu offers UVTRON UV sensors that are highly sensitive to the weak UV light emitted from hydrogen flames and ensure speedy and accurate flame detection.
UVTRON accurately detects weak UV light emitted from hydrogen flames. It easily detects, for example, flames from hydrogen burner about 10 m away. This long-distance detection allows greater flexibility in UVTRON installation locations.
UVTRON has no spectral response to UV through visible light from sunlight. This eliminates the need for having optical filters to cut out extraneous light. UVTRON is usable both indoors and outdoors.
UVTRON quickly senses UV light and outputs a signal within a few ms so can detect a hydrogen flame as soon as it ignites. UVTRON also instantaneously detects a hydrogen flame that fizzles out, which has been nearly impossible to do until now with indirect detection and other methods utilizing thermal sensing. UVTRON in this way delivers a quick response ensuring a high level of safety management.
