◆Measurement Principle
The product utilizes ultraviolet light (narrow spectrum wavelength: 185~260nm) to detect the presence of flames. The sensing element employs the photoelectric effect of metals and gas multiplication effect forultraviolet detection, being insensitive to visible light while capable of rapidly responding to ultraviolet radiation emitted during fire and explosion ignition. However, ultraviolet radiation sources such as lightning, arc welding,mercury lamps, halogen lamps, radiation sources, UV sensors, and direct sunlight radiation may trigger the sensor. The detector display can show the detector status, and its automatic testing function ensures the detector operates properly at all times.◆Main Features▶The host and sensors are installed separately;▶Optional: Industrial explosion-proof model;▶The sensor is made of stainless steel;▶The sensor observation window employs quartz glass specifically designed for dedicatedwavelength transmission;▶The sensor light guide tube can be removed to accommodate a wider-angle observationsource;▶Full Chinese LCD display with backlight;▶The sensor is separated from the output wiring chamber;▶The host can be wall-mounted or pipeline-installed.◆Application ScenariosSuitable for flame detection in industrial settings, can be used as flame-out alarm and combustion alarm.
