FAQ

Question: Can Saacke FLS09 UV-5L detect all types of combustion flame?

The Saacke FLS09 UV-5L cannot detect all types of flames. This flame detector adopts a dual channel sensor design, with one channel being a UV flame sensor and the other an infrared sensor working in a specific flame radiation center frequency band.

It is mainly suitable for detecting flames with obvious ultraviolet or infrared radiation characteristics.

• For flames with strong ultraviolet radiation, such as metal flames (e.g., magnesium and aluminum fires), the UV sensor can play a better role.
• At the same time, the infrared sensor can detect flames with specific infrared radiation characteristics. However, for some smoldering flames or flames with very weak ultraviolet and infrared radiation, such as some slow burning solid material flames under special circumstances, or flames occurring in environments with strong light interference, its detection effect may be affected, and it may even fail to detect them.
• In addition, if the flame is blocked by obstacles, and the ultraviolet or infrared rays cannot reach the detector, it will also lead to the failure of normal detection.

Question: How accurate is the Saacke FLS09 UV-5L in detecting flames?

The Saacke FLS09 UV-5L has relatively high accuracy in flame and fire detection, which is mainly reflected in the following aspects:

• Dual – channel Sensor Design: It adopts a dual channel sensor design, with one channel being a UV flame sensor that is insensitive to sunlight and the other being an infrared sensor operating in a specific flame radiation center frequency band. The dual sensor dual detection mode can effectively distinguish the flame from other light sources, reducing the false alarm rate and improving the accuracy of detection. For example, in an industrial environment with strong ambient light, the UV sensor is not easily affected by sunlight, and the infrared sensor can accurately identify the infrared radiation characteristics of the flame, so as to achieve accurate detection of the flame
• Digital Flame Evaluation Technology: The detector uses digital flame evaluation technology, which can analyze the flame status more accurately. It can monitor the light intensity, flicker frequency and other characteristics of the flame in real time, and make a more accurate judgment on the presence of the flame according to the set algorithm, with high safety and strong reliability
• Applicability to Various Fuels: It is suitable for all single burner or multi burner devices, and applicable to the variable type adjustment of all fuels. This means that it can accurately detect the flames generated by different fuels, because it can adapt to the different light radiation characteristics of different fuels through corresponding adjustments, ensuring the accuracy of detection in a variety of working conditions
• High protection Performance and Stable Operation: With an IP65 protection rating, it can work stably in harsh environments, effectively preventing dust and water ingress, avoiding the influence of environmental factors on the detection accuracy, and ensuring the long term stable and accurate operation of the detector.
