QISNUN's newly listed UL94 Flame Chamber is highly recommended to customers who have high requirements for high automation and accurate test data.


What points should be paid attention to when using UL94 Flame Chamber?


1. There may be conflicts between flame static parameters and flame dynamic parameters. In the actual operation, the thermal control personnel have already calibrated during the overhaul, but there will still be problems during the ignition process. The ignition is very strong, but the fire detection does flash, which causes a lot of problems during operation. The heat control part will also add a lot of trouble. Because the frequency of the flame is not uniform when it is burning, it is a random function and is affected by many factors

2. The contradiction between the small viewing angle of the UL94 Flame Chamber and the large erratic flame. The probe of the UL94 Flame Chamber is generally between 10 degrees and 15 degrees. This viewing angle is a bit small, so it may not be able to aim at the erratic flame under different conditions at any time. But in order to accurately detect the flame, the detection head of the UL94 Flame Chamber must be aimed at the area of the burning flame, but in most cases, the UL94 Flame Chamber changes at any time with the angle of the burner.


3. There is a contradiction between the installation and adjustment of the UL94 Flame Chamber probe. The viewing angle of the flame detector probe cannot be adjusted from the outside. This requires changing the viewing angle of the probe to improve the accuracy of UL94 Flame Chamber detection.
