What are the differences in accuracy of different types of flame detectors when detecting flames?
Some flame detectors are particularly sensitive to specific wavelengths of light, so they are particularly accurate in detecting certain types of flames.
Some flame detectors perform well in dealing with flame detection in complex environments, eliminating interference and making accurate judgments.
Others may have an advantage in detecting faint flames, as they can capture those small flames that are difficult to detect in a timely manner.
Of course, different types of flame detectors have their own characteristics and applicable scenarios.
So when choosing, it is important to carefully select based on actual needs.
