Flame detector (also known as photosensitive fire detector)It is a fire detector that detects the intensity of light and the frequency of flame flicker during flame combustion. Among numerous fire safety equipment, flame detectors play a crucial role as they can quickly and accurately detect the occurrence of fires, buying valuable time for personnel evacuation and firefighting operations.

Flame detectors typically operate in extremely harsh environments such as high temperatures, open flames, dust, etc. Once a fire occurs, the temperature at the scene will rise sharply, and the window of a detector made of ordinary glass material may rapidly deform and melt at such high temperatures, leading to the failure of the detector.

Advantages of Sapphire Window Plates


1. Excellent high temperature resistance performance
Sapphire window panels, with their excellent high-temperature resistance, can maintain stable physical and chemical properties in high-temperature flames. its Extremely high melting point Ensure that reliable protective barriers can still be provided for the optical components inside the detector in high-temperature environments during a fire, enabling them to function properly and continuously monitor flame signals.
2. Excellent optical performance
In addition to high temperature resistance, sapphire window panels also have excellent optical performance. it Has extremely high transmittance for light of specific wavelengths This is crucial for flame detectors to accurately capture the specific wavelength of light signals emitted by flames. Both ultraviolet and infrared rays can pass through the sapphire window to the maximum extent possible, be accurately received by the photosensitive components inside the detector, and then converted into electrical signals to trigger the alarm system. Compared to other materials, the high transparency of sapphire window plates makes the response speed and detection accuracy of flame detectors faster, greatly reducing the probability of false positives and false negatives.


In practical applications, sapphire window panels have demonstrated significant advantages in flame detection systems in many large venues.For example, in areas with high fire risks such as large warehouses and chemical parks, installing flame detectors equipped with sapphire window panels enables the system to quickly and accurately respond to fires.
