Flame Detection: It is mainly used to detect the infrared radiation of flames. It has a fast response to the specific wavelength of 4.45 μm in the flame spectrum, which can effectively identify the presence of flames and is widely used in fire - fighting equipment and safety monitoring systems.
Industrial Automation: In industrial production processes, it can be used to monitor the combustion state of furnaces or detect the presence of flames in some high - temperature processes to ensure the normal progress of production and the safety of equipment.
Environmental Monitoring: It can be used to detect wildfires or monitor the combustion of some harmful substances in the environment to provide data support for environmental protection and disaster prevention.
Characteristics:
High Sensitivity: It has a high - sensitivity photosensitive element, which can detect very weak light signals, enabling it to quickly respond to the weak infrared radiation of flames, even in low - light or complex backgrounds.
Fast Response: With a typical rise time of 20 ms and a maximum of 30 ms, it can quickly detect the sudden appearance of flames and convert the optical signal into an electrical signal for rapid transmission and processing, which is crucial for timely fire alarm and safety protection.
Narrow - Band Spectral Response: The spectral response is centered at 4.45 μm, which has strong selectivity for the infrared wavelength of the flame. It can effectively avoid interference from other wavelengths of light, improve the accuracy of flame detection, and reduce false alarms.
Good Stability: It has good stability in a certain temperature range (- 20 °C - 50 °C) and humidity range (15% - 90% RH), with a small temperature coefficient of element resistance. It can work stably for a long time and is less affected by environmental factors, ensuring the reliability of detection results.
Compact Structure: Housed in a TO - 18 metal package, it has a small volume and is easy to install and integrate into various detection systems, which is convenient for use in different application scenarios such as fire - fighting equipment and industrial detection.
