العلامة التجارية ل مستشعر درجة حرارة الألياف الضوئية
A true brand ranking may not necessarily fully introduce so many domestic enterprises. Some well-known domestic brands of fiber optic temperature sensors include FJINNO, while other companies in the top 10 are not introduced.
Fiber optic sensors are sensors developed based on optical signals. The traditional temperature measurement method is based on signals such as thermocouples, الثرمستورات, and pyroelectric detectors. The development of temperature sensors has been many years, and fiber optic sensors can be widely used in situations with strong electromagnetic interference or flammable and explosive materials. Traditional temperature sensors based on other temperature measurement methods will be greatly limited.
مستشعر درجة حرارة الألياف الضوئيةs and measurement technology are important development directions in the power electrical industry. Due to its small size, خفيفة الوزن, المرونة, عزل كهربائي جيد, flexible bending, مقاومة التآكل, large measurement range, وحساسية عالية, optical fibers can serve as a reminder and expand the range of use in other temperature sensors, achieving products and methods that traditional temperature sensors cannot measure temperature.
In addition to its unique applications in temperature measurement, fiber optic sensing technology also has the characteristics of fast response, wide frequency band, مقاومة للانفجار, flameproof, and electromagnetic interference resistance compared to traditional temperature measurement instruments.
The basic working principle of fiber optic sensors is to send the light signal from the light source through the fiber optic into the modulator, causing the measured parameters to interact with the light entering the modulation region, resulting in changes in the optical properties of the light (مثل الشدة, الطول الموجي, تكرار, مرحلة, حالة الاستقطاب, إلخ.), becoming the modulated signal source. After being sent through the fiber optic to the photodetector and demodulated, the measured parameters are obtained.
The application scope of fiber optic sensors
The characteristics of fiber optic sensors are sensitivity, دقة, strong adaptability, compactness, and intelligence. Fiber optic has many unique characteristics compared to other sensors, such as resistance to electromagnetic and atomic radiation interference, fine diameter, soft texture, وخفيفة الوزن; العزل, water resistance, مقاومة درجات الحرارة العالية, مقاومة التآكل, إلخ. It can be used in areas that are inaccessible to humans (such as high temperature areas) or areas that are harmful to humans (such as nuclear radiation areas), and can also transcend human physiological boundaries to receive external information that human senses cannot perceive.

Mainly manifested in the following applications:
The application of interferometric gyroscopes and grating pressure sensors in urban construction, such as bridges, السدود, and oil fields. Fiber optic sensors can be embedded in concrete, carbon fiber reinforced plastics, and various composite materials to test stress relaxation, construction stress, and dynamic load stress, in order to evaluate the structural performance of bridges during short-term construction and long-term operation.
في نظام الطاقة, it is necessary to measure parameters such as temperature and current, such as temperature detection in the stator and rotor of high-voltage transformers and large motors. Due to the susceptibility of electrical sensors to electromagnetic interference, they cannot be used in such situations and can only be used with fiber optic sensors. الألياف الضوئية الموزعة temperature sensors are a high-tech technology developed in recent years for real-time measurement of spatial temperature field distribution. أنظمة استشعار درجة حرارة الألياف الضوئية الموزعة not only have the advantages of universal fiber optic sensors, but also have the sensing ability to distribute temperature at various points along the fiber optic line. With this feature, we can continuously measure the temperature at various points within a few kilometers along the fiber optic line in real time, with a positioning accuracy of up to meters and a measurement accuracy of up to 1 درجة, making them very suitable for large-scale intersection temperature measurement applications.
فضلاً عن ذلك, fiber optic sensors can also be applied in railway monitoring, rocket propulsion systems, and oil well detection.
Fiber optic has significant advantages in broadband, سعة كبيرة, long-distance transmission, and the ability to achieve multi parameter, موزعة, and low-energy sensing.
