Brand of 광섬유 온도 센서

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, 서미스터, 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.

광섬유 온도 센서s and measurement technology are important development directions in the power electrical industry. Due to its small size, 가벼운 무게, 유연성, 좋은 전기 절연성, flexible bending, 내식성, large measurement range, 그리고 높은 감도, 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, 폭발 방지, 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 (강도와 같은, 파장, 빈도, 단계, 편광 상태, 등.), becoming the modulated signal source. After being sent through the fiber optic to the photodetector and demodulated, 측정된 매개변수를 얻습니다..

The application scope of fiber optic sensors

The characteristics of fiber optic sensors are sensitivity, 정도, strong adaptability, compactness, 그리고 지능. Fiber optic has many unique characteristics compared to other sensors, such as resistance to electromagnetic and atomic radiation interference, fine diameter, soft texture, and light weight; 격리, water resistance, 고온 저항, 내식성, 등. 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.

Especially, they can be used safely and effectively in harsh environments, solving many technical problems that have existed in industries for many years, and have great market demand. Mainly manifested in the following applications:

The application of interferometric gyroscopes and grating pressure sensors in urban construction, 교량과 같은, 댐, 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.

전력 시스템에서는, 온도, 전류 등의 매개변수를 측정해야 합니다., such as temperature detection in the stator and rotor of high-voltage transformers and large motors. 전기 센서는 전자기 간섭에 취약하기 때문에, they cannot be used in such situations and can only be used with fiber optic sensors. 분산 광섬유 temperature sensors are a high-tech technology developed in recent years for real-time measurement of spatial temperature field distribution. 분산 광섬유 온도 감지 시스템 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. 이 기능으로, we can continuously measure the temperature at various points within a few kilometers along the fiber optic line in real time, 최대 미터의 위치 정확도와 최대 측정 정확도 1 도, making them very suitable for large-scale intersection temperature measurement applications.

게다가, fiber optic sensors can also be applied in railway monitoring, rocket propulsion systems, and oil well detection.

Fiber optic has significant advantages in broadband, large capacity, 장거리 전송, and the ability to achieve multi parameter, 분산, and low-energy sensing. Fiber optic sensing can continuously absorb new technologies and devices from fiber optic communication, and various fiber optic sensors are expected to be widely applied in the Internet of Things.
