Brand of fiber optic temperature sensor
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, thermistors, 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.
Fiber optic temperature sensors and measurement technology are important development directions in the power electrical industry. Due to its small size, хөнгөн жин, flexibility, good electrical insulation, flexible bending, зэврэлтэнд тэсвэртэй, large measurement range, and high sensitivity, 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, explosion-proof, 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 (such as intensity, долгионы урт, frequency, үе шат, polarization state, гэх мэт.), 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, precision, 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, мөн хөнгөн жинтэй; Insulation, water resistance, high temperature resistance, зэврэлтэнд тэсвэртэй, гэх мэт. 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.

The advantage of fiber optic sensors is that compared with traditional sensors, fiber optic sensors use light as the carrier of sensitive information and fiber optic as the medium for transmitting sensitive information. They have the characteristics of fiber optic and optical measurement, and have a series of unique advantages. Good electrical insulation performance, strong resistance to electromagnetic interference, non invasiveness, high sensitivity, easy to achieve remote monitoring of the measured signal, зэврэлтэнд тэсвэртэй, explosion-proof, flexible optical path, and easy to connect with computers.

Fiber optic sensors can be used for measuring physical quantities such as displacement, vibration, rotation, pressure, bending, strain, velocity, acceleration, current, magnetic field, voltage, чийгшил, temperature, sound field, flow rate, concentration, pH value, and strain. The application range of fiber optic sensors is very wide, involving almost all important fields in the national economy and defense, as well as people’s daily lives. 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, such as bridges, dams, 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.
In the power system, 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. Distributed fiber optic temperature sensors are a high-tech technology developed in recent years for real-time measurement of spatial temperature field distribution. Distributed fiber optic temperature sensing systems 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 degree, making them very suitable for large-scale intersection temperature measurement applications.
Үүнээс гадна, 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, long-distance transmission, and the ability to achieve multi parameter, distributed, 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.
