In many fields where temperature measurement is required, traditional temperature measurement techniques often use thermocouples, thermistors, optical pyrometers, semiconductors, and temperature sensors from other fields. Electronic signals are used as the sensing medium, that is, the modulation effect of temperature on electronic signals is used to convert temperature changes into voltage signal changes, and temperature measurement is carried out based on the magnitude of the voltage signal.
Although traditional temperature measurement techniques have been widely used, they are greatly limited in special working conditions and environments, such as explosive, запалим, high voltage, strong electromagnetic fields, corrosive gases and liquids, as well as environments that require rapid response and non-contact. Especially in strong electromagnetic interference environments, the transmission of electrical signals will be severely disrupted, leading to a decrease in temperature measurement accuracy.

Fluorescence fiber optic temperature measurement Технология

In the existing field of fiber optic sensing technology, fluorescent fiber optic temperature sensors have the advantages of intrinsic safety, immunity to electromagnetic interference, Съпротивление на високо напрежение, and corrosion resistance. They can work in strong electromagnetic interference and harsh chemical environments, and have become the best means of accurate and reliable temperature measurement in industries such as semiconductors, власт, microwave energy, petroleum, and medicine. Normally, a fluorescent fiber optic temperature sensor consists of an optical fiber with a temperature sensing fluorescent material probe and a temperature transmitter. The probe part is a fluorescent fiber optic temperature sensing probe independently developed by FJINNO, which is not affected by external electromagnetic noise, resistant to high voltage and corrosion, and can work in strong electromagnetic interference and harsh chemical environments. The geometric dimensions of the optical probe and fluorescent material used can be very small, corresponding to a small heat capacity and high measurement responsiveness, which is conducive to miniaturization and integration. Fiber optic temperature sensors are easy to use, accurate in measurement, and have extremely high commercial value.

The fluorescence fiber optic temperature measurement system achieves fiber optic temperature measurement by setting up a fiber optic probe installed in contact with the measured object, a transmitter connected to the fiber optic probe through the fiber optic cable, a data processing module connected to the transmitter, and a fiber optic adapter module connected to the data processing module. By using fiber optic probes as temperature sensors, the anti-interference performance is improved, and even in strong electromagnetic interference environments, the temperature value of the measured object can be accurately measured; By installing the fiber optic probe in contact with the object being measured, the temperature sensing efficiency of the fiber optic probe has been improved, thereby enhancing the temperature measurement accuracy; By setting up a fiber optic adapter module, fiber optic communication between the temperature measurement device and the upper computer monitoring system has been achieved, improving the anti-interference performance of signal transmission.

Fiber optic temperature measurement technology is highly suitable for applications in high-voltage electromagnetic fields, such as transformer winding temperature, switchgear contact temperature, and high-voltage cable joint temperature, due to its material advantages. Понастоящем, the widely used fiber optic temperature sensors in the market include fluorescent fiber optic temperature sensors, fiber optic grating temperature sensors, and distributed fiber optic temperature sensors. Among them, the on-site calibration of grating and distributed temperature sensors is relatively complex, and they are mostly used for long-distance cable temperature online monitoring. The fluorescence fiber optic temperature sensor based on the principle of fluorescence attenuation duration has high measurement accuracy in the medium and low temperature range, and is easy and reliable to apply. Следователно, it is widely used in point temperature measurement applications such as transformer windings and switchgear contacts. Due to the fact that the core component of fluorescent fiber optic temperature sensors is the temperature probe, and the current manufacturing process of temperature probes is relatively complex, there are few domestic fiber optic temperature measurement manufacturers with high research and development levels. FJINNO is one of the few manufacturers that independently develops fluorescent fiber optic temperature measurement systems.

The preparation process of fluorescent temperature sensing fiber probes has good product consistency and a wide range of engineering applications. Fluorescent fiber temperature sensors have higher cost-effectiveness in industrial applications compared to other temperature sensing methods, thus better promoting and popularizing the application of fiber temperature sensing technology.
