The sensor probe is a rare earth fluorescent substance that excites fluorescence after being irradiated with fixed wavelength light. After the excitation stops, the relationship between the decay time constant of fluorescence afterglow and temperature is a quasi exponential function. The temperature can be obtained by measuring the time constant of afterglow.

蛍光光ファイバー温度センサー are one of the hot research topics in the field of modern fiber optic sensing technology. Many temperature measurement scenarios have special conditions, which may cause some practical difficulties in temperature measurement. In all research activities seeking alternative methods for temperature sensors, fluorescent fiber optic temperature sensors are increasingly being valued for their advantages such as anti electromagnetic interference, 小型, 低い伝送損失, 耐食性. Temperature is a fundamental physical quantity that represents the degree of coolness or heat of an object. All processes in nature are closely related to temperature, and it is one of the most important lateral parameters in temperature measurement science and industrial process control. With the improvement of industrial automation and the expansion of continuous production scale, the demand for temperature measurement is becoming increasingly large. Many environments cannot use traditional electronic temperature sensors due to high temperature, 高電圧, and high electromagnetic interference, and alternative methods need to be adopted.

光ファイバー温度センサー have become an effective candidate solution, with advantages such as resistance to electromagnetic interference, 高温, 腐食, and miniaturization. They have a wide range of application prospects in industrial production, with low fiber optic transmission loss, making them very convenient for both on-site use and long-distance transmission. さらに, the fiber optic has a small diameter, simple structural arrangement, and small volume. したがって, as a 光ファイバー温度センサー, it is suitable for almost all detection objects and can be used in special situations where other temperature sensors are difficult to apply, such as sealing, 高電圧, strong magnetic field, nuclear radiation, strict explosion-proof, waterproof, very small spaces or very small workpieces.

The biggest advantage of the fluorescent powder afterglow temperature measurement method compared to other 光ファイバー temperature measurement principles is that temperature measurement is independent of light intensity. It has strong compatibility with the inconsistency of fluorescence intensity, optical path attenuation, and circuit drift in hardware. The system mainly conducts real-time online monitoring of abnormal temperature changes in the busbar and contacts. このシステムでは, users can monitor temperature changes in key areas in real time on the local upper computer, and issue real-time alarm reports (warnings, アラーム, and exceeding limits) based on temperature changes. 同時に, with the help of powerful upper computer functions, it is possible to analyze the temperature change cycle, view real-time and historical curves, predict changes in alarm situations, and achieve data storage for multiple devices.

The requirements for environment and accuracy require innovation in temperature measurement technology! Research and development have posed new challenges, and the requirements for temperature in fields such as industrial research and development, biomedical research, 等. are constantly expanding. 例えば, explosive high voltage and strong electromagnetic fields with corrosive gas liquids, as well as the demand for rapid response, are challenging in these fields. The environment in which the measured object is located is quite harsh, either in motion or in an extremely difficult position to approach, or there is strong electromagnetic interference around the measured object, as well as the thermal therapy side temperature in medicine, which makes temperature measurement difficult.
