The sensor probe is a rare earth fluorescent substance that excites fluorescence after being irradiated with fixed wavelength light. Após a excitação parar, 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.

Sensores de temperatura de fibra óptica fluorescentes 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, tamanho pequeno, baixa perda de transmissão, e resistência à corrosão. 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, alta tensão, and high electromagnetic interference, and alternative methods need to be adopted.

Sensores de temperatura de fibra óptica have become an effective candidate solution, with advantages such as resistance to electromagnetic interference, alta temperatura, corrosão, 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. Além disso, the fiber optic has a small diameter, simple structural arrangement, e pequeno volume. Portanto, as a sensor de temperatura de fibra óptica, 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, alta tensão, campo magnético forte, radiação nuclear, estrito à prova de explosão, impermeável, very small spaces or very small workpieces.

The biggest advantage of the fluorescent powder afterglow temperature measurement method compared to other fibra óptica 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. Com este sistema, users can monitor temperature changes in key areas in real time on the local upper computer, e emitir relatórios de alarme em tempo real (avisos, alarmes, e ultrapassando limites) com base nas mudanças de temperatura. Ao mesmo tempo, com a ajuda de poderosas funções superiores do computador, é possível analisar o ciclo de mudança de temperatura, visualizar curvas históricas e em tempo real, prever mudanças em situações de alarme, e obter armazenamento de dados para vários dispositivos.

O fluorescence temperature sensor system consists of a fluorescence fiber optic sensing probe, an IF-C2B16F20 transmissor de temperatura de fibra óptica, an IF-YS10F liquid crystal display instrument (configurado de acordo com os requisitos), um sistema de medição de temperatura de fibra óptica de fluorescência background monitoring computer, e um software de monitoramento de fundo de fibra óptica fluorescente.

O sistema de medição de temperatura de fibra óptica de fluorescência utilizes the principle of optical characteristic changes caused by temperature changes of fluorescent powder for temperature measurement, que tem segurança extremamente alta, resistência de alta pressão, resistência à corrosão, resistência à interferência eletromagnética, e precisão de medição de alta temperatura. Comunicação RS485 (Protocolo Modbus RTU) pode ser usado entre o transmissor de temperatura de fibra óptica e o computador de monitoramento. Due to the temperature range! 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, etc.. are constantly expanding. Por exemplo, 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.
