Fluorescent powder temperature measurement, fluorescence afterglow temperature measurement, kipimo cha joto cha maisha ya fluorescence, fluorescence fiber temperature measurement. 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.

Sensorer za joto za nyuzi za fluorescent 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, ukubwa mdogo, hasara ya chini ya maambukizi, na upinzani wa kutu. 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, voltage ya juu, and high electromagnetic interference, and alternative methods need to be adopted.

Sensorer za joto za fiber optic have become an effective candidate solution, with advantages such as resistance to electromagnetic interference, joto la juu, kutu, na 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. Aidha, the fiber optic has a small diameter, simple structural arrangement, and small volume. Kwa hiyo, as a sensor ya joto ya fiber optic, it is suitable for almost all detection objects and can be used in special situations where other temperature sensors are difficult to apply, kama vile kuziba, voltage ya juu, strong magnetic field, nuclear radiation, strict explosion-proof, isiyo na maji, very small spaces or very small workpieces.

The biggest advantage of the fluorescent powder afterglow temperature measurement method compared to other fiber ya macho 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. With this system, users can monitor temperature changes in key areas in real time on the local upper computer, na kutoa ripoti za kengele za wakati halisi (maonyo, kengele, na kuvuka mipaka) kulingana na mabadiliko ya joto. Wakati huo huo, kwa msaada wa kazi za juu za kompyuta zenye nguvu, inawezekana kuchambua mzunguko wa mabadiliko ya joto, tazama mikondo ya wakati halisi na ya kihistoria, kutabiri mabadiliko katika hali ya kengele, na kufikia hifadhi ya data kwa vifaa vingi.

The fluorescence temperature sensor system consists of a fluorescence fiber optic sensing probe, an IF-C2B16F20 kisambaza joto cha nyuzi macho, an IF-YS10F liquid crystal display instrument (configured according to requirements), a mfumo wa kipimo cha joto cha nyuzi za fluorescence background monitoring computer, and a fluorescence fiber optic background monitoring software.

The mfumo wa kipimo cha joto cha nyuzi za fluorescence utilizes the principle of optical characteristic changes caused by temperature changes of fluorescent powder for temperature measurement, which has extremely high safety, high pressure resistance, upinzani wa kutu, upinzani wa kuingiliwa kwa sumakuumeme, and high temperature measurement accuracy. Mawasiliano ya RS485 (Modbus RTU protocol) can be used between the fiber optic temperature transmitter and the monitoring computer. 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, nk. are constantly expanding. Kwa mfano, 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.
