The fiber optic temperature sensor adopts a temperature sensing material made of rare earth material, which is stable for a long time. The outer layer of the sensor is equipped with a special sheath, which is explosion-proof and flame proof to ensure the safety and reliability of the system. It is small in size, lightweight, and non-toxic;
The fiber optic temperature measurement system has a temperature measurement cycle of less than 1 Dezyèm, which can fully ensure the timeliness of alarms; The fiber optic temperature transmitter has a small volume and is easy to install.

The principle of the specialized fluorescent fiber temperature sensor used in medical fiber optic temperature measurement devices is based on fluorescence afterglow temperature measurement technology, internationally advanced optical temperature measurement, and stable performance; All optical signal temperature measurement, non-conductive structure, completely immune to electromagnetic interference; The sheath is soft and wear-resistant, convenient to use, and suitable for medical scenarios; The probe and optical interface form are specified.

In the medical field, many diagnostic or therapeutic techniques may cause an increase in the temperature of a patient’s body parts. For safety and treatment optimization purposes, it is necessary to be able to accurately monitor the temperature of tissues in contact with these technologies, as well as the temperature of materials that may come into contact with patients. Fluorescent fiber optic temperature probes are non-conductive and fully suitable for applications with strong magnetic fields, microwave (MW), and radio frequency (RF) currents. The installation of fluorescence fiber temperature measurement and temperature measurement integrated device in microwave hyperthermia equipment solves the problem of real-time temperature monitoring that cannot be achieved synchronously in the existing microwave hyperthermia process, which is conducive to improving the effectiveness of hyperthermia and improving the safety and reliability of microwave hyperthermia. Nan endistri medikal la, se mezi tanperati optik aplike nan zòn tankou terapi mikwo ond ak ipèrmia, frekans radyo ak rezon mayetik. Anpil pwojè enplike metòd tretman ki mande pou siveyans tanperati egzak. Sepandan, nan mikwo ond mikwo-onn, entèferans nan mikwo ond oswa frekans radyo ka fasilman afekte presizyon nan rezilta mezi tanperati. Rezon ki fè tanperati mezi a afekte se ke si pwobabilite tanperati a te fè nan materyèl metal, li fasil pou jenere kouran an nan jaden mikwo ond lan, ak rezilta mezi tanperati yo pral entèfere ak. Tanperati a vre nan tisi timè pa ka byen mezire, ki afekte rezilta tretman yo. Yon lòt bagay se terapi tèmik nan tretman medikal, ki sitou mezire tanperati a chofe timè a nan yon tanperati ki efikas ki ka geri ou. Si tanperati timè a anba tanperati a tretman, li ka ankouraje pwopagasyon tisi timè. Si tanperati a nan timè a twò wo, li ka tou domaje tisi nòmal. Se poutèt sa, mezi fib egzat optik tanperati a se yon mwayen enpòtan nan mikwo-onn hypermia. Iminite elektwomayetik/radyo frekans, rezistans korozyon, segondè presizyon ak fyab yo se chwa pou mezire tanperati nan jaden medikal la.

Practical application cases of medical fluorescent fiber optic temperature sensors

The fluorescence lifetime fiber optic temperature sensing probe of fluorescence lifetime fiber optic temperature sensing technology is based on the material properties of rare earth fluorescent substances. When certain rare earth fluorescent substances are irradiated and excited by ultraviolet light, they emit a linear spectrum in the visible spectrum, namely fluorescence and its afterglow (afterglow is the luminescence after excitation stops). The decay time constant of fluorescence afterglow is a single valued function of temperature, and usually the higher the temperature, the smaller the time constant. As long as the value of the time constant is measured, the temperature can be calculated. The biggest advantage of using this method for temperature measurement is that the measured target temperature only depends on the time constant of the fluorescent material, and is independent of other variables in the system, such as changes in light source intensity, transmission efficiency, coupling degree, elatriye, which do not affect the measurement results. It has obvious advantages in principle compared to other temperature measurement methods.
