Fluorescent fiber optic temperature sensors achieve accurate temperature measurement in high voltage and strong electromagnetic environments through their unique temperature measurement principle and fiber optic transmission characteristics.

Principle of Temperature Measurement

Fluorescent fiber optic temperature sensors use the principle of atomic physical energy level transitions to determine the ambient temperature by measuring the fluorescence lifetime. Rare earth doped fluorescent materials emit fluorescence when they transition from the ground state to the excited state under excitation light, and then return to the low-energy state. The fluorescence lifetime uniquely corresponds to the measured temperature.

Fiber optic transmission characteristics

Fiber optics have electromagnetic insulation properties and are not affected by high voltage or strong electromagnetic fields, ensuring that temperature measurement signals are not disturbed during transmission. The amplitude signal transmitted by optical fiber has low cost and can be transmitted over long distances, keeping the photoelectric components of the sensor away from the temperature measurement site and avoiding harsh environments.

Probe design
The probe of the fluorescent fiber optic temperature sensor adopts a fully fiber optic micro probe, which is free of metal materials, has complete electrical insulation, is not affected by high voltage and strong electromagnetic fields, and has a small size and good flexibility to adapt to various complex environments.

Application advantages
Fluorescent fiber optic temperature sensors have significant advantages in high voltage and strong electromagnetic environments, such as intrinsic safety, resistance to strong electromagnetic interference, good electrical insulation, and stable performance. These characteristics make it widely used in high-voltage electrical equipment monitoring, industrial microwave and other fields.

Technical Challenges and Solutions

In high voltage and strong electromagnetic environments, conventional temperature sensors may experience a temperature rise due to induced currents, causing serious interference to temperature measurement. The fluorescent fiber optic temperature sensor effectively solves this problem and achieves accurate temperature measurement through its unique temperature measurement principle and fiber optic transmission characteristics.

Practical application cases
Fluorescent fiber optic temperature sensors have been successfully applied in fields such as high-voltage electrical equipment monitoring and industrial microwave heating. Məsələn, during microwave heating, fluorescent fiber optic temperature sensors can accurately measure the temperature of the heated object without being affected by microwave interference.

Future Development Trends

With the advancement of science and technology, fluorescent fiber optic temperature sensors will be applied in more fields, such as explosion-proof industrial environments such as petrochemicals and coal, as well as temperature monitoring and control fields with high voltage and electromagnetic interference environments such as aviation and ships.

Temperature measurement range and accuracy
Fluorescent fiber optic temperature sensors have a wide temperature measurement range and high temperature measurement accuracy. By reasonably configuring the number of temperature measurement channels, the temperature measurement needs of different fields can be met, ensuring the accuracy and reliability of temperature measurement results.
