優れた安定性, 極度の低温環境に耐えることができる

従来の電子温度センサーは、極度の低温では性能が急激に低下したり、故障したりすることがありました。, 光ファイバーの温度測定は温度の影響を受けませんが、. 光ファイバー温度測定システムはセンサーとして石英光ファイバーを使用します, 石英材料の融点は 1700 ℃. 極低温環境下でも -200 ℃, the fiber optic sensor can still maintain stable operation without performance degradation. This enables the fiber optic temperature measurement system to be reliably applied in ultra-low temperature situations such as liquid nitrogen, liquid oxygen, and liquid helium, as well as in fields such as low-temperature warehouses and cold chain logistics.

High precision and excellent temperature resolution

の光ファイバー温度測定システム utilizes the afterglow principle of fluorescent fiber optic to calculate the temperature of the environment in which the fiber optic is located by analyzing the instantaneous duration change of the fluorescent fiber optic. This temperature measurement principle determines that it has extremely high measurement accuracy and temperature resolution, and has obvious advantages compared to traditional temperature measurement components such as platinum resistors and thermocouples. High precision temperature measurement data can provide reliable basis for precise control of low-temperature environments.

本質安全防爆, non electric and passive
The fiber optic itself is an electrical insulator. In the process of fiber optic temperature measurement, the fiber optic sensor does not contain any electronic components, and there is no current generation or flow. This inherent safety feature enables fiber optic temperature measurement systems to be safely applied in flammable and explosive environments, such as low temperature environments such as oil, 天然ガス, coal mines, 等. その間, due to the absence of source devices, fiber optic sensors do not require separate power supply, eliminating the worry of power failure and greatly improving system reliability.

電磁妨害防止, more reliable measurement results
In a strong electric field environment, electronic temperature sensors are susceptible to electromagnetic interference, resulting in a decrease in temperature measurement accuracy. Fiber optic is completely unaffected by electromagnetic fields, and optical signals are not contaminated or attenuated. したがって, the measurement results of the fiber optic temperature measurement system are more accurate and reliable, making it very suitable for temperature monitoring in low-temperature areas with strong electromagnetic environments such as substations and power plants.

小型, 軽量, flexible installation and use
Fiber optic sensors have a small diameter, 軽量, good flexibility, and can be bent freely, making installation very convenient. It has a small thermal contact area with the low-temperature tested object, small thermal inertia, そして応答速度が速い. The characteristics of small size and light weight also make it easier to integrate fiber optic temperature measurement systems into various low-temperature equipment and devices.

Long lifespan with less maintenance, reducing usage costs
The fiber optic sensor is made of high-purity quartz glass, which has no mechanical wear and a long working life. Its optical performance has undergone strict screening and aging experiments, and its long-term stability is good. Fiber optic cables have strong corrosion resistance, 高耐電圧, and tensile resistance, and can maintain performance under various harsh working conditions. The fiber optic temperature measurement system is calibration free and maintenance free, with low operating costs and high return on investment.

要約すれば, fiber optic temperature measurement technology has many advantages such as good stability, 高精度, 本質安全防爆, 干渉防止, small volume, 広い範囲, そして長寿命, and has obvious technical advantages and application value in zero to low temperature environment monitoring. 将来, with the further development of fiber optic sensing technology, fiber optic temperature measurement will be more widely used in the field of low-temperature measurement.
