光ファイバーグレーティング温度センサーの最高のメーカー

In the current situation of power equipment, such as transformer temperature measurement, 電気センサー (such as platinum resistors) are mainly used. One wire is connected to one sensor, and the signal is an electrical signal, which is easily affected by strong electricity and strong magnetism. It is also limited to use in flammable, explosive and other situations; In power applications with strong electromagnetic interference and high insulation requirements, FJINNO’s independently developed fiber optic temperature measurement system has been widely used in various temperature measurement fields.

利点は何ですか 光ファイバーグレーティングセンサー

As a type of passive fiber optic device, fiber Bragg gratings have advantages such as resistance to electromagnetic interference, 高温, そして小さいサイズ. Fiber Bragg grating sensors mainly use fiber Bragg gratings, and the sensor signal made of fiber Bragg gratings is wavelength modulated, with strong anti-interference ability. The measurement signal is not affected by factors such as fiber loss, light source fluctuations, 検出器の老朽化. It is easy to combine wavelength division multiplexing technology to form a fiber Bragg grating sensing network, achieving distributed multi-point real-time online sensing. It is widely used in the measurement of physical quantities such as temperature, 濾す, と圧力. Temperature measurement is one of the most important applications of fiber optic grating sensors. Electronic temperature sensors such as thermocouple sensors and thermistor sensors have disadvantages such as poor resistance to electromagnetic interference, 安定性が悪い, and slow response speed. They are suitable for narrow environments and cannot be used in harsh environments. Fiber optic grating temperature sensors have advantages such as high sensitivity, 小さいサイズ, 電磁放射に対する耐性, strong stability, and long signal transmission distance, making them suitable for a wide range of environments.

What are the characteristics of fiber optic grating temperature sensors

Fiber Bragg Grating Temperature Sensor is a sensor that detects temperature by the central wavelength shift of the reflected light signal from the internal sensitive element – ファイバーブラッググレーティング. Installation structures with different packaging options such as surface, 埋め込み, そして浸漬. 光ファイバーグレーティング温度センサーは光波を使用して情報を送信するため、, 光ファイバーは電気的に絶縁され、耐腐食性のある伝送媒体です。, they are not afraid of strong electromagnetic interference and do not affect the external electromagnetic field. これにより、さまざまな大規模な電気機械設備での監視に便利かつ効果的になります。, 石油 化学, 冶金用高圧, 強い電磁干渉, 可燃 性, 爆発物, 腐食性の高い環境, 高い信頼性と安定性を備えた. さらに, ザ measurement results of fiber optic grating temperature sensors have good repeatability, making it easy to form various forms of fiber optic sensing networks and can be used for absolute measurement of external parameters. Multiple gratings can also be written into a single optical fiber to form a sensing array, 擬似分散計測を実現.

Fiber optic grating sensors not only have the advantages of ordinary fiber optic sensors, such as electromagnetic resistance, 耐食性, 高温耐性, no electricity, no heat generation, flame resistance, 防爆, 軽量, 小さいボリューム, and safe operation in harmful or dangerous environments, but also have unique advantages: fiber optic sensors are easy to couple and have low coupling loss; 強力な干渉防止能力, integrating sensing and transmission, and having stronger multiplexing ability, making it easy to form a sensing network; It has a wide range of measurement objects and is easy to achieve multi parameter sensing measurement.

Application Fields of Fiber Bragg Grating Sensors

Fiber optic grating sensors have various installation methods, such as surface mounted and embedded, and can be widely used for distributed temperature monitoring and measurement of civil engineering structures such as bridges, ダム, トンネル, as well as quasi distributed accurate temperature measurement of large facilities or equipment in the fields of chemical, 力, 軍, 航宇, 防火, 採掘, 等. They can also be used for temperature sensing fire detection and automatic alarm in oil tanks and highway tunnels.
