従来のセンサーと比較した光ファイバーセンサーの利点は何ですか

光ファイバーセンサー 今日の人々の生活に馴染みのあるものではありません, 人々の生活のさまざまな側面に応用できるため、, 温度や湿度の測定など, 圧力測定, 振動測定, 等. 従来のセンサー技術は、それほど多くの測定ニーズに適応できない可能性があります.

(1) 高感度. 光ファイバーセンサーの応答速度は非常に速いです, 測定できるさまざまな物理値も非常に小さい.

(2) 電磁妨害防止, 電気絶縁, 耐食性, 本質安全防爆と本質安全化.

光ファイバー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ています, 安全で信頼性の高い耐食性伝送媒体, さまざまな大型電気機械設備で便利かつ効果的に使用できます。, 石油化学, 強い電磁干渉と可燃性および爆発性を伴う鉱山およびその他の過酷な環境.

(3) Fast measurement speed. Light has the fastest propagation speed and can transmit two-dimensional information, making it suitable for high-speed measurements. The analysis of radar and other signals requires a very high detection rate, which is difficult to achieve using electronic methods. High speed spectral analysis using the diffraction phenomenon of light can solve this problem.

(4) Large information capacity. The measured signal is carried by light waves, and the frequency of light is extremely high, which can accommodate a wide frequency band. The same optical fiber can transmit multiple signals.

(5) Suitable for harsh environments. Fiber optic is a dielectric material that is resistant to high voltage, 腐食, 電磁干渉. It can be used in harsh environments that other sensors are not suitable for.

加えて, fiber optic sensors also have the characteristics of light weight, 小型, 柔軟性, wide range of measurement objects, good reusability, そして低コスト. The application of fiber optic sensors is precisely because fiber optic sensors have so many advantages, making their application fields very extensive, involving many fields such as petrochemicals, 電気, 薬, 土木工学, 等.

FJINNO’s fiber optic sensors are fully capable of meeting the higher demands of the high-end market for ultra long distance, ultra high precision, and ultra high sensitivity that cannot be achieved by electrical sensing and general fiber optic sensing.

Compared with traditional sensing technologies, fiber-optic sensors have the following major advantages:

1. 軽量, コンパクトな構造, and easy to reuse multiple times;

2. Resistance to harsh environments, 電磁干渉, and chemical corrosion;

3. At the sensing point, there is no need for electricity and long-distance distributed sensing is possible;

4. Can be mass-produced at low cost

After fiber optic communication, fiber optic sensing has also ushered in important development opportunities. It has broad and enormous application value in security, 軍隊, 石油/ガス, 電気, そして科学的研究, and its future is limitless.

The transmission fiber for 光ファイバー温度測定 is generally quartz fiber, which has the characteristics of corrosion resistance and long service life, 通常は次の目的で使用できます 30 年. Taking into account the cost of the sensor itself and future maintenance costs, the use of fiber optic sensors can greatly reduce the final operating cost of the entire project.

Compared with electronic systems, the advantages of fiber optic systems are mainly reflected in the high safety, 良い安定性, and long lifespan of sensors. The main application areas are power systems (underground, 架空線), 防火システム (traffic tunnels), 橋, 石油化学製品 (パイプライン, stations/valve chambers), 水の保全, 等. 現在のところ, the most popular technology is 分散型光ファイバー 振動検知, which is applied in various security fields. In some niche markets, technologies such as active/passive infrared targeting, レーザーターゲティング, leaky cables, and vibrating cables have gradually been replaced. Fiber optic sensors have a simple structure, 高精度, 高感度, and are easy to implement in many environments, making them currently very popular.

Disadvantages of non-contact temperature sensors: 1. They are easily affected by environmental factors, such as thermal radiation. 2. They are not easy to achieve long-term continuous measurement of targets.

Advantages of contact temperature sensors: stable measurement and high accuracy; The disadvantage of non-contact temperature sensors is, 順番に, the disadvantage of contact sensors.

Thermal infrared sensor: The advantage is that it can be operated at room temperature, and wavelength dependence does not exist, making it inexpensive; The disadvantage is low sensitivity and slow response.

Quantum type infrared sensor: Its advantages are high sensitivity and fast response; The disadvantages are that it must be cooled (liquid nitrogen), wavelength dependent, and expensive.

Ultrasonic sensor: Its advantages include high frequency, short wavelength, small diffraction phenomenon, especially good directionality and the ability to become rays and propagate in a directional manner; The disadvantage is the presence of triangulation errors, which are easily affected by noise.
