最高の光ファイバー温度監視メーカーガイド

1、 選ぶときのポイント 光ファイバー温度監視メーカー

（1）製品性能関連
測定範囲
アプリケーションシナリオが異なれば、温度測定範囲の要件も異なります。. 例えば, 冶金などの産業環境で, 高温炉の温度を監視する必要がある場合があります, 摂氏数百度、あるいはそれ以上に達することもあります; 一部の電子機器の温度監視において, 温度範囲は比較的狭い場合があります。 -40 °C°C -+80 °C°C. メーカーが提供する光ファイバー温度監視製品の温度測定範囲が実際に必要な温度範囲をカバーできない場合, 使用要件を満たせません. 例えば, およその融点を持つ金属の温度を監視する 200 加熱工程時℃, 選択した光ファイバー温度監視製品の温度上限は、 200 °C°C, そうしないと正確な温度データが得られません.
温度測定精度
製品の測定精度を測る重要な指標です. 温度変化に敏感なデバイスまたはプロセス向け, 精密電子機器の放熱監視や化学反応の温度管理など, 高精度の温度測定が重要です. 一般的に言えば, 厳密な定義によれば, 温度測定精度は測定値と真の値の差です。. 警報装置に関しては, 未満の偏差 5% 通常は許容されます, 未満の偏差を達成する 3% 優れていると考えられています. 例えば, 電力設備の温度監視に, 精度が十分でない場合, 誤った判断を招く可能性がある. For oil temperature monitoring of transformers, when the actual temperature rises by 10 °C°C, if the measurement accuracy deviation is too large, it may not trigger a warning, thus ignoring the potential risk of equipment failure.
応答時間
In some rapidly changing industrial scenarios or temperature measurement experiments in the power cable industry, the speed of response time determines work efficiency. If a thermometer can quickly detect temperature, it will have an advantage in various dynamic temperature measurement industry scenarios. 例えば, in the process of power inspection, if the overheating phenomenon of the faulty part of the detection equipment is detected, and the response time is too long, it may miss the best detection and warning opportunity, thereby affecting the safety and stability of the power system.
Spatial resolution and sampling rate (applicable to 分散型光ファイバー 温度監視)
空間解像度, also known as responsivity, refers to how long the optical cable of the system needs to be under the temperature field in order to accurately measure temperature. This indicator is particularly important when measuring temperature through thermal conduction, such as monitoring temperature with optical cables, laying oil pipelines, or detecting fires. 例えば, in tunnel fire detection, if the responsiveness of the entire fiber optic sensing system is poor, it may lead to false alarms when a fire occurs, which is a very serious defect. 現在は, 技術的な限界のため, the world limit for Raman fiber temperature measurement is around 0.5 メートル.
サンプリングレート: refers to the sampling density of the temperature measuring optical cable by the system, それです, the distance at which temperature data is returned. Determined by the signal processing system of the system, according to sampling theory, it should be at least twice the signal bandwidth. From the perspective of signal restoration in engineering, it is advisable to use 3-5 倍. 例えば, a signal bandwidth can be equivalent to a spatial responsivity of 3 meters in the system, and a sampling rate of 1 メーター (すなわち、. 100MHz) is more appropriate, but cannot exceed 1.5 メートル.
（2） Product type and applicability related
Single point or distributed
Determine whether to use “配布された” 又は “単一点” 必要な測定点の数に基づいたセンサー. If the number of measurement points is less than 50, ある “単一点” センサー, such as a fluorescent sensor, is usually used; 以上の場合 50 測定ポイント, “配布された” sensors such as fiber Bragg grating sensors are generally used. 例えば, when monitoring the temperature of key equipment in a small computer room with a small number of devices, a single point 光ファイバー温度センサー can be selected; If temperature monitoring is to be carried out along oil pipelines that are several kilometers long, distributed fiber optic temperature sensors are more suitable due to the large number of monitoring points required.
プローブ動作タイプ
浸漬型: It can be used to measure the temperature of solids, 液体, そしてガス, and after special treatment, the optical fiber has strong strength and toughness, 液体タンク内の化学腐食に耐えることができます. 例えば, this type of probe can be used in temperature measurement of industrial liquid tanks, such as temperature monitoring of liquid in reaction vessels in chemical production. Corrosive chemicals may exist in the reaction vessel, and immersion probes can resist corrosion while measuring temperature.
Contact type: specifically used to measure the temperature of object surfaces, temperature monitoring of high-voltage equipment such as dry-type transformers, 高電圧開閉装置, and high-voltage busbars relies on contact type probes. 高圧開閉装置内, contact probes are used to monitor the temperature of the contacts in order to detect overheating in a timely manner and prevent equipment failures and safety accidents.
Medical type: specially designed for life science measurement, the probe is small and thin, and with a dedicated demodulator, 速い応答速度と非常に高い精度を実現できます。. 例えば, in biomedical experiments, measuring the temperature of cells or small biological samples, medical grade fiber optic temperature sensors can accurately meet demand 2.

3、 Evaluation criteria for fiber optic temperature monitoring manufacturers
（1） Measurement performance indicators
check the accuracy
High precision measurement is a fundamental requirement for fiber optic temperature monitoring. According to a strict definition, detection accuracy is the difference between the measured value and the true value, and the smaller the difference, より良い. 例えば, in a laboratory environment, a high-precision standard thermometer and the fiber optic temperature monitoring product to be evaluated are used to measure a known temperature sample simultaneously, and the product accuracy is determined by comparing the measured values of the two. In practical application scenarios, such as temperature monitoring of aerospace equipment, if the accuracy does not meet the standard, it may lead to flight safety hazards; Insufficient monitoring accuracy of reactor temperature in the pharmaceutical industry can also affect drug quality.
解像力
温度分解能: reflects the minimum temperature change that the product can detect. 例えば, a fiber optic temperature monitoring system with a temperature resolution of 0.1 ℃ means it can sense temperature changes up to 0.1 °C°C. In some temperature sensitive scenarios, such as temperature monitoring during semiconductor chip manufacturing, high temperature resolution is crucial because even small temperature fluctuations during chip manufacturing can affect chip quality.
空間解像度 (applicable to distributed systems): This is particularly important for distributed fiber optic temperature monitoring systems, as it is related to the accuracy and sensitivity of temperature measurement in the system. The extremely low spatial resolution value indicates that the system can more accurately locate the location where temperature changes occur. 例えば, in earthquake monitoring, the temperature characteristics of optical fibers are used to detect small temperature changes in underground rock layers. High spatial resolution optical fiber temperature monitoring systems can more accurately determine the location of temperature anomalies and reflect potential signs of seismic activity.
安定性
The measurement stability of products under different environmental conditions and long-term use is an important evaluation aspect. Stable measurement results are necessary to provide reliable temperature data basis for practical applications. 例えば, in harsh outdoor environments such as high temperature, 湿度, or strong vibration, fiber optic temperature monitoring products can maintain measurement accuracy without significant changes after long-term use, which is a manifestation of good stability. In the blade temperature monitoring project of wind farms, if the fiber optic temperature monitoring equipment is unstable, it may obtain incorrect temperature data, which will affect the judgment of the blade status.
（2） Product reliability
耐用年数
A longer service life means that the product can continue to function normally throughout its entire lifecycle, reducing the frequency and cost of replacing equipment. 例えば, in large industrial facilities such as power plants and refineries, if the fiber optic temperature monitoring equipment frequently malfunctions and needs to be replaced, it will not only increase costs but may also affect the normal production process. 一般的に言えば, factors such as material quality, manufacturing process, and internal structural design of a product can affect its service life. The use of high-quality fiber optic materials, advanced sensor packaging technology, and reasonable circuit structure design can all help improve the service life of the product.
耐干渉能力
There are various interference factors in practical application environments, 電磁妨害など, 化学腐食, physical vibration, 等. Fiber optic temperature monitoring equipment needs to have sufficient anti-interference ability to ensure accurate temperature measurement. The anti-interference ability of the product is reflected in the protection design of the equipment, 信号処理アルゴリズム, およびその他の側面. 例えば, 強い電磁干渉のある産業環境, fiber optic temperature monitoring probes near high-voltage equipment may be affected by electromagnetic pulses. If the product has good electromagnetic shielding and signal filtering design, it can work normally without interference. In the vicinity of chemical pipelines, equipment needs to be corrosion-resistant, and the use of special outer protective materials and sealing designs can enhance the ability to resist chemical corrosion.
互換性
Compatibility with other related devices or systems is also an important aspect of evaluation. 実際のエンジニアリング用途では, fiber optic temperature monitoring systems may need to interface and collaborate with data acquisition systems, 警報システム, monitoring center software, 等. 例えば, in the temperature monitoring system of intelligent buildings, the fiber optic temperature monitoring sensor should be compatible with other sensors in the building control system (湿度センサーなど, 煙センサー, 等。) and the monitoring software of the management, to achieve data integration and linkage control, so as to make the entire intelligent building system operate more efficiently.
