Advantages of Distributed Fiber Optic Linear Thermal Fire Detectors-INNO

The distributed fiber optic linear temperature sensing fire detector is a fiber optic fire alarm device system independently developed based on the principle of Raman scattering. This system can monitor in real time the temperature rise and fall in the area where the temperature sensing fiber is installed in the system. The distributed fiber optic temperature detection device is mainly used for temperature monitoring in a wide range of areas such as power cables, tunnel comprehensive pipe galleries, oil fields, وتحت الأرض. It is particularly suitable for fire temperature sensing in areas where flammable, explosive and other hazardous materials are stored, as well as in government fire protection projects with strong electromagnetic interference, easy corrosion, ارتفاع درجة الحرارة, and explosion-proof coal mine requirements in the vicinity.
ال الألياف الضوئية الموزعة temperature sensing system mainly consists of distributed fiber optic demodulators, temperature sensing fibers, إلخ. The function of the fiber optic demodulator is to process and upload fiber optic signals, set temperature alarms and technical requirements, إلخ. The function of the temperature sensing fiber is to collect the temperature of the measured object.

Distributed Fiber Optic Application Temperature Monitoring System for Oil Storage Tanks

In industrial production, the general chemical storage tanks are mainly floating roof tanks. The sealing at the top of a floating roof oil tank is not absolutely tight, and there is a possibility of a small amount of liquid and gas leakage inside the tank. متأخر , بعد فوات الوقت, in the event of natural disasters such as direct sunlight, درجات حرارة عالية, and lightning, the oil tank is likely to catch fire. Due to the fact that storage tanks are usually located outdoors and have a large volume and total area, it is necessary to install a distributed fiber optic temperature measurement system on the tank.

FJINNO’s DTS distributed مستشعر درجة حرارة الألياف الضوئية is a newly developed linear fiber optic temperature detector. Distributed fiber optic has the advantages of intrinsic explosion-proof, مقاومة قوية للتداخل الكهرومغناطيسي, الحماية من الصواعق, دقة قياس درجات الحرارة العالية, خفيفة الوزن, وعمر الخدمة الطويل. Distributed fiber optic temperature sensors are an important component of distributed temperature fire detectors. Their main feature is that they can detect temperature measurements at any point along the fiber optic line without any blind spots. علاوة على ذلك, fiber optic is a transmission medium and also a temperature sensor, without the need for external temperature sensors. Distributed fiber optic installation is simple, موثوق, and its performance is superior to traditional temperature sensing equipment, making it particularly suitable for fire temperature monitoring applications in chemical tank manufacturers.

The characteristics of DTS distributed fiber optic temperature measurement system

(1) Fiber optic cable is a temperature sensor with no fusion point in the middle, making it highly reliable. Fiber optic cable itself is a temperature sensor, playing both the role of a temperature detector and an important role in signal transmission, integrating transmission and sensing; Due to the absence of additional sensing components and the absence of fusion points in the middle of the sensing optical cable, it has high reliability.

(2) Continuous distributed measurement without measurement blind spots: DTS belongs to continuous distributed measurement and can obtain the temperature of each point along the sensing optical cable. حالياً, the distance interval between adjacent temperature points can reach up to 0.25m, with rich temperature information and no measurement blind spots; And based on continuous temperature analysis, regional temperature difference alarm can be achieved.

(3) Low workload for later operation and maintenance: تم تصميم الكابلات الضوئية للاستشعار الخاصة بـ DTS استنادًا إلى كابلات الاتصالات الضوئية الخارجية, ويمكن أن يصل عمر خدمة كابلات الاتصالات الضوئية إلى 30 سنين; The core components of the DTS measurement host (such as light sources, splitters, إلخ.) كلها أجهزة من فئة الاتصالات ذات عمر مصمم يبلغ 100000 ساعات (أكثر من 10 سنين). تم تجهيز المضيف بوحدة معايرة درجة الحرارة ووحدة الفحص الذاتي للأخطاء, ضمان قياس درجة الحرارة مستقرة وموثوقة.
