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, medan minyak, dan bawah tanah. 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, suhu tinggi, and explosion-proof coal mine requirements in the vicinity.
The gentian optik teragih temperature sensing system mainly consists of distributed fiber optic demodulators, temperature sensing fibers, dll. The function of the fiber optic demodulator is to process and upload fiber optic signals, set temperature alarms and technical requirements, dll. 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. Lama kelamaan, in the event of natural disasters such as direct sunlight, suhu tinggi, dan kilat, 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 sensor suhu gentian optik is a newly developed linear fiber optic temperature detector. Distributed fiber optic has the advantages of intrinsic explosion-proof, rintangan gangguan elektromagnet yang kuat, perlindungan kilat, ketepatan pengukuran suhu tinggi, ringan, dan hayat perkhidmatan yang panjang. 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. Lebih-lebih lagi, fiber optic is a transmission medium and also a temperature sensor, without the need for external temperature sensors. Distributed fiber optic installation is simple, boleh dipercayai, dan prestasinya lebih baik daripada peralatan pengesan suhu tradisional, menjadikannya amat sesuai untuk aplikasi pemantauan suhu kebakaran dalam pengeluar tangki kimia.

Ciri-ciri sistem pengukuran suhu gentian optik teragih DTS

(1) Kabel gentian optik ialah penderia suhu tanpa titik peleburan di tengah, menjadikannya sangat boleh dipercayai. Kabel gentian optik itu sendiri adalah penderia suhu, memainkan kedua-dua peranan pengesan suhu dan peranan penting dalam penghantaran isyarat, mengintegrasikan penghantaran dan penderiaan; Disebabkan ketiadaan komponen penderiaan tambahan dan ketiadaan titik gabungan di tengah-tengah kabel optik penderiaan, ia mempunyai kebolehpercayaan yang tinggi.

(2) Pengukuran teragih berterusan tanpa bintik buta pengukuran: DTS tergolong dalam pengukuran teragih berterusan dan boleh memperoleh suhu setiap titik di sepanjang kabel optik penderiaan. Pada masa ini, selang jarak antara titik suhu bersebelahan boleh mencapai sehingga 0.25m, dengan maklumat suhu yang kaya dan tiada titik buta pengukuran; Dan berdasarkan analisis suhu berterusan, penggera perbezaan suhu serantau boleh dicapai.

(3) Beban kerja yang rendah untuk operasi dan penyelenggaraan kemudian: Kabel optik penderiaan DTS direka bentuk berdasarkan kabel optik komunikasi luar, dan hayat perkhidmatan kabel optik komunikasi boleh mencapai sehingga 30 tahun; Komponen teras hos pengukuran DTS (such as light sources, splitters, dll.) adalah semua peranti gred komunikasi dengan jangka hayat yang direka bentuk sebanyak 100000 jam (lebih daripada 10 tahun). Hos dilengkapi dengan unit penentukuran suhu dan modul semakan sendiri kerosakan, memastikan pengukuran suhu yang stabil dan boleh dipercayai.
