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, 유전, and underground. 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, 고온, and explosion-proof coal mine requirements in the vicinity.
The distributed fiber optic temperature sensing system mainly consists of distributed fiber optic demodulators, temperature sensing fibers, 등. The function of the fiber optic demodulator is to process and upload fiber optic signals, set temperature alarms and technical requirements, 등. 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. Over time, in the event of natural disasters such as direct sunlight, high temperatures, 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 fiber optic temperature sensor is a newly developed linear fiber optic temperature detector. Distributed fiber optic has the advantages of intrinsic explosion-proof, strong electromagnetic interference resistance, 낙뢰 보호, 고온 측정 정확도, 경량, 그리고 긴 서비스 기간. 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. 더욱이, fiber optic is a transmission medium and also a temperature sensor, without the need for external temperature sensors. Distributed fiber optic installation is simple, reliable, 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, Transmission and Sensing 통합; 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) 측정 사각지대가 없는 지속적인 분산 측정: DTS는 연속 분산 측정에 속하며 감지 광 케이블을 따라 각 지점의 온도를 얻을 수 있습니다. 현재, 인접한 온도 지점 사이의 거리 간격은 최대 0.25m에 달할 수 있습니다., with rich temperature information and no measurement blind spots; And based on continuous temperature analysis, 지역 온도 차이 경보를 달성할 수 있습니다..
(3) 추후 운영 및 유지보수를 위한 낮은 작업량: DTS의 감지 광케이블은 실외 통신 광케이블을 기반으로 설계되었습니다, 그리고 통신 광케이블의 수명은 최대 도달할 수 있습니다. 30 년; The core components of the DTS measurement host (such as light sources, splitters, 등.) 설계된 수명을 가진 모든 통신 등급 장치입니다. 100000 시간 (이상 10 년). 호스트에는 온도 교정 장치와 오류 자체 점검 모듈이 장착되어 있습니다, 안정적이고 신뢰할 수 있는 온도 측정 보장.
