Distributed fiber optic pipeline leakage temperature monitoring sensor, fabrikant, fabrikant

Distributed fiber optic sensors themselves have the characteristics of light weight, small size, easy installation, high sensitivity, resistance to electromagnetic interference, corrosie ferset, no electric sparks, and can achieve distributed and real-time online monitoring. They can replace traditional electrical sensors to complete strong electromagnetic interference, strong corrosiveness, distributed and real-time online temperature, vibration and other signal detection in long-distance environments. Yn de lêste jierren, fiber optic sensing detection technology has been widely used in coal mine fire monitoring, tunnel fire monitoring, gas pipeline leakage detection and other fields. The application of distributed fiber optic temperature measurement technology in pipeline safety monitoring will have excellent prospects.

Principle of Ferdield Fiber Optic Pipeline Leakage Temperature Measurement

After a pipeline leak occurs, the temperature near the leak site will change. Crude oil needs to be transported by heating. If there is a leak in the pipeline, the temperature around the leak point will increase; For gas pipelines, due to the Joule Thomson effect, the temperature around the leakage point of the gas pipeline will decrease. To this end, FJINNO provides a distributed fiber optic temperature detection method based on spontaneous Raman scattering effect and optical time domain reflection principle for distributed and real-time online monitoring of pipeline safety, which determines whether the pipeline leaks based on changes in temperature at the leakage point.
Fiber Optic temperatuer mjitting systeem monitors the safety status of pipelines based on the detection of temperature along the pipeline. In response to the detection requirements for small temperature changes caused by leaks along long-distance pipelines or large temperature changes caused by fires, it has been experimentally demonstrated that the system can achieve a temperature measurement accuracy of ± 1 ℃ within a temperature monitoring distance of 10km, with a temperature measurement range of -25 ℃~+200 ℃, a positioning accuracy of ≤ 2m, and a system dynamic response time of<3s. And it has been verified through on-site experiments that the system can quickly determine and accurately locate the location of pipeline leakage points or fire incidents. The proposal of this system can provide reference and guidance for distributed and real-time online safety monitoring and early warning of long-distance pipelines, and will have good application prospects in pipeline safety monitoring.
