Penderia suhu gentian optik INNO ,sistem pemantauan suhu.
Dalam beberapa tahun kebelakangan ini, prefabricated insulation pipelines for urban centralized heating and cooling have developed rapidly in China and have been widely used. Pipeline leakage detection is clearly an important component of maintenance activities and has always been a challenging task. Dalam kebanyakan kes, on-site inspections of pipelines are required to identify leakage points.
In the past few years, the use of fiber optic distributed temperature monitoring technology has been proven to be an effective method for detecting and locating pipeline leaks, melalui penggunaan pengukuran pantulan domain masa optik (OTDR) teknologi untuk penyetempatan. Sebagai medium untuk pengesanan suhu, cara menyusun dan membina kabel optik dengan munasabah, dan cara meletakkannya dengan lebih baik dan lebih berkesan di pelbagai kawasan rupa bumi khas untuk memastikan kualiti pembinaan peletakan adalah asas ketepatan pengukuran suhu gentian optik dan keutamaan utama untuk penggunaan yang cekap di peringkat seterusnya.
The fiber optic distributed pipeline monitoring system uses fiber optic as a sensor to detect pipeline leakage points by monitoring temperature changes outside the pipeline. The main principle of the DTS fiber optic distributed pipeline monitoring system is the Raman effect. Cahaya hamburan Raman disebabkan oleh getaran molekul yang dipengaruhi oleh haba, dan cahaya berselerak belakang membawa maklumat tentang suhu setempat di mana penyerakan berlaku.
Sistem pengukuran suhu gentian optik teragih: The system mainly consists of a distributed fiber optic temperature demodulator and a temperature measurement optical cable. The distributed fiber temperature demodulator is a distributed temperature sensing system (DTS) that continuously measures the ambient temperature of the fiber optic. It uses advanced OTDR technology and Raman scattering light’s temperature sensitive characteristics to detect temperature changes along different positions of the fiber optic, achieving truly distributed temperature measurement and positioning. As a mature fiber optic distributed temperature measurement kaedah, this device has the advantages of long measurement distance, ketepatan pengukuran yang tinggi, kelajuan tindak balas yang cepat, anti gangguan elektromagnet, portability, dll., and can be widely used for leakage monitoring in heating pipeline networks.
