Examples of measurement objects of OFSCN® FBGパイプライン圧力センサー:

Common measurement objects of OFSCN® FBGパイプライン圧力センサー

The measurement objects of OFSCN® FBGパイプライン圧力センサー mainly revolve around the pressure changes inside or outside the pipeline, which are usually caused by the medium in the pipeline, deformation of the pipeline structure or external environmental factors. Specific measurement objects include:

パイプライン内の流体圧力：

Gas pressure: Natural gas pipeline, coal gas pipeline, chemical gas pipeline, etc. By monitoring the pressure of gas in the pipeline with OFSCN® FBGパイプライン圧力センサー, it can be determined whether there is leakage, blockage or abnormal fluctuation.
Liquid pressure: Oil pipeline, water (tap water, sewage, pore water) pipeline, chemical liquid pipeline, etc. OFSCN® FBGパイプライン圧力センサー monitors liquid pressure to help find leaks, evaluate transportation efficiency, and monitor the flow pressure of fluids in specific applications.

パイプライン構造関連の圧力：

Pressure caused by strain: When the pipeline is subjected to external loads (such as soil settlement, geological disasters, vehicle rolling, etc.) or the internal pressure is too high, the pipeline itself will undergo slight deformation (strain). OFSCN® Fiber Bragg Grating Pipe Pressure Sensor can convert this strain into an equivalent pressure signal for measurement. This is actually an indirect measurement of structural stress or pressure.
Pipe-soil interface pressure: Buried pipelines are in the soil, および the soil will exert pressure on the pipeline. Monitoring the pipe-soil interface pressure through OFSCN® Fiber Bragg Grating Pipe Pressure Sensor can evaluate the impact of soil on the pipeline, especially in disaster areas such as landslides および subsidence.
Pressure in equipment or devices: In some industrial equipment or mechanical devices, OFSCN® Fiber Bragg Grating Pipe Pressure Sensor can measure the pressure of its internal or associated pipelines, such as drilling equipment, reactors, storage tanks, pump bodies in refineries or chemical plants, etc.
環境関連の圧力：

間隙水圧：土木工学、特にダム、斜面、地下構造物などで、土壌または岩盤中の間隙水圧を監視することは、安定性および潜在的な災害（地すべりなど）を評価するために不可欠です。
地質圧力/土圧：埋設されたパイプラインや構造物にかかる土壌や岩石の圧力を測定することで、地質活動（地震、地盤沈下など）がパイプラインに与える影響を評価するのに役立ちます。

In summary, the 'pressure' measured by OFSCN® fiber Bragg grating pipeline pressure sensor can be divided into two categories:

直接媒体圧力：パイプライン内の気体または液体の圧力。

力またはひずみによる等価圧力：パイプラインが外部力（土壌荷重、構造変形など）にさらされると、センサーはパイプライン材料のひずみを測定することで、パイプラインにかかる圧力を間接的に反映または推測します。
