Examples of measurement objects of OFSCN® FBG 파이프라인 압력 센서:

Common measurement objects of OFSCN® FBG 파이프라인 압력 센서

The measurement objects of OFSCN® FBG 파이프라인 압력 센서 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:

파이프라인 내 유체 압력:

Gas pressure: Natural gas pipeline, coal gas pipeline, chemical gas pipeline, etc. By monitoring the pressure of gas in the pipeline with OFSCN® FBG 파이프라인 압력 센서, 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 파이프라인 압력 센서 monitors liquid pressure to help find leaks, evaluate transportation efficiency, and monitor the flow pressure of fluids in specific applications.

파이프라인 구조 관련 압력:

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, 및 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 및 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.
환경 관련 압력:

공극수압: 토목 공학, 특히 댐, 사면, 지하 구조물 등에서 토양 또는 암반 내 공극수압을 모니터링하는 것은 안정성 및 잠재적 재해(산사태 등) 평가에 매우 중요합니다.
지질 압력/토압: 매설된 파이프라인 또는 구조물에 대한 토양 또는 암석의 압력을 측정하는 것은 지질 활동(지진, 침하 등)이 파이프라인에 미치는 영향을 평가하는 데 도움이 됩니다.

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

직접 매체 압력: 파이프라인 내부의 기체 또는 액체의 압력.

힘 또는 변형으로 인한 등가 압력: 파이프라인이 외부 힘(토양 하중, 구조 변형 등)을 받을 때, 센서는 파이프라인 재료의 변형을 측정하여 파이프라인에 작용하는 압력을 간접적으로 반영하거나 추론합니다.
