Vorteile des Faser-Bragg-Gitter-Pipeline-Drucksensors:

OFSCN® Faser-Bragg-Gitter (FBG) pipeline pressure sensor has many significant advantages over traditional electrical sensors:

Strong anti-electromagnetic interference: The optical fiber used in OFSCN® Fiber Bragg Grating pipeline pressure sensor is an insulator und is not affected by electromagnetic waves. It is very suitable for use in dangerous places such as strong electromagnetic environment, high voltage or flammable und explosive places, avoiding measurement errors or equipment damage caused by electromagnetic interference.

Intrinsic safety: OFSCN® Fiber Bragg Grating pipeline pressure sensor is a passive device, not charged, avoiding dangers such as electric sparks, so it is very suitable for pipeline pressure monitoring in flammable und explosive environments such as gas, oil und gas, und has extremely high intrinsic safety.

Good corrosion resistance: The optical fiber und packaging materials used in OFSCN® Fiber Bragg Grating pipeline pressure sensor have good chemical stability, are not easily affected by corrosive media, und extend the service life of the sensor in harsh environments.

Small size und light weight: OFSCN® fiber Bragg grating pipeline pressure sensor has a conventional diameter of 1.1mm und is very thin, making the sensor small und light, easy to integrate into the pipeline system, especially suitable for occasions with limited space or lightweight design.

Long transmission distance und low loss: The optical signal in OFSCN® fiber Bragg grating pipeline pressure sensor has a long transmission distance in the optical fiber with low loss, which can realize long-distance distributed monitoring, reduce the need for relay equipment, und reduce system complexity und cost.

Starke Wiederverwendbarkeit und einfache Vernetzung: Mehrere Faser-Bragg-Gitter-Sensoren können in Reihe an einer optischen Faser angeschlossen werden, um eine Mehrpunkt- und verteilte Messung zu realisieren, was die Verkabelung erheblich vereinfacht, die Systemintegration verbessert und die Gesamtkosten reduziert.

High sensitivity und fast response speed: OFSCN® fiber Bragg grating pipeline pressure sensor responds sensitively to changes in pressure, can capture tiny pressure fluctuations in real time und accurately, has a fast response speed, und is suitable for dynamic monitoring.

Good long-term stability: The physical und chemical properties of the materials used in OFSCN® FBG pipeline pressure sensors are stable, so that OFSCN® FBG pipeline pressure sensors can still maintain high measurement accuracy und stability with small drift during long-term use.

Einfache Fernüberwachung: In Kombination mit Glasfaserkommunikationstechnologie ist es einfach, eine Fernüberwachung und Datenübertragung des Pipeline-Drucks in Echtzeit zu realisieren, was für die zentralisierte Verwaltung und Fehlerdiagnose praktisch ist.

With its unique advantages, OFSCN® FBG pipeline pressure sensors have shown great application potential in the field of pipeline pressure monitoring in industries such as petroleum, natural gas, chemical industry, und water conservancy.

Examples of measurement objects of OFSCN® FBG Pipeline Drucksensor:

Common measurement objects of OFSCN® FBG Pipeline Drucksensor

The measurement objects of OFSCN® FBG Pipeline Drucksensor 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:

Flüssigkeitsdruck in der Pipeline:

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

Pipeline-strukturbezogener Druck:

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, und 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 und 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.
Umweltbezogener Druck:

Porenwasserdruck: Im Bauingenieurwesen, insbesondere bei Dämmen, Hängen, unterirdischen Strukturen usw., ist die Überwachung des Porenwasserdrucks im Boden oder Gestein entscheidend für die Beurteilung der Stabilität und potenzieller Katastrophen (wie Erdrutsche).
Geologischer Druck/Erddruck: Die Messung des Drucks von Boden oder Gestein auf vergrabene Pipelines oder Strukturen hilft, die Auswirkungen geologischer Aktivitäten (wie Erdbeben, Setzungen) auf Pipelines zu bewerten.

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

Direkter Mediumdruck: Der Druck von Gas oder Flüssigkeit innerhalb der Pipeline.

Äquivalenter Druck, verursacht durch Kraft oder Dehnung: Wenn die Pipeline äußeren Kräften (wie Bodenlast, strukturelle Verformung) ausgesetzt ist, reflektiert oder leitet der Sensor den auf die Pipeline wirkenden Druck indirekt ab, indem er die Dehnung des Pipeline-Materials misst.
