Vantaggi del Sensore di Pressione per Condotte a Reticolo di Bragg a Fibra:

OFSCN® Reticolo di Bragg a Fibra (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 e is not affected by electromagnetic waves. It is very suitable for use in dangerous places such as strong electromagnetic environment, high voltage or flammable e 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 e explosive environments such as gas, oil e gas, e has extremely high intrinsic safety.

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

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

Long transmission distance e 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, e reduce system complexity e cost.

Forte riusabilità e facile networking: più sensori a reticolo di Bragg a fibra possono essere collegati in serie su una singola fibra ottica per realizzare misurazioni multipunto e distribuite, il che semplifica notevolmente il cablaggio, migliora l'integrazione del sistema e riduce i costi complessivi.

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

Good long-term stability: The physical e 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 e stability with small drift during long-term use.

Facile da ottenere il monitoraggio remoto: combinato con la tecnologia di comunicazione in fibra ottica, è facile ottenere il monitoraggio remoto in tempo reale e la trasmissione dei dati della pressione della condotta, il che è conveniente per la gestione centralizzata e la diagnosi dei guasti.

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, e water conservancy.

Examples of measurement objects of OFSCN® Sensore di Pressione per Condotte FBG:

Common measurement objects of OFSCN® Sensore di Pressione per Condotte FBG

The measurement objects of OFSCN® Sensore di Pressione per Condotte FBG 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:

Pressione del fluido nella condotta:

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

Pressione correlata alla struttura della condotta:

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, e 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 e 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.
Pressione correlata all'ambiente:

Pressione dell'acqua interstiziale: Nell'ingegneria civile, in particolare dighe, pendii, strutture sotterranee, ecc., il monitoraggio della pressione dell'acqua interstiziale nel suolo o nella massa rocciosa è cruciale per valutare la stabilità e potenziali disastri (come le frane).
Pressione geologica/pressione terrestre: Misurare la pressione del suolo o della roccia su condotte o strutture interrate aiuta a valutare l'impatto delle attività geologiche (come terremoti, subsidenza) sulle condotte.

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

Pressione diretta del mezzo: La pressione del gas o del liquido all'interno della condotta.

Pressione equivalente causata da forza o deformazione: Quando la condotta è soggetta a forze esterne (come carico del terreno, deformazione strutturale), il sensore riflette o deduce indirettamente la pressione che agisce sulla condotta misurando la deformazione del materiale della condotta.
