This article analyzes the advantages e application benefits brought by the small size of fiber bagg grating (FBG) sensors, including improved sensitivity, expanded usage environments, e convenience in engineering construction. It also introduces the production of the small-sized 'OFSCN® Capillary Seamless Steel Tube Series FBG Sensor' (also known as micro FBG probes or FBG sensors) by DCYS, which can be used for measuring various physical quantities such as temperature, strain, e stress in extreme environments. Partial physical images are provided.

1. Introduzione 1.alla struttura e al diametro dei sensori FBG di piccole dimensioni (sonde FBG)

Per la maggior parte dei sensori, le dimensioni ridotte sono un vantaggio significativo. Questo è principalmente dovuto al fatto che i sensori dovrebbero minimizzare i cambiamenti causati dal loro intervento nell'ambiente circostante o nell'oggetto misurato per ottenere misurazioni accurate.

The 'OFSCN® Capillary Seamless Steel Tube Series FBG Sensor (FBG sensor)' produced by DCYS is an extremely small FBG sensor (FBG thermometer, FBG strain gauge, FBG tensile gauge, etc.) that can be used to measure various physical quantities such as temperature, stress, e strain in extreme environments.

Figura 1

The typical 'OFSCN® Capillary Seamless Steel Tube Series FBG Sensor (FBG sensor)' consists of a stainless steel seamless tube and a fiber bragg grating (FBG) as the sensing element. Due to innovative patented technology and a minimalist structural design, our product differs significantly from traditionally packaged FBG sensors (see comparison in Figura 2).

Figura 2

The 'OFSCN® Capillary Seamless Steel Tube Series FBG Sensor (FBG sensor)' is much smaller in size than existing traditional FBG sensors, with a standard diameter of only 0.9mm (in addition to 2mm, 3mm diameter products, e a minimum diameter of 0.6mm).

Questa dimensione è inferiore ai sensori FBG comunemente visti 'incapsulati parzialmente in tubi di acciaio inossidabile' con un diametro generalmente di 6mm, e ancora più piccola dei sensori FBG incapsulati in tubi ceramici con un diametro generalmente di 10mm.

2. Application e construction advantages of small-sized 'OFSCN® Capillary Seamless Steel Tube Series FBG Sensor' (FBG probes)

The smaller size of the 'OFSCN® Capillary Seamless Steel Tube FBG Temperature Sensor' first increases its sensitivity. Increased sensitivity means more accurate temperature measurement e faster response. Consequently, the 'OFSCN® Capillary Seamless Steel Tube FBG Temperature Sensor' does not require thermal paste or various fillers inside (refer to references: 'Sensibilità dei Sensori di Temperatura FBG - Prospettiva della Risoluzione,' 'Sensibilità dei Sensori di Temperatura FBG - Prospettiva della Conduzione Termica,' 'Characteristics Analysis of OFSCN® Capillary Seamless Steel Tube FBG Temperature Sensors- High Sensitivity'.

The smaller size also greatly expands the application range of FBG sensors. Compared to Altro types of sensors, FBG sensors have the advantage of being small in size (previously, FBG sensors were often described with a diameter of 6mm). Now, with the 'OFSCN® Capillary Seamless Steel Tube FBG Sensor' having a diameter of only 0.9mm, many environments and objects that were previously limited by size can be tested using FBG sensors. After all, the smaller the grating sensor, the less it impacts the object being measured.

The smaller size also brings great convenience to the transportation e engineering construction of FBG sensors. Traditional FBG sensors are transported in bundles, while the 'OFSCN® Capillary Seamless Steel Tube FBG Sensor' is transported as a bundle. The benefits brought by this during engineering construction are evident e will be analyzed in subsequent articles.

Our philosophy is: 'OFSCN®, make optical fiber stronger!'
