광섬유 브래그 격자(FBG) 센서 직경 - 모세관 - 소량 - 0.6mm, 일반 크기 0.9mm FBG 센서
This article analyzes the advantages 및 application benefits brought by the small size of fiber bagg grating (FBG) sensors, including improved sensitivity, expanded usage environments, 및 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, 및 stress in extreme environments. Partial physical images are provided.
1. 소형 FBG 센서 (FBG 프로브)의 구조 및 직경 소개
대부분의 센서에서 작은 크기는 중요한 장점입니다. 이는 주로 센서가 정확한 측정을 달성하기 위해 주변 환경 또는 측정 대상에 대한 개입으로 인한 변화를 최소화해야 하기 때문입니다.
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, 및 strain in extreme environments.

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 그림 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, 및 a minimum diameter of 0.6mm).
이 크기는 일반적으로 직경 6mm인 '부분적으로 스테인리스 스틸 튜브 패키지' FBG 센서보다 작고, 일반적으로 직경 10mm인 세라믹 튜브 패키지 FBG 센서보다도 작습니다.

2. Application 및 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 및 faster response. Consequently, the 'OFSCN® Capillary Seamless Steel Tube FBG Temperature Sensor' does not require thermal paste or various fillers inside (refer to references: FBG 온도 센서의 감도 - 해상도 관점, FBG 온도 센서의 감도 - 열전도 관점, '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 기타 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 및 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 및 will be analyzed in subsequent articles.
Our philosophy is: 'OFSCN®, make optical fiber stronger!'
