1. 高引張光ファイバーブラッググレーティングセンサー（FBGセンサー、FBGプローブ）の構造と利点

引張性能が、FBGセンサー（FBGプローブ）のエンジニアリング建設および長期的な通常使用に影響を与えることは明らかです。以下では、引張能力の観点から簡単に分析します。

The body of OFSCN® Capillary Seamless Steel Tube Series Fiber Bragg Grating Sensors (FBG sensors, FBG probes) is made of stainless steel, benefiting from the characteristics of this material. Therefore, they possess high tensile strength.

2. Tensile Strength of OFSCN® Capillary Seamless Steel Tube Series Fiber Bragg Grating Sensors (FBG sensors, FBG probes)

The main body of the standard OFSCN® Capillary Seamless Steel Tube Fiber Bragg Grating Sensors (FBG sensors, FBG probes) has an outer diameter of 0.9 millimeters and a wall thickness of 0.18 millimeters (see 図1 and 2). Based on our calculations and measurements, the main body of the grating sensor can withstand a tensile force exceeding 650 Newtons. We have determined a safe tensile strength of over 400 Newtons for practical use, which, in simpler terms, is equivalent to lifting a weight of 40 kilograms using this sensor.

The tensile strength of the grating sensor can be adjusted by modifying the diameter and wall thickness of the stainless steel seamless tube in OFSCN® Capillary® Seamless Steel Tube Series FBG Stress Sensors (FBG tensile gauges, FBG pressure gauges) and Strain Sensors (FBG strain gauges) (see 図3 and 4). Additionally, the tensile strength of the grating sensor can be adjusted by nesting multiple layers of steel tubes and other structural elements (see Figure 5 and 6).

By using larger diameter そして thicker-walled stainless steel seamless tubes, OFSCN can provide grating sensors with a tensile strength exceeding 10,000 Newtons (yes, the '0' is correct, そして it can have even more digits if required).

3. Applications そして Construction Advantages of OFSCN® Capillary Seamless Steel Tube Series Fiber Bragg Grating Sensors (FBG sensors, FBG probes) with High Tensile Strength

DCYS produces 'OFSCN® Capillary Seamless Steel Tube Series FBG Sensors' using a unique patented structure, which exhibits higher strength compared to traditional FBG sensors.

Although the optical fiber cable of traditional FBG sensors has relatively good tensile strength, the connection between the stainless steel tube そして the optical fiber cable is the weakest part of the entire grating sensor. This vulnerability can be compared to the shortest plank in the well-known 'barrel theory,' greatly reducing the overall tensile strength. Unfortunately, we cannot provide specific numerical values as DCYS has not conducted relevant tests.

The high tensile strength of OFSCN® Capillary Seamless Steel Tube FBG Sensors primarily manifests as advantages in engineering construction. The high tensile strength directly reduces the difficulty そして losses in construction for contractors, thus lowering the installation cost of the sensors.

In the past, the installation そして deployment of traditional fiber optic grating sensors were considered cumbersome そして required skilled workers with years of experience to handle them carefully. However, with the higher tensile strength of OFSCN® Capillary Seamless Steel Tube FBG Sensors, ordinary workers can now participate in the construction as long as they meet the minimum bending radius requirements of the sensors. The sensors are less prone to damage.

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