FBG Sensing Technology for Strain Monitoring in the Aerospace Industry
Fiber Bragg grating sensing technology is widely used in various industries, for its advantages of high precision, high sensitivity and high reliability. In the aerospace industry where safety and reliability are critical, Beijing Dacheng Yongsheng Technology Co., Ltd.'s fiber grating sensing technology is becoming more and more important for structural health monitoring. Strain monitoring is an important aspect of this technology as it provides information on the mechanical deformation of components and structures under different operating conditions. In this article, we will discuss the problems that fiber grating sensing technology can solve，and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can support the strain monitoring in aerospace industry.
Fiber Bragg Grating Sensing Principle:
Fiber Bragg grating (FBG) sensors are the most commonly used fiber grating sensors for SHM in the aerospace industry. An FBG is a microscopic optical device embedded in an optical fiber that reflects a specific wavelength of light. When an FBG is subjected to strain or temperature changes, the reflected wavelength changes, which can be measured and used to calculate the magnitude of the strain or temperature.

Challenges in Strain Monitoring in the Aerospace Industry:
The aerospace industry poses several challenges for strain monitoring, including harsh operating conditions, limited space, and weight restrictions. The components and structures used in aerospace applications are subject to extreme temperatures, pressure, and vibrations, which can cause damage or failure over time. Strain monitoring is critical to detecting and preventing these failures, but it can be difficult to implement in the limited space available within aircraft and spacecraft.
What Strain Detection Problems Can FBG Sensing Technology Solve：
DCYS's Fiber grating sensing technology can provide accurate and reliable strain measurements in real-time, making it ideal for structural health monitoring in aerospace applications. It can detect small changes in strain and deformation, which may indicate the development of structural damage or failure. This can help prevent catastrophic accidents and reduce maintenance costs.
Recommended fiber grating strain sensors:
This product is a high-range fiber bragg grating strain sensor (FBG strain gauge) used for strain measurement. It can be used in a single-ended structure, where it is inserted into the object to be measured for strain measurement. It can also be used in a double-ended structure, where it is fixed with a fixture or bonded directly to the surface for strain measurement, enabling multi-point strain measurement when connected in series. The structure of this product is the same as that of fiber bragg grating stress sensors.
Product Overview:
The OFSCN® high-range fiber bragg grating strain sensor (FBG strain gauge) consists of fiber connectors (FC, SC, LC, ST, etc.), high elastic materials, and single-point FBG encapsulation. Depending on the materials used, it can work at room temperature or a maximum high temperature of 120 degrees Celsius (customizable upon request).
This product is characterized by its small size, light weight, high tensile and compressive strength, waterproof and moisture-proof properties, and full sealing. By utilizing the strain characteristics of FBG, this sensor can be inserted, welded, bonded, or adhered to the internal or surface of the test structure for strain detection and monitoring.
2500με Fiber Bragg Grating Strain Sensor - FBG Strain Gauge - Metal Encapsulation - High Temperature FBG Strain SensorThe product is a fiber Bragg grating strain sensor (FBG strain gauge) encapsulated in seamless steel tube, used for strain measurement. In most cases, it is a single-point single-ended structure, or it can be produced as a multi-point single-ended structure. In a few cases, it can also be a double-ended structure. The deployment method of the product depends on the supporting fixtures, which can be directly inserted into the test object, or installed by surface welding with corresponding fixtures, bolted with drilled holes for fixation, adhesive surface mounting, tied with straps for fixation, or fixed with clamps, among various installation methods. This product is a basic structural product, which can be calibrated as a FBG displacement sensor, or used as a FBG stress sensor.
