FBG Sensing Technology for SHM of Buildings, Pipelines, and Large Industrial Equipment in Industrial Automation Industry
Structural health monitoring(short for SHM) has become increasingly important in the industrial automation industry, especially in applications such as buildings, pipelines, and large industrial equipment. The ability to monitor the condition of these structures can help prevent accidents and improve overall efficiency. Fiber grating sensing technology has emerged as a highly effective means of detecting changes in temperature, strain, and other physical quantities in these applications. 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 SHM of buildings, pipelines, and large industries Equipment in the industrial automation industry.
Fiber Bragg Grating Sensing Principle：
Fiber Bragg gratings (FBGs) are periodic structures that are inscribed in the core of an optical fiber. These structures reflect a specific wavelength of light that is determined by the periodicity of the grating. When the grating is subjected to mechanical or thermal strain, the reflected wavelength changes in a predictable manner. By monitoring the reflected wavelength, changes in strain, temperature, and other parameters can be detected. FBG sensors can be used to monitor a wide range of parameters, including strain, stress, temperature, and vibration.

Why SHM is Required for Buildings, Pipelines, and Large Industrial Equipment:
Structural health monitoring is required in the industrial automation industry to detect changes in the condition of buildings, pipelines, and large industrial equipment. These structures are subject to various environmental and operational conditions that can cause wear and tear, corrosion, or other damage. Detecting these changes early can prevent accidents, reduce downtime, and improve overall efficiency.
Difficulties in SHM of Buildings, Pipelines, and Large Industrial Equipment:
Structural health monitoring of buildings, pipelines, and large industrial equipment presents several challenges. These structures are often large and complex, making it difficult to monitor all critical points. Traditional monitoring methods such as strain gauges and thermocouples can be cumbersome and require a lot of wiring. Additionally, these methods are often limited in terms of sensitivity and speed of response.
What Problems Can be Solved by FBG Sensing Technology:
Fiber grating sensing technology can help solve some of the problems associated with structural health monitoring in the industrial automation industry. FBG sensors are small, lightweight, and can be easily distributed throughout a structure, making it possible to monitor all critical points. The sensors are also highly sensitive and can detect changes in temperature, strain, and other physical quantities with high accuracy and speed. Furthermore, FBG sensors are immune to electromagnetic interference, making them suitable for use in harsh environments.

The 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.
