Product Alias: Fiber Bragg Grating Rebar Strain Gauge, FBG Smart Rebar, Rebar Strain Gauge, Rebar Deformation Sensor, Rebar Tensile Force Gauge, Rebar Monitor.
Product Function: Monitors strain, deformation, stress, applied tension, and ultimate tensile strength for various types of rebars.
Principle of Fiber Bragg Grating Rebar Strain Gauge:
OFSCN® Micro Fiber Bragg Grating Rebar Strain Gauge is an application of DCYS's FBG strain sensors. The strain of the rebar reflects its deformation and length changes, indirectly indicating the stress and tension experienced by the rebar, given the known elastic modulus of the rebar.
Structure and System Composition of FBG Rebar Strain Gauge:
OFSCN® Micro FBG Rebar Strain Gauge consists of fiber connectors, all-metal stainless steel seamless tubes/polymer elastic materials, and FBG encapsulation. When combined with a fiber Bragg grating demodulator, it forms a FBG rebar sensing detection system.
Deployment Methods for FBG Rebar Strain Gauge:
OFSCN® Micro FBG Rebar Strain Gauge can be directly fixed and installed with clamps on both ends, welded, bundled, or directly installed on the surface of the rebar... In certain special applications, specially designed fixtures can be used to assist in the deployment of smart rebar gauges.
Operating Environment and Application Industries for FBG Rebar Strain Gauge:
OFSCN® Micro FBG Displacement Sensor is commonly used in various pre-use inspections of rebars of different sizes, such as φ12, 16, 18, 20, 22, 25, 28, 32, 36, and 40mm rebars. It can also be used for real-time online monitoring during the use of rebars of various sizes.
Its applications cover all industries that use rebars in daily life, such as dams, bridges, tunnels, building surfaces and interiors, reinforced concrete surfaces and interiors, highway roadbeds, tunnels, and more.

Advantages of FBG Rebar Strain Gauge:
Compared to rebar gauges based on steel strings or vibrating wires, OFSCN® Micro FBG Rebar Strain Gauge uses the measurement of the FBG inside the sensor as the standard for detecting rebar strain, stress, tension, and displacement. It is not affected by environmental conditions such as haze, rain, snow, or obstructions. The measurements are accurate and the response is fast (millisecond-level response).
Compared to various electrical signal rebar gauges based on steel strings or vibrating wires, OFSCN® Micro FBG Rebar Strain Gauge is based on optical fiber communication and sensing. Therefore, it is not susceptible to electromagnetic interference and can work in various strong and weak electromagnetic environments.
In addition, the length of OFSCN® Micro FBG Rebar Strain Gauge can be customized. It can be used for short-length sampling measurements of rebar, as well as long-length overall measurements of rebar. It can monitor large strain values and cover a wide range of rebar, thereby saving the number and cost of sensors and rebar gauges.
OFSCN® Micro FBG Rebar Strain Gauge is a digital, recordable, and network-enabled sensor. It can be integrated into a FBG smart rebar sensing system, capable of monitoring various rebar information in large-scale buildings with large spaces, long distances, and multiple targets. It has a wide spatial coverage range.
