Medidor de deformación de barras de refuerzo con red de Bragg en fibra (FBG) - Medidor de fuerza de tracción de barras de refuerzo FBG

Principio del medidor de deformación de barras de refuerzo con red de Bragg en fibra:

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 y length changes, indirectly indicating the stress y tension experienced by the rebar, given the known elastic modulus of the rebar.

Estructura y composición del sistema del medidor de deformación de barras de refuerzo FBG:

OFSCN® Micro FBG Rebar Strain Gauge consists of fiber connectors, all-metal stainless steel seamless tubes/polymer elastic materials, y FBG encapsulation. When combined with a fiber Bragg grating demodulator, it forms a FBG rebar sensing detection system.

Métodos de despliegue para el medidor de deformación de barras de refuerzo FBG:

OFSCN® Micro FBG Rebar Strain Gauge can be directly fixed y 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.

Entorno operativo e industrias de aplicación para el medidor de deformación de barras de refuerzo FBG:

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, y 40mm rebars. It can also be used for real-time online monitoring during the use of rebars of various sizes.

Sus aplicaciones cubren todas las industrias que utilizan barras de refuerzo en la vida diaria, como presas, puentes, túneles, superficies e interiores de edificios, superficies e interiores de hormigón armado, terraplenes de carreteras, túneles y más.

Ventajas del medidor de deformación de barras de refuerzo FBG:

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, y displacement. It is not affected by environmental conditions such as haze, rain, snow, or obstructions. The measurements are accurate y 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 y sensing. Therefore, it is not susceptible to electromagnetic interference y can work in various strong y 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 y cover a wide range of rebar, thereby saving the number y cost of sensors y rebar gauges.

OFSCN® Micro FBG Rebar Strain Gauge is a digital, recordable, y 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, y multiple targets. It has a wide spatial coverage range.
