Extensômetro de Barra de Aço FBG (Grade de Bragg em Fibra) - Medidor de Força de Tração FBG para Barra de Aço

Princípio do Extensômetro de Barra de Aço FBG:

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

Estrutura e Composição do Sistema do Extensômetro de Barra de Aço FBG:

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

Métodos de Implantação do Extensômetro de Barra de Aço FBG:

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

Ambiente Operacional e Indústrias de Aplicação do Extensômetro de Barra de Aço 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, e 40mm rebars. It can also be used for real-time online monitoring during the use of rebars of various sizes.

Suas aplicações abrangem todas as indústrias que usam barras de aço no dia a dia, como barragens, pontes, túneis, superfícies e interiores de edifícios, superfícies e interiores de concreto armado, leitos de rodovias, túneis e muito mais.

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

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