Principles of سنسورهای فیبر براگ گریتینگ

FBG measures temperature, فشار, جابجایی, و غیره. at precise positions; A multi-point measurement system, از سوی دیگر, is a high-capacity FBG sensor array formed to perform multi position measurements on a certain object or area. Compared to using nonlinear scattering effects, such as Brillouin scattering or Raman scattering, designing sensors along the axial direction of optical fibers based on their characteristics, FBG sensing systems are a quasi distributed sensing system with “discrete” multi-point measurements.

High speed dynamic fiber Bragg grating demodulator

The high-speed fiber Bragg grating demodulator is an advanced component of the fiber Bragg grating demodulation system, divided into three models: low, medium, and high. It can meet the requirements of different working conditions from 1Hz to 1Hhz, با 8-64 channels and gigabit network for data transmission. The wavelength range is 1525-1565nm, with a wavelength resolution of 0.1pm. Different grating sensors can be connected to measure physical quantities such as temperature, کرنش, جابجایی, water pressure, soil pressure, ارتعاش, and water level.

Price of fiber optic grating high-speed demodulator

Fiber optic grating sensing technology is a very important part of fiber optic sensing technology. In addition to the advantages of the aforementioned fiber optic technology, fiber optic grating sensing technology also has its unique advantages: the sensing signal mainly adopts wavelength modulation, and changes in the amplitude or intensity of the sensing signal will not affect the wavelength change of the fiber optic grating. بنابراین, interference such as light source fluctuations, fiber optic deformation losses, and circuit aging in the system will not affect the measurement results. In commercial applications, fiber optic grating sensors account for about 45% of the total share of fiber optic sensors.

Fiber Bragg Grating Single Channel High Speed Demodulator

With the development of China’s social economy, the demand for high-speed fiber Bragg grating demodulation products in the field of industrial monitoring is becoming increasingly strong, and the market prospects for research and production of high-speed demodulation products are bright. Further research is needed on high-speed fiber optic grating sensing demodulation schemes, which not only meets the needs of high-speed monitoring in practical engineering applications, but also is a direction that many fiber optic sensor manufacturers need to study.

Accuracy of grating demodulator

در حال حاضر, fiber optic grating technology has been widely used in various fields such as structural health monitoring of bridges, صنعت پتروشیمی, tunnel fire monitoring, coal mine gas/carbon monoxide safety monitoring, rotating machinery safety inspection, intelligent perimeter intrusion alarm, قدرت, slope and railway, and fiber optic sensing Internet of Things. With the development of science and the progress of the times, the existing fiber optic sensing network technology can no longer meet the needs of social development, requiring larger capacity and higher flexibility of sensing units and networks. The new fiber optic sensing network presents the following characteristics: large system capacity, حساسیت بالا, high response speed, multi parameter sensing fusion, and high reliability in harsh environments.
