Unlike traditional sensors, optical fiber with excellent physical, chemical, mechanical, and transmission performance, which make fiber optic sensor has the advantages of small volume, light weight, electromagnetic interference resistance, corrosion resistance, high sensitivity, wide measurement bandwidth, testing electronic devices and sensors can be far away, and and can constitute a sensor network.
The advantages of optical fiber sensors are as follows:
1, High accuracy, fast response speed, wide linear characteristic range, good repeatability and high signal-to-noise ratio of detection signal. Due to the mass production and low price of optical fiber, it can be widely used now.
2, Optical fiber is made of dielectric material quartz, and it is transmitted by optical signal. Therefore, it is safe, reliable, and strong in electromagnetic interference. It can adapt to environmental conditions such as electricity, oil, chemical industry, metallurgy and other inflammable, explosive or toxic environment.
3, Anti corrosion, strong anti pollution ability, can be used in place with greater temperature difference, good time and time aging characteristics, long working life.
4, Small in size, light in weight, easy to install, and strong in adaptability to the environment in which the object is measured.
5. Optical fiber sensor is a passive device, its own independence is good, and it will not destroy the state of measurement.
