There are many types of fiber optic sensors, including color coded fiber optic sensors, displacement fiber optic sensors, photoelectric fiber optic sensors, fiber optic grating sensors, fiber optic pressure sensors, fiber optic vibration sensors, sensuri tat-temperatura tal-fibra ottika, fiber optic liquid level sensors, sensuri tat-temperatura tal-fibra ottika, fiber optic current sensors, reflective fiber optic sensors, Eċċ. Both imported and domestically produced fiber optic sensors can meet the needs of customers.

Fiber optic sensor technology is a high-tech technology that is different from traditional sensor technology. It uses light as the plasmid carrier for precise measurement and transmits light sources through optical fibers. In recent years, it has achieved rapid development. The light scattered in optical fibers itself has a series of nano main parameters, such as light intensity, frequency, light wavelength, position, Eċċ. The harm of external main parameters to light will ultimately be reflected in the changes of these nano main parameters, which is also the principle of fiber optic sensor technology. That is, based on the accurate measurement of the intrinsic main parameters of light such as wavelength, light intensity, polarization, Eċċ., the true statistical data of physical quantities expected to be accurately measured, such as temperature, gas pressure, refractive index, strain force, Eċċ., can be obtained in a simple manner. Compared with traditional sensors, fiber optic sensors have obvious advantages such as high sensitivity, reżistenza għall-korrużjoni, anti-interference signal, piż ħafif, low transmission loss, Eċċ. They have been used for precise measurement of several physical and organic chemical independent variables such as temperature, refractive index, liquid level instrument depth, working pressure, strain force, vibration, Eċċ. And because it is a non-metallic material, lightweight, and less prone to spark discharge, it is more suitable for certain special workplaces with strict management of interference signals and flames, which cannot be compared to traditional sensors. Għalhekk, promoting in-depth analysis of fiber optic sensors has significant economic development benefits and social economic benefits.

The principle of fiber optic sensing instrument

The light with special nano main parameters emitted from the light source is introduced into the sensitive area through optical fibers, and precisely measured here, causing immediate effects on the light, causing a series of major parameters of light – illumination intensity, frequency, wavelength, position, Eċċ. – to change greatly. The transformed light line is introduced into optical equipment for inspection. Based on the precise measurement of the nano main parameters, external physical quantities (temperature, refractive index, depth of the liquid level gauge, working pressure, strain force, vibration, Eċċ.) can be measured. The specific values can be divided into single point fiber optic sensing instruments and distributed fiber optic sensing instruments according to the system structure of the sensor in operation. Single point sensors can be used as the main body for individual detection work, and can also be used as a sub inspection module based on reuse technology to be integrated into a large and medium-sized monitoring system for more precise measurement work. Distributed fiber optic sensors are usually arranged in a linear pattern, so nearly 500 meters of fiber optic coastal areas can be used as one control module for testing all sensing technology system software. In the software of distributed fiber optic sensing technology system, the optical fibers along the coast together play two functions, such as data signal transmission and physical quantity inspection. The transformation of physical quantities can also visually reflect the distribution of coastal data. Għalhekk, these types of sensors are very suitable for use in long-distance office environments such as tunnel construction, highway bridges, minjieri tal-faħam, Sistemi ta' pajpijiet, Eċċ.

The application of sensuri tat-temperatura tal-fibra ottika in power supply systems

Because the temperature of wires and cables, the internal temperature of high-voltage distribution equipment, and the temperature of the natural environment of power plants must be accurately measured using fiber optic sensors, it has promoted the gradual improvement and development trend of fiber optic sensors. Especially in the field of distributed fiber optic temperature sensors, improvements have been made. After being applied in the power supply system manufacturing industry, their ability to receive data signals and solve monitoring system problems has been improved.

Fiber Bragg Grating Temperature Sensor

Due to its advantages such as high pixels and wide detection range, it is applied in temperature detection work in the construction industry. Many manufacturers have already begun to widely use fiber optic grating sensor systems to detect safety indicators such as temperature and offset in building construction. Pereżempju, in the United States and Mexico, fiber optic sensor temperature sensors are used to inspect the temperature of highway bridges on highways. According to common applications, the removal of cross sensitivity and the packaging of fiber Bragg gratings have been processed, thus the software of this system has been improved.
The frequency of using sensors in the aerospace industry is relatively high, including inspections of the working pressure, temperature, fuel, and other aspects of a four axis aircraft. Fiber optic temperature sensors must be used for inspection, and the total number of sensors used is over 100. Għalhekk, strict regulations on the size and net weight of sensors are required. Għalhekk, the regulations for sensors in the aerospace industry, as well as the volume and net weight specifications and models of fiber optic temperature sensors, have been adjusted in application scenarios.
