The principle of fiber optic sensing instrument-INNO

There are many types of fiber optic sensors, including color coded fiber optic sensors, displacement fiber optic sensors, photoelectric fiber optic sensors, capteurs à réseaux de fibres optiques, fiber optic pressure sensors, fiber optic vibration sensors, capteurs de température à fibre optique, fiber optic liquid level sensors, capteurs de température à fibre optique, fiber optic current sensors, reflective fiber optic sensors, etc.. 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. Au cours des dernières années, it has achieved rapid development. The light scattered in optical fibers itself has a series of nano main parameters, comme l'intensité lumineuse, fréquence, light wavelength, position, etc.. Les dommages causés à la lumière par les principaux paramètres externes se refléteront finalement dans les modifications de ces nanoparamètres principaux., qui est également le principe de la technologie des capteurs à fibre optique. C'est, basé sur la mesure précise des principaux paramètres intrinsèques de la lumière tels que la longueur d'onde, intensité lumineuse, polarisation, etc., les véritables données statistiques des grandeurs physiques censées être mesurées avec précision, comme la température, gas pressure, indice de réfraction, force de déformation, etc., peut être obtenu de manière simple. Compared with traditional sensors, les capteurs à fibre optique présentent des avantages évidents tels qu'une sensibilité élevée, résistance à la corrosion, signal anti-interférence, poids léger, low transmission loss, etc.. Ils ont été utilisés pour mesurer avec précision plusieurs variables indépendantes physiques et chimiques organiques telles que la température., indice de réfraction, profondeur de l'instrument de niveau de liquide, pression de travail, force de déformation, vibration, etc.. Et parce que c'est un matériau non métallique, léger, et moins sujet aux décharges d'étincelles, it is more suitable for certain special workplaces with strict management of interference signals and flames, which cannot be compared to traditional sensors. Donc, promoting in-depth analysis of fiber optic sensors has significant economic development benefits and social economic benefits.

Le principe de l'instrument de détection à fibre optique

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, fréquence, longueur d'onde, position, etc.. – 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 (température, indice de réfraction, depth of the liquid level gauge, pression de travail, force de déformation, vibration, etc.) can be measured. The specific values can be divided into single point fiber optic sensing instruments and fibre optique distribuée 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. Donc, these types of sensors are very suitable for use in long-distance office environments such as tunnel construction, highway bridges, mines de charbon, pipelines, etc..

L'application de capteurs de température à fibre optique 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 température distribuée de la fibre optique capteurs, 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.

Capteur de température à réseau de Bragg en fibre

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. Par exemple, 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, température, 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. Donc, strict regulations on the size and net weight of sensors are required. Donc, 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.
