Ang labing kaayo nga tiggama sa fiber optic grating temperature sensors

In the current situation of power equipment, such as transformer temperature measurement, electrical sensors (such as platinum resistors) are mainly used. One wire is connected to one sensor, and the signal is an electrical signal, which is easily affected by strong electricity and strong magnetism. It is also limited to use in flammable, explosive and other situations; In power applications with strong electromagnetic interference and high insulation requirements, FJINNO’s independently developed fiber optic temperature measurement system has been widely used in various temperature measurement fields.

What are the advantages of fiber optic grating sensors

As a type of passive fiber optic device, fiber Bragg gratings have advantages such as resistance to electromagnetic interference, taas nga temperatura, and small size. Fiber Bragg grating sensors mainly use fiber Bragg gratings, and the sensor signal made of fiber Bragg gratings is wavelength modulated, with strong anti-interference ability. The measurement signal is not affected by factors such as fiber loss, light source fluctuations, and detector aging. It is easy to combine wavelength division multiplexing technology to form a fiber Bragg grating sensing network, achieving distributed multi-point real-time online sensing. It is widely used in the measurement of physical quantities such as temperature, strain, and pressure. Temperature measurement is one of the most important applications of fiber optic grating sensors. Electronic temperature sensors such as thermocouple sensors and thermistor sensors have disadvantages such as poor resistance to electromagnetic interference, dili maayo nga kalig-on, and slow response speed. They are suitable for narrow environments and cannot be used in harsh environments. Fiber optic grating temperature sensors have advantages such as high sensitivity, gamay nga size, resistance to electromagnetic radiation, strong stability, and long signal transmission distance, making them suitable for a wide range of environments.

What are the characteristics of fiber optic grating temperature sensors

Fiber Bragg Grating Temperature Sensor is a sensor that detects temperature by the central wavelength shift of the reflected light signal from the internal sensitive elementthe fiber Bragg grating. Installation structures with different packaging options such as surface, gisukip, ug pagpaunlod. Tungod sa kamatuoran nga ang fiber optic grating temperatura sensors sa paggamit sa kahayag balud sa pagpadala sa impormasyon, ug ang mga optical fiber kay electrically insulated ug corrosion-resistant transmission media, they are not afraid of strong electromagnetic interference and do not affect the external electromagnetic field. Kini naghimo kanila nga sayon ​​​​ug epektibo alang sa pag-monitor sa nagkalain-laing dako nga electromechanical, petrochemical, taas nga presyur sa metalurhiko, kusog nga electromagnetic interference, masunog, eksplosibo, ug hilabihan ka makadaot nga mga palibot, nga adunay taas nga kasaligan ug kalig-on. Dugang pa, the measurement results of fiber optic grating temperature sensors have good repeatability, making it easy to form various forms of fiber optic sensing networks and can be used for absolute measurement of external parameters. Multiple gratings can also be written into a single optical fiber to form a sensing array, pagkab-ot sa quasi-apod-apod nga pagsukod.

Fiber optic grating sensors not only have the advantages of ordinary fiber optic sensors, such as electromagnetic resistance, pagsukol sa corrosion, high temperature resistance, no electricity, no heat generation, flame resistance, explosion-proof, gaan nga timbang, gamay nga volume, and safe operation in harmful or dangerous environments, but also have unique advantages: fiber optic sensors are easy to couple and have low coupling loss; Strong anti-interference ability, integrating sensing and transmission, and having stronger multiplexing ability, making it easy to form a sensing network; It has a wide range of measurement objects and is easy to achieve multi parameter sensing measurement.

Application Fields of Fiber Bragg Grating Sensors

Fiber optic grating sensors have various installation methods, such as surface mounted and embedded, and can be widely used for distributed temperature monitoring and measurement of civil engineering structures such as bridges, mga dam, tunnels, as well as quasi distributed accurate temperature measurement of large facilities or equipment in the fields of chemical, gahum, military, aerospace, fire protection, mining, ug uban pa. They can also be used for temperature sensing fire detection and automatic alarm in oil tanks and highway tunnels.
