What are the advantages of using optical fibers for temperature measurement
Temperature is a very important physical quantity in engineering technology and scientific research, therefore temperature measurement technology has been continuously studied and developed. Traditional temperature measurement often uses temperature sensors such as thermistors and optical pyrometers. Nanging, for certain special industrial environments (such as flammable and explosive, high voltage, saiki dhuwur, strong electromagnetic interference, lsp.), temperature sensors based on electrical signals are usually greatly limited in terms of safety and signal stability. Mulane, in order to achieve safe and effective temperature measurement in various situations, the development of new temperature measurement systems has become an inevitable trend. The advantages of optical fiber such as electrical insulation, geometric variability, and inherent large signal transmission bandwidth, as well as the development of grating sensors, have enabled optical fiber temperature sensors to break through the limitations of traditional temperature sensors and provide very effective means for temperature measurement in harsh environments such as strong electromagnetic interference. Ing wektu sing padha, optical fiber temperature measurement systems can overcome the limitations of traditional point sensors and measure temperature field information distributed along the optical fiber.
The characteristics of pangukuran suhu serat optik sing disebarake
After more than ten years of development, distributed fiber optic temperature measurement systems have been widely used in fields that require temperature measurement, fire alarm, and energy conservation and emission reduction, such as power cable tunnels, comprehensive pipe galleries, coal industry, and data centers, due to their advantages of long measurement distance, akurasi dhuwur, no measurement blind spots, and strong resistance to electromagnetic interference. Based on Raman DTS (Distributed Fiber Temperature Measurement System), temperature information is obtained by comparing the intensity of Stokes light and anti Stokes light.
The working principle of distributed fiber optic temperature measurement
The distributed fiber optic temperature measurement device is made using the spontaneous Raman scattering effect. Its anti Stokes signal is temperature sensitive, while the Stokes signal is temperature insensitive. The temperature values at each point along the fiber optic can be calculated using its ratio of light intensity, and precise positioning can be achieved using its Rayleigh scattering technology. Mulane, its spatial resolution and temperature measurement accuracy are important characterization parameters.
In recent years, distributed fiber temperature sensing (DTS) systems based on Raman scattering have been extensively studied and developed. Due to its resistance to electromagnetic interference and long measurement distance, distributed fiber optic temperature measurement is widely used in many industrial fields, such as fire warning, wire safety monitoring, lan leakage detection of oil pipelines.
Ing sistem pangukuran suhu serat optik terdistribusi can monitor the temperature of the measured object in real time. It can not only detect the occurrence of fire events in real time, but also provide accurate fire locations, buying time for immediate firefighting and minimizing accident losses. FJINNO’s distributed fiber optic temperature measurement system eliminates the safety hazards of traditional temperature monitoring systems and greatly improves the availability of monitoring systems for temperature monitoring of temperature objects. The distributed fiber optic temperature measurement system is widely used by many large construction and subway companies, greatly reducing the occurrence of various fire accidents. Kajaba iku, distributed fiber optic temperature measurement systems also have important and extensive application prospects in fields such as geothermal development and application, oil and gas extraction, and chemical production.
