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. Hata hivyo, for certain special industrial environments (kama vile kuwaka na kulipuka, voltage ya juu, mkondo wa juu, kuingiliwa kwa nguvu ya sumakuumeme, nk.), temperature sensors based on electrical signals are usually greatly limited in terms of safety and signal stability. Kwa hiyo, 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. Wakati huo huo, 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 kipimo cha joto la optic iliyosambazwa

After more than ten years of development, fiber optic iliyosambazwa 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, na vituo vya data, due to their advantages of long measurement distance, usahihi wa juu, no measurement blind spots, na upinzani mkubwa kwa kuingiliwa kwa sumakuumeme. 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. Kwa hiyo, its spatial resolution and temperature measurement accuracy are important characterization parameters.

Katika miaka ya hivi karibuni, 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, na leakage detection of oil pipelines.

The mfumo wa kipimo cha joto cha fiber optic iliyosambazwa can monitor the temperature of the measured object in real time. Haiwezi tu kuchunguza tukio la matukio ya moto kwa wakati halisi, 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 mfumo wa kipimo cha joto cha fiber optic iliyosambazwa inatumiwa sana na makampuni mengi makubwa ya ujenzi na subway, kupunguza kwa kiasi kikubwa matukio ya ajali mbalimbali za moto. Aidha, 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.
