Sensor ya halijoto ya fiber optic kwa minus 200 degrees Celsius-INNO

The use of fiber optic temperature measurement technology for temperature monitoring in sub zero low temperature environments has many unique advantages. Chini, the advantages of fiber optic temperature measurement in low-temperature monitoring will be elaborated in detail from the aspects of stability, usahihi, usalama, nk

Utulivu mzuri, able to withstand extremely low temperature environments

Conventional electronic temperature sensors exhibit a sharp decline in performance or even fail at extremely low temperatures, while fiber optic temperature measurement is not affected by temperature. The fiber optic temperature measurement system uses quartz fiber optic as the sensor, and the melting point of quartz material is as high as 1700 ℃. Even in ultra-low temperature environments of -200 ℃, sensor ya fiber optic bado inaweza kudumisha operesheni thabiti bila uharibifu wa utendaji. Hii huwezesha mfumo wa kipimo cha joto la nyuzi macho kutumika kwa njia ya kuaminika katika hali ya halijoto ya chini sana kama vile nitrojeni kioevu., oksijeni ya kioevu, na heliamu ya kioevu, na vile vile katika maeneo kama vile ghala za joto la chini na vifaa vya mnyororo wa baridi.

Usahihi wa juu na azimio bora la joto

The mfumo wa kipimo cha joto la fiber optic hutumia kanuni ya mwanga baada ya mwanga wa mwanga wa umeme kukokotoa halijoto ya mazingira ambamo optic ya nyuzinyuzi iko kwa kuchanganua badiliko la papo hapo la muda wa optic ya nyuzi za umeme.. Kanuni hii ya kipimo cha halijoto huamua kuwa ina usahihi wa juu sana wa kipimo na azimio la halijoto, and has obvious advantages compared to traditional temperature measurement components such as platinum resistors and thermocouples. High precision temperature measurement data can provide reliable basis for precise control of low-temperature environments.

Usalama wa ndani, non electric and passive
The fiber optic itself is an electrical insulator. In the process of fiber optic temperature measurement, the fiber optic sensor does not contain any electronic components, and there is no current generation or flow. This inherent safety feature enables fiber optic temperature measurement systems to be safely applied in flammable and explosive environments, such as low temperature environments such as oil, gesi asilia, migodi ya makaa ya mawe, nk. Wakati huo huo, due to the absence of source devices, fiber optic sensors do not require separate power supply, eliminating the worry of power failure and greatly improving system reliability.

Kuingilia kati kwa sumakuumeme, more reliable measurement results
In a strong electric field environment, electronic temperature sensors are susceptible to electromagnetic interference, resulting in a decrease in temperature measurement accuracy. Fiber optic is completely unaffected by electromagnetic fields, and optical signals are not contaminated or attenuated. Kwa hiyo, the measurement results of the fiber optic temperature measurement system are more accurate and reliable, making it very suitable for temperature monitoring in low-temperature areas with strong electromagnetic environments such as substations and power plants.

Ukubwa mdogo, uzito mwepesi, flexible installation and use
Fiber optic sensors have a small diameter, uzito mwepesi, kubadilika nzuri, and can be bent freely, making installation very convenient. It has a small thermal contact area with the low-temperature tested object, small thermal inertia, na kasi ya majibu ya haraka. The characteristics of small size and light weight also make it easier to integrate fiber optic temperature measurement systems into various low-temperature equipment and devices.

Long lifespan with less maintenance, reducing usage costs
The fiber optic sensor is made of high-purity quartz glass, which has no mechanical wear and a long working life. Its optical performance has undergone strict screening and aging experiments, and its long-term stability is good. Fiber optic cables have strong corrosion resistance, upinzani wa voltage ya juu, and tensile resistance, and can maintain performance under various harsh working conditions. The fiber optic temperature measurement system is calibration free and maintenance free, with low operating costs and high return on investment.

Kwa muhtasari, fiber optic temperature measurement technology has many advantages such as good stability, usahihi wa juu, usalama wa ndani, kupambana na kuingiliwa, kiasi kidogo, mbalimbali, na maisha marefu ya huduma, and has obvious technical advantages and application value in zero to low temperature environment monitoring. Katika siku zijazo, with the further development of fiber optic sensing technology, fiber optic temperature measurement will be more widely used in the field of low-temperature measurement.
