Classification of Fiber Optic Sensors and Application of Fiber Optic Temperature Sensors-INNO

Brand of sensor ya joto ya fiber optic

A true brand ranking may not necessarily fully introduce so many domestic enterprises. Some well-known domestic brands of fiber optic temperature sensors include FJINNO, while other companies in the top 10 are not introduced.

Fiber optic sensors are sensors developed based on optical signals. The traditional temperature measurement method is based on signals such as thermocouples, vifaa vya joto, and pyroelectric detectors. The development of temperature sensors has been many years, and fiber optic sensors can be widely used in situations with strong electromagnetic interference or flammable and explosive materials. Traditional temperature sensors based on other temperature measurement methods will be greatly limited.

Sensor ya joto ya fiber optics and measurement technology are important development directions in the power electrical industry. Due to its small size, uzito mwepesi, kubadilika, insulation nzuri ya umeme, flexible bending, upinzani wa kutu, large measurement range, na unyeti wa juu, optical fibers can serve as a reminder and expand the range of use in other temperature sensors, achieving products and methods that traditional temperature sensors cannot measure temperature.

In addition to its unique applications in temperature measurement, fiber optic sensing technology also has the characteristics of fast response, bendi ya masafa pana, isiyoweza kulipuka, flameproof, and electromagnetic interference resistance compared to traditional temperature measurement instruments.

Kanuni ya msingi ya kufanya kazi ya vitambuzi vya fiber optic ni kutuma mawimbi ya mwanga kutoka chanzo cha mwanga kupitia optic ya nyuzi hadi kwenye moduli., kusababisha vigezo vilivyopimwa kuingiliana na mwanga unaoingia katika eneo la moduli, kusababisha mabadiliko katika mali ya macho ya mwanga (kama vile ukali, urefu wa mawimbi, masafa, awamu, hali ya ubaguzi, nk.), kuwa chanzo cha ishara kilichobadilishwa. Baada ya kutumwa kwa njia ya fiber optic kwa photodetector na demodulated, vigezo vilivyopimwa vinapatikana.

The application scope of fiber optic sensors

The characteristics of fiber optic sensors are sensitivity, usahihi, strong adaptability, compactness, na akili. Fiber optic has many unique characteristics compared to other sensors, such as resistance to electromagnetic and atomic radiation interference, fine diameter, soft texture, and light weight; Uhamishaji joto, upinzani wa maji, upinzani wa joto la juu, upinzani wa kutu, nk. It can be used in areas that are inaccessible to humans (such as high temperature areas) or areas that are harmful to humans (such as nuclear radiation areas), and can also transcend human physiological boundaries to receive external information that human senses cannot perceive.

Characteristics of fiber optic sensors

1、 Unyeti wa juu;

2、 Fast reaction speed;

3、 We can develop various types of sensors, such as acoustic sensors, sensorer joto, sensorer shinikizo, nk;

4、 Upeo mpana wa maombi, voltage ya juu, kelele ya umeme, joto la juu, kutu, or other harsh environments;

5、 And it has inherent compatibility with fiber optic telemetry technology.

The advantage of fiber optic sensors is that compared with traditional sensors, fiber optic sensors use light as the carrier of sensitive information and fiber optic as the medium for transmitting sensitive information. They have the characteristics of fiber optic and optical measurement, and have a series of unique advantages. Good electrical insulation performance, upinzani mkubwa kwa kuingiliwa kwa sumakuumeme, non invasiveness, unyeti mkubwa, easy to achieve remote monitoring of the measured signal, upinzani wa kutu, isiyoweza kulipuka, flexible optical path, and easy to connect with computers.

Sensor ya macho ya nyuzi maombi

Fiber optic sensors can be used for measuring physical quantities such as displacement, mtetemo, mzunguko, shinikizo, kupinda, mkazo, kasi, kuongeza kasi, ya sasa, magnetic field, voltage, unyevunyevu, joto, sound field, kiwango cha mtiririko, concentration, pH value, na matatizo. The application range of fiber optic sensors is very wide, involving almost all important fields in the national economy and defense, as well as people’s daily lives. Especially, they can be used safely and effectively in harsh environments, solving many technical problems that have existed in industries for many years, and have great market demand. Mainly manifested in the following applications:

The application of interferometric gyroscopes and grating pressure sensors in urban construction, kama vile madaraja, mabwawa, and oil fields. Fiber optic sensors can be embedded in concrete, carbon fiber reinforced plastics, and various composite materials to test stress relaxation, construction stress, and dynamic load stress, in order to evaluate the structural performance of bridges during short-term construction and long-term operation.

Katika mfumo wa nguvu, ni muhimu kupima vigezo kama vile joto na sasa, kama vile ugunduzi wa hali ya joto kwenye stator na rota ya transfoma yenye voltage ya juu na motors kubwa. Kwa sababu ya unyeti wa sensorer za umeme kwa kuingiliwa kwa sumakuumeme, haziwezi kutumika katika hali kama hizi na zinaweza kutumika tu na sensorer za fiber optic. Fiber optic iliyosambazwa vihisi joto ni teknolojia ya hali ya juu iliyotengenezwa katika miaka ya hivi karibuni kwa kipimo cha wakati halisi cha usambazaji wa eneo la joto la anga. Distributed fiber optic temperature sensing systems sio tu kuwa na faida za sensorer za fiber optic zima, lakini pia kuwa na uwezo wa kuhisi wa kusambaza halijoto katika sehemu mbalimbali kando ya mstari wa nyuzi macho. Pamoja na kipengele hiki, tunaweza kuendelea kupima halijoto katika sehemu mbalimbali ndani ya kilomita chache kando ya mstari wa nyuzi macho kwa wakati halisi, kwa usahihi wa nafasi ya hadi mita na usahihi wa kipimo cha hadi 1 shahada, kuzifanya zifae sana kwa matumizi makubwa ya kipimo cha joto cha makutano.

Aidha, vitambuzi vya nyuzi macho vinaweza pia kutumika katika ufuatiliaji wa reli, mifumo ya kusukuma roketi, na kugundua kisima cha mafuta.

Fiber optic ina faida kubwa katika broadband, large capacity, maambukizi ya umbali mrefu, na uwezo wa kufikia parameter nyingi, kusambazwa, and low-energy sensing. Fiber optic sensing can continuously absorb new technologies and devices from fiber optic communication, and various fiber optic sensors are expected to be widely applied in the Internet of Things.
