Fiber optic kutentha sensor, ntchito, makhalidwe

Ndi chitukuko chosalekeza chaukadaulo wozindikira, Kufuna kwa anthu kwaukadaulo wa sensa kumawonjezekanso tsiku ndi tsiku. Masensa a Fiber optic omwe amakumana ndi zovuta kwambiri, mtengo wotsika, njira yosavuta yokonzekera, ndipo kukhazikika kwabwino ndikosowa. M'kati mwa kuzindikira ndi kuzindikira, kukhudzika ndi kukhazikika ndizo zikuluzikulu zomwe zimalimbikitsa luso, pamene ndondomeko yokonzekera ndi mtengo ndizofunikira zomwe zimakhudza pakupanga mafakitale. Zomverera zomwe zimaphatikiza zabwinozi zikulandila chidwi komanso kuyanjidwa.

Fiber optic sensors ndi masensa omwe amasintha momwe chinthu chikupimidwa kukhala ma signature opimikika.. Mitundu yogwiritsira ntchito ya fiber optic sensors ndi yotakata kwambiri, kukhudza pafupifupi mbali zonse zofunika za chuma cha dziko ndi chitetezo, komanso moyo watsiku ndi tsiku wa anthu, makamaka kuti agwiritsidwe ntchito motetezeka komanso mogwira mtima m'malo ovuta. Mfundo yogwirira ntchito ya ma sensa a fiber optic ndikutumiza kuwala kochokera ku gwero la kuwala kupita ku modulator kudzera mu fiber optical.. Kuyanjana pakati pa modulator ndi magawo akunja omwe amayezedwa kumasintha mawonekedwe a kuwala kwa kuwala, monga mphamvu, kutalika kwa mafunde, pafupipafupi, gawo, polarization state, ndi zina., kukhala chizindikiro cha kuwala kosinthidwa. Kenako imatumizidwa kudzera mu fiber optical kupita ku chipangizo cha optoelectronic ndikusinthidwa kuti ipeze magawo omwe amayezedwa..

Muukadaulo womwe ulipo, pali njira zambiri zodziwira kutentha, ndipo masensa omwe amagwiritsidwa ntchito makamaka amaphatikizapo ma sensor a bimetallic kutentha, masensa kutentha kwa thermistor, ndi zida zowunikira kutentha kwa infrared. Masensa a kutentha awa ali ndi zovuta zosiyanasiyana, monga zoyezera kutentha kwa bimetallic kukhala tcheru ndi ma radiation a electromagnetic komanso osayenerera mawonekedwe a electromagnetic; Masensa a kutentha kwa thermistor amafunikira gwero lapano kuti likwezedwe pakagwiritsidwe ntchito, zomwe zimatha kudzitenthetsera pakapita nthawi. Masensa a kutentha kwa thermistor amakhudzidwa kwambiri ndi kudziwotcha, kuchititsa zolakwika zodziwotcha; Zipangizo zodziwira kutentha kwa infrared ziyenera kuchitika molunjika pamwamba pa chinthu chomwe chimadziwika poyezera kutentha, zomwe zimakhala zovuta kugwiritsa ntchito m'malo opapatiza.

Fiber optic temperature sensors have a wider range of applications due to their advantages of anti electromagnetic radiation and passive detection. The existing fiber optic kutentha masensa can be pre embedded in narrow spaces to achieve temperature measurement. Kwa zinthu zopanda kutentha kuyeza ulusi wa kuwala, pamene kuyeza kwa kutentha kumafunika, optical fiber kutentha sensa imathanso kukankhidwira mu chinthucho kudzera mu chipangizo chokoka;

Kuyeza kolondola kwa kutentha ndikofunikira pamakina ogwiritsira ntchito uinjiniya monga zakuthambo, ma lasers olimba kwambiri, ndi zida zamakina apamwamba kwambiri a CNC. Fiber optic kutentha masensa makamaka ntchito kuona kusintha kwa kunja kutentha kwa chilengedwe. Poyerekeza ndi masensa wamba magetsi, ma sensa a fiber optic alibe chosokoneza chamagetsi, kukana dzimbiri mwamphamvu, kupanga kosavuta, mtengo wotsika, kuyankha mwachangu, ndi kuzindikira kwakukulu.

Ubwino wa fiber optic kutentha masensa

1. Zomverera zachikhalidwe za kutentha sizingagwire ntchito bwino m'malo amagetsi amagetsi / mawayilesi chifukwa chosokoneza kwambiri;

2. Pali zofunika kwambiri kuti zikhale zolondola, kumva, utali wamoyo, kukhazikika/kudalirika, ndi zina;

3. Malo oyikapo ndi opapatiza ndipo pali zofunikira zapadera za kukula kwa sensa;

4. Zoyaka, zophulika, ndi malo owononga amakhala ndi zofunikira zapadera pachitetezo / kukana dzimbiri.

5. M'malo ovuta kwambiri monga kugunda kwamphezi ndi chipululu.

6. Malo omwe mphamvu zamagetsi zimakhala zovuta panthawi yoyesera.

FJINNO imapereka masensa a fulorosenti fiber kutentha, kugawa makina oyezera kutentha kwa fiber, ndi fiber Bragg grating sensors ndi osiyanasiyana ntchito, kulondola koyezera kutentha, ndi mitengo yabwino. Takulandirani kuti mutithandize

Fiber optic kutentha sensor, Njira yowunikira mwanzeru, Kugawidwa kwa fiber optic wopanga ku China
