Inde, ma transmitter a radar level amagwiritsidwa ntchito kwambiri poyesa zinthu zolimba monga ufa, tirigu, simenti, malasha, ndi ma pellets. Komabe, magwiridwe antchito awo amadalira zinthu zingapo komanso zinthu zomwe zimayikidwa.
1. Momwe Radar Imayezera Zinthu Zolimba
Ma transmitter a radar level amatulutsa zizindikiro za microwave kupita pamwamba pa chinthucho. Zizindikirozi zimabwereranso ku antenna, ndipo chipangizocho chimawerengera mlingo kutengera nthawi yomwe chizindikirocho chikuuluka.
Pa zinthu zolimba, pamwamba nthawi zambiri pamakhala posagwirizana komanso pamakhala mphamvu, kotero chizindikiro chowonetsedwa chimatha kusiyana poyerekeza ndi chamadzimadzi. Zipangizo zamakono za radar zimagwiritsa ntchito njira zoyendetsera zizindikiro kuti zitsimikizire kuti kuwerenga kwake kuli kokhazikika.
2. Zipangizo Zolimba Zoyenera
Ma transmitter a radar level amagwira ntchito bwino ndi:
Tirigu (tirigu, chimanga, mpunga)
Ufa (simenti, ufa, laimu)
Ma granules ndi ma pellets
Mchenga, miyala, ndi mchere
3. Mavuto Ofunika Poyesa Zinthu Zolimba
a. Malo Ozungulira Fumbi
Fumbi lochuluka likadzaza kapena kutulutsa zinthu lingathe kuchepetsa chizindikiro cha radar, makamaka pazida zomwe sizimalandira ma frequency ambiri.
b. Malo Osafanana (Ngodya ya Mpumulo)
Zinthu zolimba kwambiri zimapanga mawonekedwe ofanana ndi a koni, zomwe zimapangitsa kuti chizindikiro chizibalalika komanso kuti muyeso wake ukhale wosiyana.
c. Dielectric Constant Yotsika
Ufa wina (monga ma pellets apulasitiki) umakhala ndi mphamvu yochepa yowunikira, zomwe zimapangitsa kuti kuzindikira zizindikiro kukhale kovuta.
d. Kumanga kwa Antena
Zipangizo zomata zimatha kuwunjikana pa antenna, zomwe zimakhudza kutumiza kwa chizindikiro.
4. Mtundu Wabwino Kwambiri wa Radar wa Zolimba
Radar yosakhudzana (makamaka 80GHz) nthawi zambiri imakondedwa pazinthu zolimba chifukwa:
Ngodya yopapatiza ya denga → kuyang'ana bwino, kumapewa kusokonezedwa ndi makoma a silo
Ma frequency apamwamba → kuwunikira kwamphamvu kwa chizindikiro kuchokera ku zinthu zolimba
Kuchita bwino m'malo opanda fumbi
Ma radar ocheperako (monga 6GHz) angagwiritsidwe ntchito pa malo akuluakulu okhala ndi fumbi kwambiri, koma osalondola kwenikweni.
5. Njira Zabwino Zokhazikitsira
Kuti muwonetsetse kuti muyeso ndi wolondola:
Ikani kutali ndi malo olowera zinthu kuti mupewe fumbi lochuluka ndi kugwa kwa zinthuzo
Pewani nyumba zamkati (makwerero, matabwa) zomwe zingayambitse mawu abodza
Gwiritsani ntchito ngodya yoyenera yoyikira kapena zipangizo zowunikira ngati pakufunika
Onetsetsani kuti pali malo okwanira oti mutuluke kuchokera ku makoma a silo
Ma transmitter a radar level ndi njira yabwino kwambiri yoyezera zinthu zolimba monga ufa ndi tirigu, makamaka pogwiritsa ntchito radar yosagwirizana ndi ma frequency ambiri (80GHz). Ndi kusankha ndi kukhazikitsa koyenera, amapereka muyeso wodalirika, wosakhudzana ndi ma frequency, komanso wosakonzedwa bwino ngakhale m'malo ovuta okhala ndi silo.
