ʻO nā pono a me nā hemahema o ka mika pae radar i hoʻohālikelike ʻia me ka mika pae ultrasonic

Radarmika paea me ka mika pae ultrasonic he mau mea ana pae i hoʻohana pinepine ʻia, eia nā pono a me nā hemahema o ka mika pae radar i hoʻohālikelike ʻia me ka mika pae ultrasonic:
pono
ʻO ke ana pololei kiʻekiʻe: hoʻohana ka mika pae radar i ke kumumanaʻo o ka microwave reflection e ana, ʻaʻole i hoʻopilikia ʻia e nā loli o ka mahana, ke kaomi, ka nui, ka haʻahaʻa a me nā mea ʻē aʻe, a kiʻekiʻe ke ana pololei, maʻamau a hiki i ka ± 1mm ​​a ʻoi aku paha. Hoʻopilikia nui ʻia ke ana pololei o ka mika pae ultrasonic e nā mea e like me nā ʻano waena a me ka mahana ambient, a ʻo ka pololei maʻamau ma kahi o ± 3mm-± 5mm.
Ka laulā o ka noi
Hoʻololi waena: Hiki i ka mika pae radar ke ana i ka pae wai o nā mea wai a me nā mea paʻa like ʻole, me ka corrosive, viscous, maʻalahi crystallization a me nā media kūikawā ʻē aʻe. Ke ana ʻana i ka medium me ka viscosity kiʻekiʻe, maʻalahi crystallization a i ʻole foam, hiki i ka mika pae ultrasonic ke loaʻa ka hōʻailona attenuation a i ʻole ka hoʻomālamalama paʻa ʻole.
Ka mahana kiʻekiʻe a me ke kaiapuni kaomi kiʻekiʻe: hiki i ka mika pae radar ke hana paʻa i ke kaiapuni ʻino o ka mahana kiʻekiʻe (a hiki i ka 400 ℃ a ʻoi aku paha) a me ke kaomi kiʻekiʻe (a hiki i ka 40MPa a ʻoi aku paha). Ma muli o ka palena o ka mea transducer a me ke kumumanaʻo, ʻo ka laulā o ka hoʻohana ʻana o ka mika pae wai ultrasonic i ke kaiapuni mahana kiʻekiʻe a me ke kaomi kiʻekiʻe he haiki iki.
Nui ka laulā: He nui ka laulā ana o ka mika pae radar, hiki ke hiki i nā ʻumi mika a i ʻole nā ​​​​haneli mika, a kūpono no ke ana ʻana i ka pae wai o nā pahu mālama nui a me nā hale kiaʻi kiʻekiʻe. ʻO ka laulā ana kūpono o ka mika pae ultrasonic maʻamau i loko o nā ʻumi mika.
Ka hiki ke kū'ē i ke komo ʻana: ʻaʻole i komo ke komo ʻana o ka hōʻailona microwave i hoʻopuka ʻia e ka mika pae radar e nā nalu electromagnetic o waho, nā nalu kani a me nā hōʻailona ʻē aʻe, a paʻa a hilinaʻi hoʻi ka hōʻailona. I ke kaiapuni me ka walaʻau ikaika, ka haʻalulu a i ʻole ka mahu, ua maʻalahi ka mika pae ultrasonic i ke komo ʻana, e hopena ana i ka hoʻonui ʻia o ka hewa ana.
He haʻahaʻa loa nā koi hoʻonohonoho: ʻaʻole ʻike ka mika pae radar i nā mea keakea a me nā mea hoʻonāukiuki i loko o ka pahu i ka wā e hoʻokomo ʻia ai, inā ʻaʻole i ālai ʻia ka antenna. ʻAʻole koi ka mika pae ultrasonic i nā mea keakea ma luna o ka pae wai, inā ʻaʻole e hoʻopilikia ia i ka hoʻolaha ʻana a me ka hoʻohuli ʻana o nā nalu kani, e hopena ana i ke ana pololei ʻole.
Kūlana haʻahaʻa
Kumukūʻai kiʻekiʻe: Kiʻekiʻe ke ʻano loea o ka mika pae radar, a paʻakikī ke kaʻina hana, no laila ʻoi aku ke kumukūʻai ma mua o ka mika pae ultrasonic, ka mea e kaupalena ana i kona laulā noi i kahi ʻano, ʻoiai i kekahi mau manawa koʻikoʻi ke kumukūʻai.
He paʻakikī ke ana ʻana i ka medium me ka dielectric constant liʻiliʻi: no ka medium me ka dielectric constant liʻiliʻi, nāwaliwali ka hōʻailona i hōʻike ʻia o ka nalu radar, kahi e hoʻopilikia ai i ka pololei o ke ana ʻana. ʻAʻole ʻike ka mika pae wai ultrasonic i ka dielectric constant o ka medium, a ʻoi aku ka kūpono no ke ana ʻana i ka medium me nā loli nui a liʻiliʻi paha i ka dielectric constant.
Aia kahi wahi makapō: aia kahi wahi makapō o ka mika pae radar ma kahi kokoke i ke kiko hoʻomaka o ke ana ʻana, ma ke ʻano he ʻumi kenimika a hiki i hoʻokahi mika, a ʻaʻole hiki ke ana i ka pae wai kokoke loa i ka lalo. He liʻiliʻi ka wahi makapō o ka mika pae ultrasonic, maʻamau ma waena o kekahi mau kenimika a me nā ʻumi kenimika.
ʻO ke komo ʻana o ka hōʻailona maikaʻi ʻole: ʻaʻole hiki i nā nalu radar ke komo i loko o nā mea hoʻomālamalama ikaika e like me ka metala, inā he metala ka ipu a me ka uhi kūloko a i ʻole ka papa insulation, hiki ke hoʻopilikia i ka hoʻolaha ʻana a me ka hoʻomālamalama ʻana o nā nalu radar, pono e hoʻohana i kahi ʻano hoʻonohonoho kūikawā a koho paha i ke kumu hoʻohālike ana pae radar kūpono. Hiki i ka nalu kani o ka mika pae ultrasonic ke komo i loko o kahi mānoanoa o nā mea ʻaʻole metala, a maikaʻi ka hoʻololi ʻana o ka mea a me ke ʻano o ka ipu.
