He aha ke kiʻikuhi inductive?

Hoʻohana nā ʻōnaehana automated modern i kahi nui o nā mea ʻike i ʻokoʻa i nā ʻano a me ke kumu hana. ʻO kekahi o nā mea i ʻike pinepine ʻia i hoʻohana ʻia i nā kula he nui (me ka ʻoihana ʻenehana) ʻo ia ka mea hoʻopihapiha hoʻokomo, a e nānā nui mākou iā ia i kēia manawa.

He aha ke kiʻikuhi inductive?

Ma o kāna ʻano, pili kēia mea ʻike i nā pono pili ʻole. I nā huaʻōlelo ʻē aʻe, ʻaʻole pono ke kokoke i ke kino i kahi mea i mea e hoʻoholo ai i kona wahi i ka lewa.

Hoʻohana pinepine ʻia nā mea hoʻoluhi inductive inā pono e hana me nā mea metala a me nā metala i kahi ʻano hana paʻakikī.

Pehea e hana ai i kahi mea hoʻowalewale inductive?

Ma muli o kona ʻano kūloko, loaʻa i ka mea hoʻopili inductive kekahi mau kumu hana. Hoʻohana ʻia kahi mīkini hana kūikawā ma aneʻi, kahi e hoʻopuka ai i kahi amplitude vibration. Ke komo kahi mea hao a ferromagnetic paha i ke kahua o ka sensor, hoʻomaka e heluhelu a hoʻololi ʻia nā haʻalulu.

E hoʻomaʻalahi mākou pehea e hana ai ...

E hoʻomaka i ka hana, hana ʻia ka mea ʻike, nāna e hāʻawi i ka hoʻokumu ʻia ʻana o ka pā magnet. ʻO kēia māla, e hana i nā kahawai eddy e hoʻololi i ka amplitude o oscillations i kahi mīkini hana holo.

ʻO ka hopena o kēia mau hoʻololi ʻana a pau kahi hōʻailona hōʻailona e hiki ke loli ma muli o ka mamao ma waena o ka mea hoʻopili inductive a me ka mea hoʻāʻo.

ʻO ka hōʻailona i hele mua ʻia mai ke kiʻiona he analog, a hoʻololi ʻia i ka loiloi e kahi mea kūikawā i kapa ʻia he trigger.

He aha nā mea o ka mīkini kokoke?

ʻOiaʻiʻo, aia nā ʻano like ʻole o nā sensor inductive, akā ua hui pū ʻia lākou e ka mea i loaʻa i nā mea nui:

Mīkini hana wāwahie

ʻO ka mea nui i kēia ʻano hāmeʻa ka mīkini hana, no ka mea, hana ia i kahua electromagnetic e kōkua ai e ʻike a kālailai i nā mea hao a hoʻoholo i ko lākou kūlana. Me ka ʻole o ka generator a me ka māla e hana ai, ʻaʻole hiki ke hana o kahi sensor inductive.

Hoʻololi hōʻailona

ʻO kēia mea e like me ke kumu, a ʻo kāna hana ʻo ia ke hoʻololi i ka hōʻailona i hiki i ka sensor ke launa pū me nā mea ʻē aʻe o ka ʻōnaehana e hoʻouna hou i ka ʻike.

Mea hoʻonui

Pono kahi mea hoʻonui i mea e hiki ai i ka hōʻailona i loaʻa i ka pae i makemake ʻia o ka lawe hou ʻana.

Nā hōʻailona LED

Mālama nā ʻōkuhi LED i ka hana o ke kiʻikuhi a hōʻike i ka mea aia a i ʻole ke holo nei nā ʻōnaehana like ʻole.

Ka hale noho

Loaʻa i ke kino nā mea āpau i luna

Nā ʻano o nā mea ʻike i nā ʻōnaehana kaʻa a ma kahi e hoʻohana ʻia ai kahi mea ʻike inductive

ʻAʻole hiki ke noʻonoʻo ʻia nā ʻōnaehana hoʻokele uila no nā kaʻa o kēia ao me ka ʻole o nā mea ʻike. Hoʻohana ʻia nā ʻano sensor like ʻole i nā ʻōnaehana kaʻa holo ʻokoʻa. Ana ke kaʻa i ka mahana a me ke kaomi o ka ea, wahie, aila, coolant.

Hoʻopili ʻia nā mea ʻike a me nā wikiwiki i nā ʻāpana e neʻe ana o ke kaʻa e like me ka crankshaft, mea hoʻokaʻawale, throttle, nā pū kī, EGR valve, a me nā mea hou aʻe. Hoʻohui ʻia, hoʻohana ʻia ka nui o nā mea ʻike i nā ʻōnaehana palekana kaʻa.

Ke kaukaʻi ʻia nei ke kumu, hoʻokaʻawale ʻia nā mea ʻike kaʻa i ke kūlana a me nā mea wikiwiki, nā mea e kahe ana ka lewa, ka hoʻokuʻu ʻana, ka mahana, kaomi a me nā mea ʻē aʻe

Hoʻohana ākea nā mea hoʻopili inductive e ana i ka wikiwiki a me ke kūlana o nā ʻāpana e hoʻohuli ana, akā me he mea lā ʻo ka hoʻohana nui loa o kēia ʻano sensor i ka ʻimi ʻana i ke kūlana a me ka wikiwiki o ka crankshaft engine.

Ma muli o ka hilinaʻi nui o nā sensor inductive, keu hoʻi ke hana nei i nā ʻano paʻakikī, hoʻohana nui ʻia lākou ʻaʻole wale nō i ka ʻoihana kaʻa, akā i ka pūʻali koa, ke kaʻaahi, kahi ākea a me nā ʻoihana kaumaha.

He aha hou aʻe e pono ai mākou e ʻike e pili ana i kahi sensor inductive?

ʻO kahi wahi inductive a me ka sensor wikiwiki kahi mea me kāna mau kikoʻī, no laila, i ka wehewehe ʻana o kāna hana, hoʻohana ʻia nā wehewehe kūikawā, e like me:

ʻĀpana hana

ʻO kēia ke ʻano o ka ʻāpana kahi e haʻi nui ai ke kekelē o ka mākia mākia. Aia ke kumu i mua o ka ʻāpana ʻāpiki o ka mea ʻike ma kahi o ke kiʻekiʻe o ka mānoanoa.

Ka mamao kuapo Nominal

Manaʻo ʻia kēia parameter i ka manaʻo no ka mea ʻaʻole ia e noʻonoʻo i nā ʻano hana, nā ʻano mahana, nā pae uila, a me nā kumu ʻē aʻe.

Laulā hana

Hōʻike ka pae hana i nā palena e hōʻoia i ka hana pono a me ka maʻamau o ka sensor inductive.

Kumumea hoʻoponopono

Pili ka mea hoʻoponopono i nā mea i hana ʻia ai ka mea metala, i nānā ʻia e ka mea ʻike.

Nā mea maikaʻi a me nā maikaʻi ʻole o nā sensor inductive
E like me nā hāmeʻa ʻē aʻe, loaʻa i nā mea hoʻopili inductive ko lākou ikaika a me nā nāwaliwali.

I waena o nā mea nui loa nā mea maikaʻi o kēia ʻano o nā mea ʻike:

• Kūkulu maʻalahi. He maʻalahi loa ka hoʻolālā ʻana o nā mea hoʻopili inductive a ʻaʻohe i loko o nā mea paʻakikī e koi ai i kahi hoʻonohonoho kūikawā. No laila, loaʻa i nā mea ʻike ke kūlana kiʻekiʻe o ka ikaika a me ka hilinaʻi, paʻakikī ʻole e haki, a ʻo ka ʻoiaʻiʻo hiki ke hoʻohana ʻia no kahi manawa lōʻihi loa.

• · Nā hiʻohiʻona kūikawā - nā hiʻohiʻona o nā mea ʻike inductive e ʻae iā ʻoe e hoʻokomo a hoʻohui iā lākou i nā ʻāpana o ka ʻōnaehana kaʻa.

• · Sensitivity - naʻaupō o kēia ʻano, hiki ke hoʻohana ʻia i ka wā e hana ai me nā ʻāpana metala a me nā mea like ʻole.

ʻO ka drawback wale nō ka mea hiki i nā sensors ke hoʻohuli ʻia e nā ʻano kūwaho like ʻole i ka wā o ka hana, a no laila he mea pono e hāʻawi i nā kūlana kūpono e hoʻopilikia ʻole i ka hana pololei o nā sensor inductive.

He aha ka mea e noʻonoʻo ai i ke koho ʻana i nā sensor inductive?

Puka

Loaʻa nā mea ʻike inductive i nā ʻano like ʻole, akā ʻo ka mea maʻamau he ʻano cylindrical me nā kaula e holo ana i ka lōʻihi o ka sensor. ʻO ke kaula hoʻohālikelike pae maʻamau ʻo M 5, M 8, M 12, M 18 a me M 30.

Ka mamao pane

Aia ia i nā ʻano kikoʻī o ka generator, i hoʻopili ʻia e nā au eddy o ke kūlana i ana ʻia. ʻOkoʻa ka laulā mai ka 1 mm. a hiki i 25 - 30 mm. ma muli o ka mea hana.

ʻAno mīkini paʻi

ʻO ka maʻamau nā mea ʻike he analog (1-10V, 4-20mA) a me nā kikohoʻe. Hoʻokaʻawale ʻia nā mea hope i ke ʻano PNP a me ke ʻano NPN. Eia hou, he mea nui e hoʻoholo inā loaʻa i ka mea ʻike he mea wehe maʻamau (NO) a pani ʻia paha (NC).

Ka uea

ʻO ka maʻamau he uwea ʻelua a ʻekolu paha uea ka hoʻohana ʻia, akā hiki ke hoʻopili ʻia ka mea ʻike i ka mea hoʻopili.

Nā nīnau a me nā pane:

He aha nā loina hana a me nā hoʻohana ʻana o nā sensor inductive? Ke hana nei kēlā mau mea ʻike ma muli o ka hoʻololi ʻana i ka māla magnetic i ka coil i ka wā e komo ai kahi mea metala i kahi o ka magnet. Aia kekahi laʻana ma nā oscilloscopes, ammeters, a me nā holoi kaʻa.

Pehea e hana ai nā mea ʻike induction? Ana lākou i ka nui o ka ikaika electromotive o ka induction. Ke kahe ka au i ka wili o ka mea ike, a maalo kekahi mea metala, e hoololi ia i ka ikaika o ke kahua magnetic, a ike ka mea ike i ke alo o keia mea.

He aha nā mea ʻike inductive? Paʻa paʻa kiʻekiʻe, uea pālua, metala a pau, pale wela, pale i ke kahua magnetic, pahū, annular, tubular a me ka maʻamau.
