Kev xaiv cov khoom siv hlau nplaum tas mus li thiab siv cov khoom siv hlau nplaum

Kev xaiv ntawmCov khoom siv hlau nplaum ruaj khovrau Magnetic Reed Sensor

Feem ntau hais lus, xaiv cov hlau nplaum rau cov hlau nplaum sib nqus hloov sensor yuav tsum xav txog ntau yam kev thov, xws li kev ua haujlwm kub, demagnetization effect, sib nqus teb zog, ib puag ncig tus yam ntxwv, txav thiab daim ntawv thov. Cov yam ntxwv tseem ceeb rau hom nrov tshaj plaws ntawm cov khoom siv hlau nplaum nyuaj raws li hauv qab no:

Rare Earth Neodymium-Iron-Boron Magnet

1. Cov khoom siv hluav taws xob siab tshaj plaws

2. Siab heev remanance thiab coercivity

3. Tus nqi qis

4. Lub zog siv tshuab zoo dua li cov hlau nplaum Samarium Cobalt

Rare Earth Samarium Cobalt Magnet

1. High sib nqus zog khoom

2. Haum rau kev ua haujlwm siab

3. Siab demagnetization kuj

4. Zoo heev thermal stability

5. High corrosion kuj

6. Cov hlau nplaum kim tshaj plaws

7. Siv nyob rau hauv qhov kub txog li 350 ° C

Alnico Magnet

1. pheej yig dua cov hlau nplaum hauv ntiaj teb tsawg

2. Kev ua haujlwm siab tshaj plaws rau 550 ℃

3. Yam tsawg kawg nkaus kub coefficient

4. Tsawg coercivity

5. High residual induction

Ferrite los yog Ceramic Magnet

1. Khov

2. pheej yig tshaj ntawm cov khoom siv hlau nplaum plaub

3. Ua haujlwm tsis pub dhau 300 ° C

4. Kev sib tsoo yuav tsum ua kom tau raws li kev ua siab ntev

5. High corrosion kuj

Daim ntawv thov tseem ceeb ntawm Magnetic Switch Sensor

1. Lub sensor ceev ntawm lub tsheb kauj vab yog siv nrogcylindrical Neodymium hlau nplaum.

2. Sib nqus reed hloov yog tshwj xeeb hauv cov kua dej sib kis. Cov hlau nplaum hloov tau tuaj yeem ntsia ncaj qha rau ntawm lub tog raj kheej thaiv. Thaum lub piston nrog lubSmCo hlau nplaum nplhaibtxav mus rau txoj hauj lwm ntawm lub magnetic hloov, ob lub hlau reeds nyob rau hauv lub magnetic hloov yog rub nyob rau hauv nyob rau hauv qhov kev txiav txim ntawm lub magnetic teb ntawm lub nplhaib sib nqus xa cov teeb liab. Thaum lub piston txav mus deb, tus nplaig caij nplooj ntoos hlav hloov tawm ntawm qhov chaw sib nqus, qhov kev sib cuag tau qhib thiab lub teeb liab raug txiav tawm. Ua li no, txoj hauj lwm ntawm lub tog raj kheej piston tuaj yeem pom tau yooj yim.

3. Lwm hom kev sib nqus reed hloov yog qhov hloov tshiab sib nqus sib nqus, sib nqus hloov sensor, tseem hu ua magnetic induction hloov. Nws muaj lub plhaub yas, uas encapsulates lub reed hloov nyob rau hauv lub plhaub dub thiab coj tawm cov hlau. Lwm ib nrab ntawm lub plhaub yas nrog cov hlau nplaum nyuaj yog tsau rau ntawm qhov kawg. Thaum lubhlau nplaum nyuajyog nyob ze rau qhov hloov nrog hlau, nws xa tawm lub teeb liab hloov. Lub teeb liab dav dav yog 10mm. Cov khoom no yog siv dav hauv qhov rooj tiv thaiv tub sab, lub qhov rooj hauv tsev, tshuab luam ntawv, fax tshuab, xov tooj, thiab lwm yam khoom siv hluav taws xob thiab khoom siv.

4. Lub qhov rooj tub yees siv lub reed hloov rau lub qhov rooj kaw. Cov hlau nplaum ruaj khov yog mounted rau ntawm lub qhov rooj thiab cov hlau nplaum reed sensor yog txuas nrog ib lub thav duab ruaj khov rau hauv qab ntawm phab ntsa sab nrauv ntawm lub tub yees. Thaum lub qhov rooj qhib, lub reed sensor tsis tuaj yeem ntes cov magnetic teb, ua rau lub teeb LED teeb. Thaum lub qhov rooj kaw, lub ntsuas hluav taws xob sib nqus pom qhov tsim nyog sib nqus thiab LED tawm mus. Hauv daim ntawv thov no, lub microcontroller hauv lub cuab yeej tau txais lub teeb liab los ntawm lub reed sensor, thiab tom qab ntawd lub chaw tswj tau qhib lossis kaw lub LED.
