Kusankhidwa kwa Zida Zosatha za Magnet ndi Kugwiritsa Ntchito Magnetic Reed Sensors

Kusankhidwa kwaZinthu Zosatha za Magnetkwa Magnetic Reed Sensor

Nthawi zambiri, kusankha maginito kwa maginito a reed switch sensor kumafunika kuganizira zinthu zosiyanasiyana zogwiritsira ntchito, monga kutentha kwa ntchito, demagnetization effect, mphamvu ya maginito, mawonekedwe a chilengedwe, kuyenda ndi kugwiritsa ntchito. Zinthu zazikuluzikulu zamitundu yotchuka kwambiri yamagetsi olimba motere:

Maginito Osowa Padziko Lapansi Neodymium-Iron-Boron

1. Zopangira mphamvu zapamwamba kwambiri

2. Kukhazikika kwakukulu komanso kukakamiza

3. Mtengo wotsika

4. Mphamvu zamakina bwino kuposa maginito Samarium Cobalt

Rare Earth Samarium Cobalt Magnet

1. High maginito mphamvu mankhwala

2. Oyenera ntchito mkulu ntchito

3. High demagnetization kukana

4. Kukhazikika kwabwino kwamafuta

5. High dzimbiri kukana

6. Maginito okwera mtengo kwambiri

7. Amagwiritsidwa ntchito kutentha mpaka 350 ° C

Alnico Magnet

1. Zotsika mtengo kuposa maginito osowa padziko lapansi

2. Kutentha kwakukulu kwa ntchito kufika pa 550 ℃

3. Kuchepetsa kutentha kwapakati

4. Kukakamiza kochepa

5. High yotsalira kulowetsedwa

Ferrite kapena Ceramic Magnet

1. Wopepuka

2. Zotsika mtengo kwambiri pakati pa zida zinayi za maginito

3. Kugwira ntchito mkati mwa 300 ° C

4. Kupera kumafunika kukwaniritsa zololera

5. High dzimbiri kukana

Ntchito Zazikulu za Magnetic Switch Sensor

1. Sensa yothamanga panjinga imagwiritsidwa ntchito ndicylindrical Neodymium maginito.

2. Maginito bango lophimba ndi wapadera dongosolo madzimadzi kufala. Kusintha kwa maginito kumatha kukhazikitsidwa mwachindunji pa cylinder block. Pamene pisitoni ndiSmCo maginito mpheteimasunthira pamalo a switch ya maginito, mabango awiri achitsulo mu switch ya maginito amakokedwa pansi pakuchita kwa maginito a mphete ya maginito kutumiza chizindikiro. Pistoni ikachoka, kusintha kwa lilime kumasiya mphamvu ya maginito, kulumikizana kumatseguka ndipo chizindikirocho chimadulidwa. Mwanjira imeneyi, malo a pistoni ya silinda amatha kudziwika mosavuta.

3. Mtundu wina wa maginito bango lophimba ndi latsopano maginito moyandikana lophimba, maginito lophimba sensa, wotchedwanso maginito kupatsidwa ulemu lophimba. Ili ndi chipolopolo cha pulasitiki, chomwe chimatsekereza bango mu chipolopolo chakuda ndikutulutsa waya. Theka lina la chipolopolo cha pulasitiki chokhala ndi maginito olimba chimakhazikika kumapeto kwina. Pamene amaginito olimbaili pafupi ndi chosinthira ndi waya, imatumiza chizindikiro chosinthira. Kutalika kwa chizindikiro ndi 10mm. Izi zimagwiritsidwa ntchito kwambiri pazitseko zotsutsana ndi kuba, zitseko zapakhomo, osindikiza, makina a fax, matelefoni, ndi zida zina zamagetsi ndi zida.

4. Khomo la firiji limagwiritsa ntchito chosinthira bango pozindikira kutseka kwa chitseko. Maginito okhazikika amayikidwa pakhomo ndipo sensor ya magnetic reed imagwirizanitsidwa ndi chimango chokhazikika chobisika kuseri kwa khoma lakunja la firiji. Chitseko chikatsegulidwa, sensor ya bango silingazindikire mphamvu ya maginito, zomwe zimapangitsa kuti babu ya LED iwunikire. Chitseko chikatsekedwa, sensa ya maginito imazindikira mphamvu ya maginito yoyenera ndipo LED imatuluka. Pogwiritsa ntchito izi, microcontroller mu chipangizocho amapeza chizindikiro kuchokera ku sensa ya bango, ndiyeno gawo lowongolera limatsegula kapena kuletsa LED.
