Reed Switch ndi Hall Effect Sensors
Masensa a maginito amagwiritsidwa ntchito m'chilichonse kuyambira magalimoto mpaka mafoni. Ndi maginito ati omwe ndiyenera kugwiritsa ntchito ndi sensor yanga ya maginito? Kodi ndigwiritse ntchito sensa ya Hall effect kapena chosinthira bango? Kodi maginito akuyenera kulunjika bwanji ku sensa? Ndilolera ziti zomwe ndiyenera kuda nkhawa nazo? Phunzirani zambiri ndi K&J kuyenda-kupyolera mu kutchula kuphatikiza maginito-sensor.

Kodi Reed Switch ndi chiyani?

Masensa awiri a Hall effect ndi bango losinthira. Chosinthira bango chili kumanja.
Chosinthira bango ndi chosinthira chamagetsi chogwiritsidwa ntchito ndi maginito ogwiritsidwa ntchito. Zimakhala ndi zolumikizirana pa mabango achitsulo achitsulo mu emvulopu yagalasi yopanda mpweya. Zolumikizira nthawi zambiri zimatseguka, osalumikizana ndi magetsi. Kusinthaku kumayendetsedwa (kutsekedwa) pobweretsa maginito pafupi ndi switch. Maginito ikakokedwa, chosinthira bango chimabwerera komwe chinali.

Kodi Hall Effect Sensor ndi chiyani?
A Hall effect sensor ndi transducer yomwe imasinthasintha mphamvu yake yotulutsa potengera kusintha kwa maginito. Mwanjira zina, masensa a Hall effect amatha kugwira ntchito yofananira ngati chosinthira bango, koma opanda magawo osuntha. Ganizirani ngati gawo lokhazikika, labwino pakugwiritsa ntchito digito.

Ndi iti mwa masensa awiriwa omwe ali oyenera kugwiritsa ntchito kwanu zimadalira zinthu zingapo. Zomwe zimaphatikizira mtengo, kuyang'ana kwa maginito, kuchuluka kwa ma frequency (ma switch a bango nthawi zambiri sagwiritsidwa ntchito kupitilira 10 kHz), kudumpha kwa siginecha ndi kapangidwe ka logic yozungulira.

Magnet - Sensor Orientation
Kusiyana kwakukulu pakati pa masiwichi a bango ndi masensa a Hall effect ndiko kulowera koyenera komwe kumafunikira kuti maginito ayambitse. Masensa a Hall effect amatsegula pamene mphamvu ya maginito yomwe imakhala yokhazikika ku sensa yolimba-state ikugwiritsidwa ntchito. Ambiri amayang'ana mbali yakumwera kwa maginito kuti iyang'anizane ndi malo omwe akuwonetsedwa pa sensa, koma yang'anani pepala la sensa yanu. Mukatembenuza maginito kumbuyo kapena cham'mbali, sensa sikugwira ntchito.

Kusintha kwa bango ndi chipangizo chomakina chokhala ndi magawo osuntha. Zili ndi mawaya awiri a ferromagnetic olekanitsidwa ndi kampata kakang'ono. Pamaso pa mphamvu ya maginito yomwe ili yofanana ndi mawayawo, amakhudzana wina ndi mzake, kukhudza magetsi. Mwa kuyankhula kwina, maginito axis a maginito ayenera kukhala ofanana ndi kutalika kwa bango losinthira. Hamlin, wopanga ma switch a bango, ali ndi cholembera chabwino kwambiri pankhaniyi. Zimaphatikizapo zithunzi zazikulu zosonyeza madera ndi machitidwe omwe sensa idzayambitsa.
Kuyang'ana Koyenera kwa Magnet: Sensa ya Hall effect (kumanzere) vs. bango losinthira (kumanja)
Tiyenera kuzindikira kuti masinthidwe ena ndi otheka ndipo amagwiritsidwa ntchito nthawi zambiri. Mwachitsanzo, masensa a Hall effect amatha kuzindikira masamba achitsulo a "fan" yozungulira. Zitsulo za fanizi zimadutsa pakati pa maginito osasunthika ndi sensa yokhazikika. Chitsulo chikakhala pakati pa ziwirizi, mphamvu ya maginito imasunthidwa kutali ndi sensa (yotsekedwa) ndipo kusintha kumatsegula. Chitsulo chikachoka, maginito amatseka chosinthira
