Reed Switches da Hall Effect Sensors
Ana amfani da firikwensin maganadisu a cikin komai daga motoci zuwa wayoyin hannu. Wane irin maganadisu zan yi amfani da shi tare da firikwensin maganadisu? Shin zan yi amfani da firikwensin tasirin Hall ko maɓalli? Ta yaya magnet ya kamata a daidaita zuwa firikwensin? Wane haƙuri ya kamata in damu da su? Ƙara koyo tare da K&J tafiya-ta hanyar ƙayyadaddun haɗin magnet-sensor.

Menene Reed Switch?

Na'urori masu auna tasirin Hall guda biyu da maɓalli na reed. Canjin radiyo yana hannun dama.
Maɓallin Reed shine na'urar lantarki da ke aiki da filin maganadisu. Ya ƙunshi nau'i-nau'i na lambobin sadarwa a kan raƙuman ƙarfe na ƙarfe a cikin ambulan gilashin iska. Lambobin suna buɗewa kullum, ba sa tuntuɓar lantarki. Ana kunna maɓalli (rufe) ta hanyar kawo magnet kusa da mai kunnawa. Da zarar an cire magnet ɗin, maɓalli na reed zai koma matsayinsa na asali.

Menene Sensor Effect Hall?
Babban firikwensin tasirin Hall shine transducer wanda ke bambanta ƙarfin fitarwa don amsa canje-canje a filin maganadisu. A wasu hanyoyi, na'urori masu auna firikwensin Hall na iya yin irin wannan aiki a matsayin maɓalli na reed, amma ba tare da sassa masu motsi ba. Yi la'akari da shi a matsayin wani yanki mai ƙarfi, mai kyau ga aikace-aikacen dijital.

Wanne daga cikin waɗannan firikwensin guda biyu ya dace don aikace-aikacen ku ya dogara da abubuwa da yawa. Abubuwa sun haɗa da farashi, daidaitawar maganadisu, kewayon mitar (masu sauya radiyo yawanci ba a iya amfani da su fiye da 10 kHz), billa sigina da ƙirar ƙirar dabaru masu alaƙa.

Magnet – Sensor Orientation
Bambanci mai mahimmanci tsakanin maɓalli na reed da na'urori masu auna tasirin Hall shine daidaitaccen daidaitawa da ake buƙata don maganadisu mai kunnawa. Na'urori masu auna firikwensin zauren suna kunna lokacin da aka yi amfani da filin maganadisu wanda yake daidai da na'urar firikwensin jihar. Yawancin suna neman sandar kudanci ta magnet don fuskantar wurin da aka nuna akan firikwensin, amma duba takamaiman takaddar firikwensin ku. Idan ka juya maganadisu baya ko gefe, firikwensin ba zai kunna ba.

Reed switches ne na'urar inji mai motsi sassa. Ya ƙunshi wayoyi na ferromagnetic guda biyu waɗanda ke raba su da ƙaramin tazara. A gaban filin maganadisu wanda yake daidai da waɗancan wayoyi, za su taɓa juna, suna yin hulɗar lantarki. A wasu kalmomi, ma'aunin maganadisu na maganadisu ya kamata ya kasance daidai da doguwar axis na maɓalli na reed. Hamlin, mai ƙera reed switches, yana da kyakkyawan bayanin kula akan batun. Ya haɗa da manyan zane-zane masu nuna wurare da daidaitawar da firikwensin zai kunna.
Daidaitawar Magnet Mai Kyau: Na'urar firikwensin tasirin Hall (hagu) vs. mai sauya radiyo (dama)
Ya kamata a lura cewa wasu ƙa'idodi suna yiwuwa kuma sau da yawa ana amfani da su. Misali, na'urori masu auna firikwensin Hall na iya gano bakin karfe na “fan” mai juyawa. Gilashin ƙarfe na fan yana wucewa tsakanin magnet mai tsaye da firikwensin tsaye. Lokacin da karfe ke tsakanin su biyun, ana juyar da filin maganadisu daga firikwensin (an katange) kuma mai kunnawa yana buɗewa. Lokacin da karfe ya motsa, magnet yana rufe maɓallin
