Reed Sensors vs. Hall Effect Sensors

Hall Effect na'urori masu auna firikwensin kuma suna amfani da kasancewar ƙarfin maganadisu don kunna buɗewa da rufewar na'urar, amma a nan ne kamanninsu ke ƙare. Waɗannan na'urori masu auna firikwensin su ne na'urori masu motsi na semiconductor waɗanda ke samar da wutar lantarki don kunna ƙwanƙwaran juzu'i maimakon masu juyawa tare da sassa masu motsi. Wasu bambance-bambance masu mahimmanci tsakanin nau'ikan sauyawa biyu sun haɗa da:

Dorewa. Hall Effect na'urori masu auna firikwensin na iya buƙatar ƙarin marufi don kare su daga mahalli, yayin da na'urori masu auna firikwensin suna da kariya a cikin kwantena da aka rufe. Koyaya, tunda na'urori masu auna firikwensin reed suna amfani da motsi na inji, sun fi saurin lalacewa da tsagewa.
Bukatar wutar lantarki. Maɓallin Tasirin Hall yana buƙatar ci gaba da gudana na halin yanzu. Na'urori masu auna firikwensin Reed, a gefe guda, suna buƙatar ƙarfi kawai don samar da filin maganadisu na ɗan lokaci.
Rashin lahani ga tsangwama. Maɓallan Reed na iya zama mai saurin girgiza injina a wasu mahalli, yayin da Maɓallin Tasirin Hall ba. Maɓallin Tasirin Hall, a gefe guda, sun fi kamuwa da shisshigi na lantarki (EMI).
Kewayon mita. Ana iya amfani da na'urori masu auna firikwensin zaure a kan kewayon mitar mai faɗi, yayin da na'urori masu auna firikwensin yawanci suna iyakance ga aikace-aikace masu mitoci ƙasa da 10 kHz.
Farashin Duk nau'ikan firikwensin suna da tsada-tsari, amma gabaɗaya na'urori masu auna firikwensin rahusa suna da arha don samarwa, wanda ke sa na'urori masu auna firikwensin Hall Effect ɗan tsada.
Yanayin zafi. Na'urori masu auna firikwensin Reed suna yin aiki mafi kyau a cikin matsanancin zafi ko sanyi, yayin da na'urori masu auna firikwensin Hall Effect sukan fuskanci matsalolin aiki a matsanancin zafin jiki.
