Izinzwa ze-Reed vs. Hall Effect Sensors

Izinzwa ze-Reed vs. Hall Effect Sensors

Izinzwa ze-Hall Effect zisebenzisa nokuba khona kwamandla kazibuthe ukunika amandla ukuvula nokuvalwa kweswishi, kodwa kulapho ukufana kwazo kuphelela khona. Lezi zinzwa zingama-semiconductor transducers akhiqiza i-voltage ukuze enze amaswishi e-solid-state asebenze kunokushintshwa okunezingxenye ezihambayo. Eminye umehluko oyinhloko phakathi kwezinhlobo ezimbili zokushintshwa zihlanganisa:

Ukuqina. Izinzwa ze-Hall Effect zingase zidinge ukupakishwa okwengeziwe ukuze zivikelwe endaweni ezungezile, kuyilapho izinzwa zomhlanga zivikelwe ngaphakathi kweziqukathi ezivalwe nge-hermetically. Kodwa-ke, njengoba izinzwa zomhlanga zisebenzisa ukunyakaza kwemishini, kulula kakhulu ukuguga.
Isidingo sikagesi. Ukushintsha kwe-Hall Effect kudinga ukugeleza okuqhubekayo kwamanje. Izinzwa zomhlanga, ngakolunye uhlangothi, zidinga kuphela amandla okukhiqiza inkambu kazibuthe ngezikhathi ezithile.
Ukuba sengozini kokuphazamiseka. Ukushintsha komhlanga kungase kuthambekele ekushaqekeni komshini ezindaweni ezithile, kuyilapho amaswishi e-Hall Effect engekho. Ngakolunye uhlangothi, amaswishi e-Hall Effect, asengozini enkulu yokuphazanyiswa yi-electromagnetic (EMI).
Ibanga lemvamisa. Izinzwa zomphumela wehholo ziyasebenza ebangeni elibanzi lefrikhwensi, kuyilapho izinzwa zomhlanga zivame ukukhawulelwa ezinhlelweni zokusebenza ezinamaza angaphansi kuka-10 kHz.
Izindleko. Zombili izinhlobo zezinzwa zibiza kancane, kodwa izinzwa zomhlanga ziphelele zishibhile ukukhiqiza, okwenza izinzwa ze-Hall Effect zibize kakhulu.
Izimo ezishisayo. Izinzwa zomhlanga zisebenza kangcono emazingeni okushisa ashisa kakhulu noma abandayo, kuyilapho izinzwa ze-Hall Effect zivame ukuba nezinkinga zokusebenza ezingeni lokushisa elidlulele.
