Kuyini "ukushayela okufudumele"?
Ngaphansi kokuphazanyiswa kwezinto zangaphandle, umphumela wenzwa uvame ukuguqula ngokungadingekile, okungokuzimele kokufakwayo. Lolu hlobo lwenguquko lubizwa nge- "Temperature Drift", futhi i-Drift idalwa ikakhulukazi yinto yokuzwela yohlelo lokulinganisa, okuvame ukuba sengozini yokushisa kwangaphandle, umswakama, ukuphazamiseka kwe-electromagnete kanye nesifunda se-sensor soover. Ukushisa okuthe xaxa okuzoxoxwa ngakho namuhla kubhekisa kuzinguquko ze-semiconductor yamapharamitha amahle abangelwa izinguquko zokushisa.
Kungani kufaneleinzwa yokucindezelaYiba nokushisa okunxeshezelwe
Ngezinzwa ze-Silicon Pressus Sensor, ukuguqulwa kwe-silicon yokuphikiswa okubangelwa ukuguqulwa kwezinga lokushisa endaweni yokulinganisa kucishe kube yi-oda lokulinganisa elifanayo njengoba kushintsha ubunzima bokuvunyelwa kokulinganisa. Ukwethulwa kwephutha lokushisa kuthinta ngqo ukunemba kwemiphumela yokulinganisa, ngokuqondile: Ukukhishwa kwamandla okusebenza kwendawo yokusebenza ye-static ye-static yokusebenza kwengcindezelo yengculazi ngenxa yokushintsha okulinganiselwe kwe-medium ephakathi ngenxa yokushisa okulinganiselwe. Ngakho-ke, isinxephezelo sokushisa siyadingeka.
Ungayilawula kanjani into ethi "lokushisa"?
Ukuze uthole ukushisa kwenzwa yengcindezi, kuyadingeka ukuthi ukhethe indlela efanelekile yokunxephezela ukulawula i-drift yokushisa esekelwe ngenxa yezizathu ezithile. Izindlela ezisetshenziswa kaningi zihlukaniswe ikakhulu kwindlela yokunxephezelwa kwe-Hardware nendlela yokunxeshezelwa isoftware. I-Microphone Sensor isebenzisa indlela yokunxeshezelwa kwe-Hardware ukulinganisa i-zero drift ebangelwa ukungafani kwamanani okuqala we-silicon armicon kanye nokuxhumeka okufanayo kwenani elithile lokumelana nezingalo ezine zebhuloho ezihambisanayo ezakha ibhuloho le-Wheathstone.
