Ogeysiis (wax ka qabashada)
• Ha ku dabaqin eexda DC ee buzzerka piezoelectric;haddii kale caabbinta dahaarka ayaa laga yaabaa inay hoos u dhacdo oo saameynayso waxqabadka.
• Ha siin wax danab ah oo ka sarreeya kan lagu dabaqi karo buzzer-ka korontada ee piezo.
• Ha isticmaalin buzzer-ka piezoelectric dibadda.Waxaa loogu talagalay isticmaalka gudaha.Haddii buzzer-ka piezoelectric ay tahay in lagu isticmaalo bannaanka, sii tallaabooyinka ilaalinta biyaha;si caadi ah uma shaqayn doonto haddii qoyaan lagu sameeyo.
• Ha ku dhaqin buzzer-ka piezoelectric dareere ama ha u ogolaan gaas inuu galo markaad dhaqayso;dareere kasta oo gala waxa laga yaabaa inuu gudaha ku jiro wakhti dheer oo uu dhaawaco.
• Qalabka dhoobada ah ee loo yaqaan 'piezoelectric ceramics' oo dhumucdiisu tahay 100µm ayaa loo isticmaalaa koronto dhaliyaha dhawaaqa.Ha ku cadaadin kicinta codka gudaha daloolka sii daynta codka haddii kale waxa laga yaabaa in alaabta dhoobada ahi jabto.Ha ku rarin buzzers piezoelectric adoon xidhin.
Ha ku isticmaalin wax xoog makaanik ah buzzer-ka piezoelectric;haddii kale kiisku wuu isbedeli karaa oo wuxuu keeni karaa hawl-gal aan habboonayn.
Ha dhigin shay gaashaan ama wax la mid ah hortiisa daloolka dhawaaqa sii daynta ee buzzer;Haddii kale cadaadiska sanqadhigu wuu kala duwanaan karaa oo wuxuu keenaa hawl-qabad aan degganayn.Hubi in qeylo-dhaanta aysan saameyn ku yeelan mowjadda taagan ama wax la mid ah.
Hubi inaad ku iibiso terminalka buzzer-ka ugu badnaan 350°C
• Ka fogow isticmaalka buzzer-ka piezoelectric muddo dheer halkaasoo gaas kasta oo daxalaysa (H2S, iwm.) uu jiro;Haddii kale qaybaha ama koronto-dhaliyaha codka ayaa laga yaabaa inay daxaloobaan oo ay keenaan hawl-gal aan habboonayn.
Ka taxadar inaadan tuurin buzzer-ka piezoelectric.
