Ubutaka Bwiza

Urashobora kutubwira byinshi kubyerekeye ingaruka zumunyu kubisubizo?Hoba hariho ubwoko bumwebumwe bwa capacitifike yuburyo bubiri bwa ion mubutaka?

Byaba byiza uramutse unyerekeje kumakuru yandi kuriyi.Nshishikajwe no gupima neza neza ubutaka.

Tekereza niba hari umuyoboro mwiza uzengurutse sensor (urugero, niba sensor yarinjijwe mubyuma byamazi ya gallium), byahuza ibyapa bya capacitori hamwe kugirango insulator imwe rukumbi hagati yabo yaba igifuniko cyoroshye kuri ikibaho.

Izi sensororo zihenze, zubatswe kuri chip 555, mubisanzwe zikorera kuri frequence muri mirongo ya kHz, iri hasi cyane kugirango ikureho ingaruka zumunyu ushonga.Irashobora kuba mike bihagije kugirango itere ibindi bibazo nka dielectric absorption, yigaragaza nka hystereze.

Menya ko ikibaho cya sensor mubyukuri mubushobozi hamwe nubutaka buringaniye bwubutaka, bumwe kuruhande.Urashobora kandi gukoresha electrode idafunze idafite igifuniko icyo aricyo cyose kugirango uhuze, ariko electrode izahita ishonga mubutaka.Gukoresha umurima w'amashanyarazi bizatera polarisiyasi mubutaka + ibidukikije byamazi.Uruhushya rugoye rupimwa nkigikorwa cyumuriro wamashanyarazi wakoreshejwe, bityo polarisiyasi yibikoresho ihora inyuma yumurima wamashanyarazi washyizweho.Mugihe inshuro zumurima washyizwe ziyongera murwego rwo hejuru rwa MHz, igice cyibitekerezo cyurwego rwa dielectric gihoraho kigabanuka cyane nkuko dipole polarisiyasi itagikurikira ihindagurika ryinshi ryumuriro wumuriro wamashanyarazi.

Munsi ya ~ 500 MHz, igice cyibitekerezo cya dielectric gihoraho cyiganjemo umunyu kandi, nkigisubizo, korohereza.Hejuru yiyi frequence, polarisation ya dipole izagabanuka cyane kandi muri rusange dielectric ihoraho bizaterwa nibirimo amazi.

Ibyuma byinshi byubucuruzi bikemura iki kibazo ukoresheje imirongo yo hasi no gukoresha umurongo wa kalibrasi kugirango ubare imitungo yubutaka ninshuro.
