P: Re ka thibela sensor ea "diffuse reflection photoelectric sensor" joang hore e se ke ea lemoha lintho tse ka morao ka ntle ho sebaka sa eona sa kutlo?
K: E le mohato oa pele, re lokela ho netefatsa hore na bokapele bo fumanoeng ka phoso bo na le thepa ea "khanya e phahameng".
Lintho tse ka morao tse khanyang tse phahameng li ka kena-kenana le ts'ebetso ea li-sensor tsa photoelectric tsa diffuse reflection. Li baka maikutlo a fosahetseng, a lebisang ho ballo e fosahetseng ea sensor. Ho feta moo, li-backlights tse khanyang tse phahameng li ka kena-kenana le li-sensor tsa photoelectric tse sa bonahaleng le tse hatellang ka morao ho isa bohōleng bo itseng.

P: Ha sensor ea boemo ba lipeipi e sebelisoa ho bona boemo ba mokelikeli ka har'a hose, kutlo ha e tsitsa. Ke etseng?
A: Pele, hlahloba hore na ho na leleibole la sekgomaretsi se ka mahlakoreng a halofoka hose. Haeba halofo feela ea hose e ngotsoe, e tla baka phapang pakeng tsa dielectric constant, e leng se tla fella ka kutlo e sa tsitsang ha hose e ntse e potoloha.
Dielectric Constant:
Dielectric constant e bontsha bokgoni bo lekanyeditsweng ba dielectric material ho boloka matla a electrostatic lebaleng la motlakase. Bakeng sa lisebelisoa tsa dielectric, ho theola sekhahla sa dielectric se lekanyelitsoeng, ho kenya letsoho ho betere.
Mohlala:Metsi a na le dielectric constant tsa 80, athe dipolasetiki ka tlwaelo di na le dielectric constant between 3 le 5. Dielectric constant e bontsha polarization ya thepa lebaleng la motlakase. Nako e phahameng ea dielectric kamehla e bontša karabelo e matla holima motlakase.
Sebaka sa ho lemoha: 6mm
E khona ho lemoha lintho tsa tšepe le tseo e seng tsa tšepe, tse sebelisoang haholo.
Khafetsa ea karabo ho fihla ho 100Hz.
Litokiso tse potlakileng le tse nepahetseng tsa kutlo ka potentiometer ea li-multi-turn.
P: U ka khetha li-sensor joang bakeng sa ho lemoha lijo tsa likaroloana indastering ea mehlape?
A: Ho ba teng ha likheo pakeng tsa likaroloana tsa motho ka mong lijong tsa granular ho fokotsa sebaka se sebetsang sa ho kopana le bokaholimo ba kutlo, ho fella ka thepa e tlase ea dielectric ha e bapisoa le phepelo ea phofshoana.
Hlokomela:Ela hloko boemo ba mongobo oa phepelo nakong ea ts'ebetso ea sensor. Mongobo o feteletseng ho fepa o ka lebisa ho khomarela nako e telele sebakeng sa sensor, ho etsa hore sensor e lule e le boemong bo tsitsitseng.
