Q: Tingalepheretse bwanji sensa yowonetsera chithunzi chamagetsi kuti isazindikire monyenga zinthu zakumbuyo zomwe zili kunja kwa zomverera zake?
Yankho: Monga sitepe yoyamba, tiyenera kutsimikizira ngati maziko omwe apezeka molakwika ali ndi "chinyezimira chowala kwambiri".
Zinthu zowala kwambiri zonyezimira zimatha kusokoneza magwiridwe antchito a masensa owonetsa ma photoelectric. Amayambitsa zonyezimira zabodza, zomwe zimatsogolera ku kuwerenga kolakwika kwa sensa. Kuphatikiza apo, zowala zowoneka bwino zimathanso kusokoneza mawonedwe owoneka bwino komanso kupondereza kumbuyo kwa ma sensor a photoelectric mpaka pamlingo wina.

Q: Kutsimikiza kwa ma frequency ndi kusankha kwa sensa kutengera liwiro lozungulira
A: Mafupipafupi amatha kuwerengedwa pogwiritsa ntchito njira iyi: f (mafupipafupi) Hz = RPM / 60s * chiwerengero cha mano.
•Kusankha kwa sensa kuyenera kuganizira ma frequency owerengeka komanso kukwera kwa dzino kwa giya.
Tchati cholozera nthawi zambiri
| pafupipafupi | Cycle (nthawi yoyankha) |
| 1Hz pa | 1S |
| 1000Hz | 1ms |
| 500Hz | 2ms |
| 100Hz | 10ms |
Nthawi zambiri:
Kwa masensa ochititsa chidwi komanso opatsa mphamvu, zida zomwe mukufuna kuziyika ziyenera kuyikidwa pa 1/2Sn (kuwonetsetsa kuti mtunda pakati pa dzino lililonse ndi ≤ 1/2Sn). Gwiritsani ntchito ma frequency test fixture kuti muyese ndikulemba kuchuluka kwa ma frequency a 1 cycle pogwiritsa ntchito oscilloscope (kulondola, lembani ma frequency a 5 mizungu ndikuwerengera avareji). Iyenera kukwaniritsa zofunikira za 1.17 (ngati mtunda wogwiritsira ntchito mwadzina (Sa) wa chosinthira choyandikira ndi chochepera 10mm, turntable iyenera kukhala ndi zolinga zosachepera 10; ngati mtunda wogwiritsira ntchito mwadzina ndi waukulu kuposa 10mm, turntable iyenera kukhala ndi zolinga zosachepera 6).

Q: Pamene sensa ya mulingo wa mapaipi imagwiritsidwa ntchito kuti izindikire kuchuluka kwa madzi mu payipi, kumva kumakhala kosakhazikika. Kodi nditani?
A: Choyamba, onani ngati pali atheka-mbalimbali zomatira chizindikiropa hose. Ngati theka la payipi lalembedwa, lingayambitse kusiyana kwa dielectric constant, zomwe zimapangitsa kuti munthu asamve bwino pamene payipi imazungulira.
Dielectric Constant:
Kukhazikika kwa dielectric kumawonetsa kuthekera kwapang'onopang'ono kwa zida za dielectric kusunga mphamvu zamagetsi m'munda wamagetsi. Pazinthu za dielectric, kutsika kwa dielectric pafupipafupi, kumapangitsanso kutchinjiriza bwino.
Chitsanzo:Madzi ali ndi dielectric constant 80, pamene mapulasitiki amakhala ndi dielectric constant pakati pa 3 ndi 5. Dielectric constant imawonetsa polarization ya zinthu m'munda wamagetsi. Kuchuluka kwa dielectric nthawi zonse kumasonyeza kuyankha mwamphamvu kumunda wamagetsi.
Kuzindikira mtunda: 6mm
Amatha kuzindikira zinthu zachitsulo komanso zopanda zitsulo, zomwe zimagwiritsidwa ntchito kwambiri.
Kuyankha pafupipafupi mpaka 100Hz.
Kusintha kwachangu komanso kolondola kokhala ndi ma multi-turn potentiometer.
Q: Momwe mungasankhire masensa kuti muzindikire chakudya chamagulu m'makampani a ziweto?
A: Kukhalapo kwa mipata pakati pa tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono kumachepetsa malo olumikizana bwino ndi malo omvera, zomwe zimapangitsa kuti pakhale ma dielectric otsika poyerekeza ndi chakudya cha ufa.
Zindikirani:Samalani ndi chinyezi cha chakudya pakugwira ntchito kwa sensor. Kuchuluka kwa chinyezi m'zakudya kungayambitse kumamatira kwa nthawi yayitali kumtunda wa sensa, kuchititsa kuti sensa ikhalebe nthawi zonse.
