Q: Kodi tingapewe bwanji sensa yamagetsi yowunikira yofalikira kuti isazindikire zinthu zakumbuyo zomwe zili kunja kwa malo ake owonera?
Yankho: Choyamba, tiyenera kutsimikizira ngati maziko omwe apezeka molakwika ali ndi mawonekedwe a "kuwala kwambiri".
Zinthu zakumbuyo zowunikira bwino kwambiri zimatha kusokoneza magwiridwe antchito a masensa owunikira bwino kwambiri. Zimayambitsa kuwunikira kolakwika, zomwe zimapangitsa kuti masensa aziwerenga molakwika. Kuphatikiza apo, kuwunikira bwino kwambiri kumatha kusokoneza masensa owunikira bwino kwambiri komanso kuwunikira kumbuyo pang'ono.

Q: Kudziwa kuchuluka kwa ma frequency ndi kusankha kwa sensa kutengera liwiro lozungulira
A: Mafupipafupi amatha kuwerengedwa pogwiritsa ntchito njira iyi: f(frequency) Hz = RPM / 60s * chiwerengero cha mano.
•Kusankha masensa kuyenera kuganizira kuchuluka kwa ma frequency owerengedwa komanso kukwera kwa dzino la giya.
Tchati Chofotokozera Nthawi Yobwerezabwereza
| Kuchuluka kwa nthawi | Kuzungulira (nthawi yoyankhira) |
| 1Hz | 1S |
| 1000Hz | 1ms |
| 500Hz | 2ms |
| 100Hz | 10ms |
Mafupipafupi Odziwika:
Pa masensa oyambitsa ndi operekera mphamvu, giya yowunikira iyenera kuyikidwa pa 1/2Sn (kuonetsetsa kuti mtunda pakati pa dzino lililonse ndi ≤ 1/2Sn). Gwiritsani ntchito chida choyesera pafupipafupi kuti muyese ndikulemba kuchuluka kwa pafupipafupi kwa 1 cycle pogwiritsa ntchito oscilloscope (kuti mutsimikizire kulondola, lembani kuchuluka kwa ma cycle 5 kenako muwerenge avareji). Iyenera kukwaniritsa zofunikira za 1.17 (ngati mtunda wogwirira ntchito (Sa) wa switch yoyandikira uli wochepera 10mm, turntable iyenera kukhala ndi ma target osachepera 10; ngati mtunda wogwirira ntchito ndi woposa 10mm, turntable iyenera kukhala ndi ma target osachepera 6).
Sensa yopangira mafupipafupi ya M12/M18/M30
Kuzindikira mtunda: 2mm, 4mm, 5mm, 8mm

Mtundu wa silinda wachitsulo wa M18, kutulutsa kwa NPN/PNP
Kuzindikira mtunda: 2mm
Digiri ya chitetezo IP67 (IEC)
, Mafupipafupi mpaka 25KHz
Q: Pamene sensa ya mulingo wa pipeline ikugwiritsidwa ntchito kuzindikira mulingo wamadzimadzi mu payipi, kuzindikira kumakhala kosakhazikika. Ndiyenera kuchita chiyani?
A: Choyamba, onani ngati palichizindikiro chomatira cha mbali imodzipa payipi. Ngati theka lokha la payipi lalembedwa, lingayambitse kusiyana kwa dielectric constant, zomwe zimapangitsa kuti payipiyo isagwire bwino ntchito pamene ikuzungulira.
Chokhazikika cha Dielectric:
Chokhazikika cha dielectric chimasonyeza kuthekera kwa dielectric kusunga mphamvu zamagetsi m'munda wamagetsi. Pazinthu za dielectric, chokhazikika cha dielectric chikakhala chotsika, chimakhala bwino kwambiri.
Chitsanzo:Madzi ali ndi dielectric constant ya 80, pomwe mapulasitiki nthawi zambiri amakhala ndi dielectric constant pakati pa 3 ndi 5. Dielectric constant imawonetsa polarization ya chinthu mumagetsi. Dielectric constant yapamwamba imasonyeza kuyankha kwamphamvu kumagetsi.
Kuzindikira mtunda: 6mm
Amatha kuzindikira zinthu zachitsulo ndi zinthu zosakhala zachitsulo, zomwe zimagwiritsidwa ntchito kwambiri.
Mafupipafupi oyankha mpaka 100Hz.
Kusintha mwachangu komanso molondola kwa kuzindikira ndi potentiometer yozungulira ma multi-turn.
Q: Kodi mungasankhe bwanji masensa kuti azindikire tinthu tating'onoting'ono mumakampani opanga ziweto?
A: Kupezeka kwa mipata pakati pa tinthu tating'onoting'ono mu chakudya cha granular kumachepetsa malo olumikizirana bwino ndi malo ozindikira, zomwe zimapangitsa kuti dielectric ikhale yochepa poyerekeza ndi chakudya cha ufa.
Zindikirani:Samalani ndi kuchuluka kwa chinyezi m'chakudya cha sensa panthawi yogwira ntchito. Kuchuluka kwa chinyezi m'chakudya kungayambitse kumamatira kwa nthawi yayitali pamwamba pa sensa, zomwe zimapangitsa kuti sensa ikhalebe yokhazikika.
