Q: Yuav ua li cas peb tuaj yeem tiv thaiv lub diffuse reflection photoelectric sensor los ntawm kev tsis pom cov khoom tom qab sab nraud ntawm nws qhov kev paub ntau yam?
A: Ua thawj kauj ruam, peb yuav tsum txheeb xyuas yog tias qhov tsis raug kuaj pom yav dhau los muaj "high-brightness reflective" khoom.
High-brightness reflective tom qab cov khoom tuaj yeem cuam tshuam nrog kev ua haujlwm ntawm diffuse reflection photoelectric sensors. Lawv ua rau cov kev xav tsis tseeb, ua rau cov ntawv nyeem tsis raug. Ntxiv mus, high-brightness reflective keeb kwm kuj tuaj yeem cuam tshuam nrog ob qho tib si diffuse reflection thiab keeb kwm kev tiv thaiv photoelectric sensors rau qee qhov.

Q: Kev txiav txim siab ntawm zaus thiab sensor xaiv raws li kev sib hloov ceev
A: Zaus tuaj yeem suav nrog cov qauv hauv qab no: f (frequency) Hz = RPM / 60s * tus lej ntawm cov hniav.
•Kev xaiv sensor yuav tsum xav txog ob qho tib si suav zaus thiab lub iav lub ntsej muag.
Frequency-Time Reference Chart
| Ntau zaus | Cycle (lub sij hawm teb) |
| 1 Hz | 1S |
| 1000 Hz | 1ms ib |
| 500 Hz | 2ms ib |
| 100 Hz | 10ms ib |
Nominal zaus:
Rau inductive thiab capacitive sensors, lub hom phiaj iav yuav tsum muab tso rau ntawm 1/2Sn (kom ntseeg tau tias qhov kev ncua deb ntawm txhua tus hniav yog ≤ 1/2Sn). Siv lub tshuab ntsuas zaus los ntsuas thiab sau cov nqi zaus ntawm 1 lub voj voog uas siv lub oscilloscope (rau qhov tseeb, sau qhov zaus ntawm 5 lub voj voog thiab tom qab ntawd xam qhov nruab nrab). Nws yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm 1.17 (yog tias qhov kev khiav hauj lwm deb (Sa) ntawm qhov sib thooj hloov yog tsawg dua 10 hli, lub turntable yuav tsum muaj tsawg kawg yog 10 lub hom phiaj; yog tias qhov kev khiav hauj lwm nominal ntau dua 10 hli, lub turntable yuav tsum muaj tsawg kawg yog 6 lub hom phiaj).

Q: Thaum lub raj xa dej ntsuas ntsuas tau siv los ntsuas cov kua theem hauv lub hose, qhov ntsuas tsis ruaj khov. Kuv yuav ua li cas?
A: Ua ntej, xyuas seb puas muajib nrab-sided nplaum daim ntawv lope cev. Yog tias tsuas yog ib nrab ntawm lub hose tau sau npe, nws yuav ua rau muaj qhov sib txawv ntawm dielectric tas li, ua rau tsis ruaj tsis khov thaum lub hose tig.
Dielectric tsis tu ncua:
Lub dielectric qhov tsis tu ncua qhia txog qhov muaj peev xwm ntawm cov khoom siv dielectric los khaws cov hluav taws xob hluav taws xob hauv hluav taws xob. Rau cov khoom siv dielectric, qhov qis dua qhov txheeb ze dielectric tas li, qhov zoo dua cov rwb thaiv tsev.
Piv txwv:Dej muaj qhov dielectric tas li ntawm 80, thaum cov yas feem ntau muaj qhov dielectric tas li ntawm 3 thiab 5. Qhov dielectric tas li qhia txog cov khoom siv polarization hauv qhov hluav taws xob. Qhov siab dua dielectric qhov tsis tu ncua qhia tias muaj zog teb rau qhov hluav taws xob.
Sensing nrug: 6mm
Nws tuaj yeem ntes cov khoom siv hlau thiab cov khoom tsis yog hlau, siv dav dua.
Teb zaus mus txog 100Hz.
Kev hloov pauv ceev thiab raug raug nrog ntau tig potentiometer.
Q: Yuav ua li cas xaiv sensors rau particle feed detection hauv kev lag luam tsiaj txhu?
A: Lub xub ntiag ntawm qhov sib txawv ntawm ib tus neeg nyob rau hauv granular pub txo qhov kev sib cuag zoo nrog qhov chaw hnov, ua rau qis dielectric zog piv rau cov hmoov pub.
Nco tseg:Ua tib zoo saib xyuas cov dej noo ntawm cov khoom noj thaum lub sijhawm ua haujlwm sensor. Cov dej noo ntau dhau ntawm cov khoom noj tuaj yeem ua rau lub sij hawm ntev adhesion rau lub sensor nto, ua rau lub sensor nyob twj ywm rau hauv lub xeev.
