Bikwiranye na Cummins L10 N14 M11 sensor ya peteroli 4921485

Ubushobozi bwa sensor sensor

1.Capacitive position sensor ni sensor idahuza sensor, ubusanzwe igizwe nibice bitatu: ahantu hagaragara, urwego rukingira hamwe nigikonoshwa. Barashobora gupima neza neza intego, ariko ikintu gusa. Niba ikintu cyapimwe kitayobora, biracyakenewe gupima ubunini bwacyo cyangwa ubucucike.

2.Iyo gupima ikintu kiyobora, ibimenyetso bisohoka ntaho bihuriye nibikoresho byikintu, kuko kuri sensor ya capacitive displacement sensor, abayobora bose ni electrode imwe. Ubu bwoko bwa sensor bukoreshwa cyane cyane muri disiki ya disiki, tekinoroji ya semiconductor hamwe no gupima inganda zisobanutse neza, ariko bisaba ubunyangamugayo buhanitse kandi bwihuse. Iyo ikoreshwa mugupima abatayobora, sensor ya positif ya positif isanzwe ikoreshwa mugutahura ibirango, ibifuniko no gupima ubunini bwimpapuro cyangwa firime.

3.Capacitive position sensor yakoreshejwe muburyo bwo gupima intera yo kwimura umurongo, kuva kuri milimetero nyinshi kugeza kuri nanometero nyinshi, kandi gupima byarangiye hakoreshejwe amashanyarazi aranga amashanyarazi. Ubushobozi bwikintu cyo kubika amafaranga bita capacitance. Igikoresho gisanzwe cyo kubika amafaranga ni capacitori. Ubushobozi bwa plaque capacitor irahwanye neza na electrode hamwe na dielectric ihoraho, kandi igereranya intera iri hagati ya electrode. Kubwibyo, iyo intera iri hagati ya electrode ihinduka, ubushobozi nabwo burahinduka. Mu ijambo, ubushobozi bwimyanya sensor ikoresha iyi miterere kugirango yuzuze imyanya.

4.Ubusanzwe busanzwe bwa capacitive position sensor ikubiyemo ibyuma bibiri bya electrode, hamwe numwuka nka dielectric. Electrode imwe ya sensor ni isahani yicyuma, indi electrode ya capacitor igizwe nibintu byayobora bigomba kumenyekana. Iyo voltage ikoreshejwe hagati yamasahani yuyobora, hashyirwaho umurima wamashanyarazi hagati yamasahani, kandi amasahani abiri abika ibintu byiza hamwe nuburyo bubi. Ubushobozi bwa sensor capacitif busanzwe bukoresha AC voltage, ituma amafaranga yishyurwa ahinduranya polarite buri gihe, bityo ihinduka ryintego rishobora kugaragara mugupima ubushobozi buri hagati yibyapa byombi.

5.Ubushobozi bugenwa nintera iri hagati yamasahani, dielectric ihoraho ya dielectric nintera iri hagati yamasahani. Mubyuma byinshi, agace hamwe na dielectric ihoraho ya plaque ya electrode ntabwo bizahinduka, gusa intera izagira ingaruka kubushobozi buri hagati ya electrode nikintu cyerekanwe. Kubwibyo, ihinduka rya capacitance rirashobora kwerekana intego igenewe. Binyuze muri kalibibasi, ibisohoka voltage ibimenyetso bya sensor bifite isano ifitanye isano nintera iri hagati yikibaho cyo kumenya. Ubu ni sensibilité ya sensor. Irerekana ikigereranyo cyibisohoka voltage ihinduka kumwanya uhinduka. Igice mubisanzwe ni 1V / micron, ni ukuvuga, ibisohoka voltage ihinduka 1V buri microne 100.

6.Iyo umuyaga ushyizwe mumwanya wo gutahura, hazakorwa umurima w'amashanyarazi ukwirakwizwa kubintu byagaragaye. Kugirango ugabanye kwivanga, hiyongereyeho urwego rwo gukingira. Ikoresha ingufu za electromotive imwe kumpande zombi zahantu hagaragara kugirango irinde amashanyarazi mumwanya wo gutahura. Abayobora hanze y’ahandi hantu hamenyekana bazakora umurima wamashanyarazi hamwe nuburinzi kandi ntibazabangamira umurima wamashanyarazi hagati yintego n’ahantu ho gutahura. Bitewe nurwego rwo gukingira, umurima wamashanyarazi mugace kamenyekanye ni conic. Agace kateganijwe kumurima wamashanyarazi kasohowe na electrode yo gutahura ni 30% kuruta agace kamenyekanye. Kubwibyo, umurambararo wa diameter yikintu cyamenyekanye ugomba kuba byibuze byibuze 30% ugereranije n’ahantu hagaragara.
