Fuel pressure sensor 3083716 yeDongfeng mota yekuchera

Pressure sensor mudziyo une pressure sensitive elements, inoyera kudzvanywa kwegasi kana mvura kuburikidza nediaphragm yakagadzirwa nesimbi isina tsvina nesilicon. Paunenge uchishandisa kudzvanywa sensor, mamwe matambudziko anozoonekwa senge ruzha. Chii chinokonzera ruzha? Izvi zvinogona kunge zvichikonzerwa nekusaenderera mberi kwemukati conductive particles, kana pfuti ruzha rwunogadzirwa nemichina semiconductor. Zvimwe zvikonzero zvichatsanangurwa zvakadzama pasi apa.

Zvikonzero zveruzha mukumanikidza sensor

1. Iyo yakaderera-frequency ruzha rwekumanikidza sensor inonyanya kukonzerwa nekurega kwemukati conductive particles. Kunyanya kune kabhoni firimu kuramba, kazhinji kune akawanda madiki madiki mune kabhoni zvinhu, uye zvimedu zvinoramba. Mukuita kwekuyerera kwemazuva ano, iyo conductivity yeinopesana ichachinja, uye ikozvino ichachinjawo, zvichiita kuti flash arc yakafanana nekushaya kushamwaridzana.

2. Ruzha rwakapararira rwechikamu chinogadzirwa nemidziyo ye semiconductor inonyanya kukonzerwa nekushandurwa kwevoltage munzvimbo inovharira pamigumo yese ye semiconductor PN junction, iyo inotungamira kushanduko yechaji yakaunganidzwa munharaunda ino, nekudaro kuratidza pesvedzero ye capacitance. Kana mhepo yakananga yadzikira, dunhu rekuderera kwema electrons nemakomba rinowedzera, izvo zvakaenzana ne capacitor discharge.

3. Kana iyo reverse voltage inoshandiswa, nzvimbo yekuderedza inoshanduka kune imwe nzira. Apo ikozvino inoyerera kuburikidza nenharaunda yezvipingamupinyi, shanduko iyi ichaita kuti ikozvino inoyerera kuburikidza nenharaunda yezvipingamupinyi ichinje zvishoma, zvichiita kuti iite ruzha rwezvino. Kazhinji, mumagetsi emagetsi pane inomanikidza sensor redunhu bhodhi, kana paine kukanganisa, mazhinji edunhu mabhodhi ane emagetsi magineti senge relay uye coils. Mukuita kwekuyerera kwezvino kuyerera, inductance yecoil uye capacitance yakagoverwa yegoko inopenya simba kunzvimbo iri pedyo. Simba richakanganisa matunhu ari pedyo.

4. Shanda kakawanda semarelay uye zvimwe zvikamu. Simba-pa uye simba-kudzima rinoburitsa pakarepo reverse yakakwira voltage uye nekukasira kuvhiya ikozvino. Iyi instantly high voltage ichave nekukanganisa kukuru padunhu, izvo zvinozokanganisa zvakanyanya basa rakajairwa remagetsi. Circuit.
