Inokodzera Dongfeng Cummins oiri pressure sensor 4921489

1. Chii chinonzi pressure sensor?

A pressure sensor chero mudziyo unoona kudzvanywa kunoitwa pairi nechinhu kana muviri. Huwandu hwekumanikidza pachigadzirwa hunogona kuverengerwa nesimba rayo pane sensor. Masensa anogona kuve edhijitari kana analog, asi neimwe nzira, anogona kutumira chiratidzo chekuverenga cheiyo chaiyo yekumanikidza kukosha kunzvimbo iri kure.

Izwi rekuti "sensor" ishoko rakajairwa uye rakajairwa kusvika pamwero wakati, kusanganisira zvimwe midziyo chaiyo, senge transducer uye transmitters. Mune mamwe mazwi, kunyangwe ese ma-pressure transducers ari ma sensors, haasi ese ma sensors ekumanikidza ari transducers. Iwe unogona zvakare kutaura kune yekuyera sisitimu zvikamu zvakakanganiswa zvakananga nekumanikidza se "sensors", pane yakazvimirira zvikamu zveiyo system inoshandura ruzivo urwu kuita masaini emagetsi.

2. Ko iyo yekumanikidza sensor inoshanda sei?

Sechigadzirwa che electromechanical, iyo sensor yekumanikidza inogona kuona uye kutarisa kudzvanywa muhurongwa hwemvura nekushandura simba remuviri pane mudziyo kuita chiratidzo chemagetsi.

Iyo yakaoma yekumanikidza sensor chikamu cheiyo yakakura sisitimu, iyo isingaverenge chete iyo yekumanikidza nhanho inoshandiswa muhurongwa, asi inonyatso ibasa rekutarisa nekudzora sisitimu mukupindura kune yakaonekwa yekumanikidza level. Nekuchinja kwekumanikidza, chiratidzo chinobuda che sensor chichachinjawo. Izvi zvinogona kukonzeresa zvidzoreso zvakagadzirirwa kubatidza, kudzima kana kugadzirisa nhanho yezvikamu zvehurongwa pane dzimwe nzvimbo dzakaonekwa.

3. Chii chinonzi pressure transducer?

Pressure transducer imhando yepressure sensor, iyo inoumbwa neiyo pressure sensitive element uye chiratidzo chekushandura chinhu. Iyo transducer inoshandura yakaderera-level yemagetsi siginecha kubva pakupinza mechanical pressure (kubva gasi kana mvura) kuita proportional voltage kana milliampere kubuda. "Transduction" zvinoreva "shanduko".

4. Chii chinoshanda chepressure transducer?

Transducer inoverenga kudzvanywa kwemvura. Zvadaro, iyo voltage kana yazvino kubuda kweiyo transducer inogona kuendeswa kunzvimbo iri kure yekutarisa uye kuzivisa iyo otomatiki kana yemanyorero kutonga kwehurongwa. Mhando dzeanalogi dzinobuda dzinosanganisira: 4–20 mA, 0–5 VDC, 0–10 VDC, 1Vac kana 0.333Vac. Kana iwe ukashandisa dhijitari pressure transducer (AKA pressure transmitter), yakawedzera kugadzirwa zvemagetsi zvinogona kupa basa rekutumira masaini kuburikidza nemaindasitiri ekutaurirana mapuroteni akadai seModbus kana BACnet.

5. Dry and wet pressure transducers

A dry pressure transducer inoyera mutsauko wekumanikidza munzvimbo yakaoma (yakadai semhepo kana gasi pombi system), nepo inonyorovesa yepakati pressure transducer inobvumira kunzwa kudzvanywa muhunyoro (senge pombi).
