Oyenera Dongfeng Cummins mafuta kuthamanga sensa 4921489

1. Kodi sensor ya pressure ndi chiyani?

Sensor pressure ndi chipangizo chilichonse chomwe chimazindikira kukakamizidwa komwe kumachitika ndi chinthu kapena thupi. Kuchuluka kwa kupanikizika kwa chipangizocho kungathe kuwerengedwa ndi mphamvu yake pa sensa. Zomverera zimatha kukhala digito kapena analogi, koma mwanjira iliyonse, zimatha kutumiza chizindikiro chowerengera cha mtengo wapakatikati kudera lakutali.

Mawu oti "sensa" alinso liwu wamba komanso wamba kumlingo wina, kuphatikiza zida zenizeni, monga ma transducer ndi ma transmitters. Mwa kuyankhula kwina, ngakhale ma transducers onse othamanga ndi masensa, si onse omwe ali ndi mphamvu zowonongeka. Mukhozanso kutchula zigawo zoyezera zomwe zimakhudzidwa mwachindunji ndi kukakamizidwa monga "zomverera", osati zigawo zodziyimira pawokha zomwe zimasintha chidziwitsochi kukhala zizindikiro zamagetsi.

2. Kodi sensor ya pressure imagwira ntchito bwanji?

Monga chipangizo cha electromechanical, sensor pressure imatha kuzindikira ndikuwunika kuthamanga kwamadzimadzi potembenuza mphamvu yakuthupi pa chipangizocho kukhala chizindikiro chamagetsi.

Sensa yovuta yamagetsi ndi gawo la dongosolo lalikulu, lomwe silimangowerenga kuchuluka kwa kupanikizika komwe kumagwiritsidwa ntchito mu dongosolo, koma kwenikweni ndi udindo woyang'anira ndi kuyang'anira dongosolo poyankha kupanikizika komwe kumapezeka. Ndi kusintha kwa kuthamanga, kutulutsa kwa chizindikiro kwa sensa kudzasinthanso. Izi zitha kuyambitsa maulamuliro okonzedweratu kuyatsa, kuzimitsa kapena kusintha kuchuluka kwa zida zamakina pazigawo zina zomwe zadziwika.

3. Kodi transducer ya pressure ndi chiyani?

Pressure transducer ndi mtundu wa sensor yokakamiza, yomwe imapangidwa ndi chinthu chovuta kwambiri komanso chosinthira ma sign. Transducer imatembenuza siginecha yamagetsi yapakatikati kuchokera pamakina olowera (kuchokera ku gasi kapena madzi) kukhala voteji yofananira kapena kutulutsa kwa milliampere. "Transduction" amatanthauza "kusintha".

4. Kodi ntchito ya pressure transducer ndi yotani?

Transducer amawerenga kuthamanga kwa madzimadzi. Kenako, mphamvu yamagetsi kapena yaposachedwa ya transducer imatha kutumizidwa kudera lakutali kuti iwunikire ndikudziwitsa kuwongolera kwadongosolo kapena pamanja. Mitundu yotulutsa analogi imaphatikizapo: 4–20 mA, 0–5 VDC, 0–10 VDC, 1Vac kapena 0.333Vac. Ngati mugwiritsa ntchito digito pressure transducer (AKA pressure transmitter), zida zamagetsi zotsogola zitha kupereka ntchito yotumizira ma siginecha kudzera munjira zolumikizirana zama mafakitale monga Modbus kapena BACnet.

5. Ma transducers owuma ndi onyowa

Mpweya wowuma wowuma umayesa kusiyana kwapakati pa malo owuma (monga mpweya kapena mpweya wa mapaipi), pamene chotulutsa chonyowa chonyowa chimalola kuti munthu azimva kupanikizika m'njira yonyowa (monga mapaipi).
