Inzwa yoxinzelelo 31Q4-40820 ilungele iindawo zangoku zokumba

Itransducer yoxinzelelo

Inzwa yoxinzelelo isetyenziselwa ukufumanisa uxinzelelo olubi lwesilinda, uxinzelelo lwe-atmospheric, i-bout ratio ye-injini ye-turbine, i-cylinder yangaphakathi yoxinzelelo kunye noxinzelelo lweoyile. Isivamvo soxinzelelo esibi sokufunxa sisetyenziswa ikakhulu ukubona uxinzelelo lokufunxa, uxinzelelo olubi kunye noxinzelelo lweoyile. I-Capacitance, i-piezoresistance, i-transformer eyahlukileyo (i-LVDT) kunye ne-surface elastic wave (SAW) isetyenziswa ngokubanzi kwiinzwa zoxinzelelo lwemoto.

I-sensor ye-capacitive ye-capacitive isetyenziselwa ukufumanisa uxinzelelo olubi, uxinzelelo lwe-hydraulic kunye noxinzelelo lomoya, kunye noluhlu lokulinganisa lwe-20 ~ 100kPa, eneempawu zamandla aphezulu okufakwayo, ukuphendula okulungileyo okuguquguqukayo kunye nokuguquguquka okulungileyo kokusingqongileyo. Inzwa yoxinzelelo lwe-piezoresistive ichaphazeleka kakhulu ngubushushu, obufuna enye isiphaluka sembuyekezo yeqondo lokushisa, kodwa ifanelekile kwimveliso yobuninzi. Inzwa yoxinzelelo lwe-LVDT inemveliso enkulu, ekulula ukuyikhupha ngedijithali, kodwa ine-anti-interference engalunganga. Inzwa yoxinzelelo lwe-SAW ineempawu zomthamo omncinci, ubunzima obulula, ukusetyenziswa kwamandla aphantsi, ukuthembeka okuphezulu, uvakalelo oluphezulu, isisombululo esiphezulu, imveliso yedijithali, njl. .

Isivamvo sokuqukuqela

I-sensor yokuhamba isetyenziselwa ukulinganisa ukuhamba komoya kunye nokuhamba kwamafutha enjini. Umlinganiselo wokuhamba komoya usetyenziselwa inkqubo yokulawula injini ukumisela iimeko zokutsha, ukulawula umlinganiselo we-air-fuel, ukuqala, ukuvutha njalo njalo. Kukho iintlobo ezine zezivamvo zokuhamba komoya: i-rotary vane (uhlobo lwe-vane), uhlobo lwe-Carmen vortex, uhlobo locingo olushushu kunye nodidi lwefilimu eshushu. I-rotary vane air flowmeter inesakhiwo esilula kunye nokuchaneka komlinganiselo ophantsi, ngoko ke ukuhamba komoya okulinganisiweyo kufuna imbuyekezo yobushushu. I-Carmen vortex air flowmeter ayinazo iindawo ezihambayo, ezinovakalelo kunye nezichanekileyo, kwaye zifuna imbuyekezo yobushushu. I-Hot-wire air flowmeter inomlinganiselo ophezulu wokuchaneka kwaye ayifuni imbuyekezo yeqondo lokushisa, kodwa ichaphazeleka lula ngokubetha kwegesi kunye neengcingo eziphukileyo. I-hot-film ye-air flowmeter inomgaqo ofanayo wokulinganisa njenge-hot-wire air flowmeter, kodwa incinci ngobukhulu, ifanelekile kwimveliso yobuninzi kunye nexabiso eliphantsi. Iimpawu eziphambili zezobugcisa ze-sensor yokuhamba komoya zezi: uluhlu olusebenzayo ngu-0.11 ~ 103 m3 / min, ukushisa okusebenzayo ngu-40 ℃ ~ 120 ℃, kunye nokuchaneka ≤1%.

Inzwa ye-fuel flow sensor isetyenziselwa ukufumanisa ukuhamba kwamafutha, ngokukodwa kubandakanywa uhlobo lwevili lamanzi kunye nohlobo lwebhola ejikelezayo, kunye noluhlu oluguquguqukayo lwe-0 ~ 60kg / h, ubushushu obusebenzayo -40 ℃ ~ 120 ℃, ukuchaneka kwe-1% kunye nexesha lokuphendula le-< 10ms .
