Pressure sensor 31Q4-40820 yoyenera zida zamakono zakufukula

Pressure transducer

The pressure sensa makamaka ntchito kudziwa yamphamvu zoipa, kuthamanga mumlengalenga, kulimbikitsa chiŵerengero cha turbine injini, yamphamvu mkati kuthamanga ndi kuthamanga mafuta. The suction negative pressure sensor imagwiritsidwa ntchito kwambiri kuti izindikire kuthamanga kwamphamvu, kupanikizika koyipa komanso kuthamanga kwamafuta. Capacitance, piezoresistance, differential transformer (LVDT) ndi surface elastic wave (SAW) amagwiritsidwa ntchito kwambiri pamasensi amagetsi agalimoto.

Capacitive pressure sensor imagwiritsidwa ntchito kwambiri pozindikira kupanikizika koyipa, kuthamanga kwa hydraulic ndi kuthamanga kwa mpweya, komwe kumakhala ndi 20 ~ 100kPa, yomwe ili ndi mawonekedwe amphamvu yolowera, kuyankha kwamphamvu komanso kusinthasintha kwachilengedwe. Piezoresistive pressure sensor sensor imakhudzidwa kwambiri ndi kutentha, komwe kumafuna dera lina lolipirira kutentha, koma ndiloyenera kupanga misa. LVDT pressure sensor ili ndi zotulutsa zazikulu, zomwe ndizosavuta kutulutsa digito, koma zimakhala ndi zotsutsana ndi zosokoneza. SAW pressure sensor ili ndi mawonekedwe a voliyumu yaying'ono, kulemera kopepuka, kugwiritsa ntchito mphamvu zochepa, kudalirika kwakukulu, kukhudzika kwakukulu, kusamvana kwakukulu, kutulutsa kwa digito, ndi zina zambiri. Ndi sensor yabwino kwambiri yozindikira kuthamanga kwa valavu yotengera galimoto ndipo imatha kugwira ntchito mokhazikika pakutentha kwambiri. .

Sensa yoyenda

Sensa yothamanga imagwiritsidwa ntchito makamaka kuyeza kayendedwe ka mpweya ndi kayendedwe ka mafuta a injini. Kuyeza kwa mpweya kumagwiritsidwa ntchito poyang'anira injini kuti adziwe momwe kuyaka, kuwongolera mpweya ndi mafuta, chiyambi, kuyatsa ndi zina zotero. Pali mitundu inayi ya masensa akuyenda kwa mpweya: rotary vane (mtundu wa vane), mtundu wa Carmen vortex, mtundu wa waya wotentha ndi mtundu wa filimu yotentha. The rotary vane air flowmeter ili ndi mawonekedwe osavuta komanso ocheperako muyeso, kotero kuyeza kwa mpweya kumafunika kulipidwa kutentha. Carmen vortex air flowmeter ilibe zigawo zosuntha, zomwe zimakhala zomveka komanso zolondola, komanso zimafunikira chipukuta misozi. Hot-waya mpweya flowmeter ali mkulu muyeso molondola ndipo safuna chipukuta misozi kutentha, koma amakhudzidwa mosavuta ndi mpweya pulsation ndi mawaya osweka. Mpweya wotentha wa filimu yotentha uli ndi mfundo yoyezera yofanana ndi mpweya wotentha wa waya, koma ndi yaying'ono mu kukula, yoyenera kupanga misala komanso yotsika mtengo. Zizindikiro zazikulu zaukadaulo wa sensa ya mpweya ndi: gawo logwira ntchito ndi 0.11 ~ 103 m3 / min, kutentha kwa ntchito ndi -40 ℃ ~ 120 ℃, ndipo kulondola ndi ≤1%.

Mafuta otaya kachipangizo ntchito kudziwa otaya mafuta, makamaka kuphatikizapo madzi gudumu mtundu ndi kuzungulira mpira mtundu, ndi zazikulu osiyanasiyana 0 ~ 60kg/h, ntchito kutentha kwa -40 ℃ ~ 120 ℃, kulondola kwa 1% ndi nthawi poyankha <10ms .
