Pressure sensor 31Q4-40820 inokodzera zvikamu zvemazuva ano zvekuchera

Pressure transducer

Iyo pressure sensor inonyanya kushandiswa kuona cylinder negative pressure, atmospheric pressure, boost ratio yeinjini yeturbine, silinda yemukati kumanikidza uye kudzvanywa kwemafuta. Iyo suction negative pressure sensor inonyanya kushandiswa kuona kusveta kudzvanywa, kudzvanywa kwakashata uye kudzvanywa kwemafuta. Capacitance, piezoresistance, differential transformer (LVDT) uye pamusoro elastic wave (SAW) anoshandiswa zvakanyanya mumotokari kumanikidza sensors.

Capacitive pressure sensor inonyanya kushandiswa kuona kudzvinyirira kwakashata, hydraulic pressure uye air pressure, ine chiyero chekuyera che 20 ~ 100kPa, iyo ine hunhu hwepamusoro pekuisa simba, mhinduro yakanaka ine simba uye yakanaka kugadzirisa kwezvakatipoteredza. Piezoresistive pressure sensor inopesvedzerwa zvakanyanya netembiricha, iyo inoda imwe tembiricha muripo wedunhu, asi yakakodzera kugadzirwa kwemazhinji. LVDT pressure sensor ine yakakura yakabuda, iri nyore kuburitsa digitally, asi ine urombo anti-kupindira. SAW pressure sensor ine hunhu hwevhoriyamu diki, huremu huremu, kuderera kwesimba rekushandisa, kuvimbika kwepamusoro, kunzwisiswa kwepamusoro, kugadziriswa kwepamusoro, kubuda kwedhijitari, nezvimwe. Iyo i sensor yakanaka yekuona kudzvanywa kwevhavha yekutora mota uye inogona kushanda zvakatsiga pakupisa kwakanyanya. .

Kuyerera sensor

Iyo yekuyerera sensor inonyanya kushandiswa kuyera kuyerera kwemhepo uye kuyerera kwemafuta einjini. Chiyero chekuyerera kwemhepo chinoshandiswa kune injini yekudzora system kuona mamiriro ekupisa, kudzora mhepo-mafuta reshiyo, kutanga, kubatidza uye zvichingodaro. Kune marudzi mana emasensa ekuyerera kwemhepo: rotary vane (vane type), Carmen vortex type, hot wire type uye hot film type. Iyo rotary vane air flowmeter ine chimiro chakareruka uye yakaderera kuyerwa kwechiyero, saka kuyerwa kwemhepo kuyerera kunoda muripo wetembiricha. Carmen vortex air flowmeter haina zvikamu zvinofamba, izvo zvinonzwisisika uye zvakarurama, uye zvinodawo muripo wekushisa. Kupisa-waya mhepo inoyerera ine yakakwirira kuyerwa kwakaringana uye haidi muripo wetembiricha, asi inokanganiswa nyore negasi pulsation uye waya dzakatyoka. Iyo inopisa-yefirimu air flowmeter ine imwechete yekuyera musimboti seyakapisa-waya air flowmeter, asi idiki muhukuru, yakakodzera kugadzirwa kwemazhinji uye yakaderera mumutengo. Iyo huru tekinoroji zviratidzo zvemhepo inoyerera sensor ndeiyi: iyo yekushanda siyana ndeye 0.11 ~ 103 m3 / min, tembiricha yekushanda ndeye -40 ℃ ~ 120 ℃, uye iko kurongeka kuri ≤1%.

Fuel flow flow sensor inoshandiswa kuona kuyerera kwemafuta, kunyanya kusanganisira rudzi rwevhiri remvura uye rudzi rwebhora rinotenderera, rine simba re 0 ~ 60kg/h, tembiricha yekushanda ye -40 ℃ ~ 120 ℃, kunyatsoita 1% uye nguva yekupindura ye <10ms. .
