Inokodzera Cummins pressure sensor injini zvikamu 3408589

1.kind

Kune akawanda marudzi emamechanic sensors, senge resistance strain gauge pressure sensor, semiconductor strain gauge pressure sensor, piezoresistive pressure sensor, inductive pressure sensor, capacitive pressure sensor, resonant pressure sensor uye capacitive acceleration sensor. Asi iyo inonyanya kushandiswa ndeye piezoresistive pressure sensor, ine yakaderera zvakanyanya mutengo, yakanyanya kurongeka uye yakanaka mutsara maitiro.

2.pivotal role

Pressure sensors haisi kungoshandiswa zvakanyanya mukuyera kwekugadzira, asi zvakare inowanzoonekwa muhupenyu hwedu mazuva ano. Mota dzedu zhinji dzine ma sensors. Zvichida vanhu vazhinji vanoziva kuti mumotokari mune ma sensor sensors, asi kutaura zvazviri, kunewo ma sensors pamidhudhudhu yakajairika.

Simba remudhudhudhu rinobva mukupisa kweoiri mucylinder yepeturu injini. Kupisa kwakazara chete kunogona kupa simba rakanaka, uye kupisa kwakanaka kunofanirwa kuve nemamiriro matatu: musanganiswa wakanaka, kudzvanya kwakazara uye kudzima kwakaringana. Kunyangwe iyo EFI system inogona kunyatso kudzora chiyero chemhepo-mafuta mukati meiyo inodiwa renji inogadzirisa simba, hupfumi uye emission index yejini. Kudzora kweyemhepo-mafuta reshiyo yepetroli injini kunoitwa nekugadzirisa mafuta ekufambisa anoenderana nehuwandu hwemhepo yekudyara, saka kuyerwa kwechiyero chekuyerera kwemhepo kunokanganisa zvakananga kutonga kwechiyero chemhepo-mafuta.

3.chimiro chemukati

Iyo ine matrix zvinhu, simbi strain waya kana strain foil, pepa rekudzivirira rekudzivirira uye waya yekutungamirira kunze. Maererano nekushandiswa kwakasiyana-siyana, kukosha kwekupikisa kwekupikisa strain gauge inogona kugadzirwa nemugadziri, asi huwandu hwehuwandu hwekupikisa hunofanira kubhadharwa kune: kukosha kwekupikisa kuduku, uye inodiwa yekufambisa ikozvino yakakura zvikuru. Panguva imwecheteyo, kupisa kweiyo strain gauge inoita kuti tembiricha yayo ive yakanyanya. Kana ichishandiswa munzvimbo dzakasiyana siyana, kukosha kwekupokana kweiyo strain geji inoshanduka zvakanyanya, iyo yakabuda zero drift iri pachena, uye zero gadziriso yedunhu yakanyanya kuoma. Nekudaro, kuramba kwakakura kwazvo, iyo impedance yakakwira zvakanyanya, uye kugona kuramba kukanganiswa kwemagetsi ekunze hakuna kunaka. Kazhinji, ingangoita makumi emaeuro kusvika makumi ezviuru emaeuro.
