Excavator pressure sensor ndiyo inonyanya kushandiswa sensor, iri izwi rakajairika rekuona gasi, mvura, yakasimba uye zvimwe zvinhu pakati peiyo inductive simba simba, inosanganisirawo.
Manometers anoyera pressure yemhepo kumusoro nemavacuum geji anoyera mhepo iri pazasi. Kune akawanda marudzi efosi sensor, iyo yechinyakare yekuyera nzira ndeyekushandisa deformation uye kutamiswa kwezvinhu elastic kuratidza kuchengetedzwa kwemagetsi jekiseni injini, asi huwandu hwayo hwakakura, hwakashata, uye kubuda hakuna mutsara. Nekukura kwehunyanzvi hwemakroelectronics, kushandisa semiconductor zvinhu piezoresistive mhedzisiro uye yakakwira elasticity, kusimudzira semiconductor simba sensors, yakakosha silicon piezoresistive uye capacitive maviri, vane diki diki, huremu huremu, hukuru hwekunzwa zvakanaka, hunoshandiswa zvakanyanya mu semiconductor simba. sensors. Kana semiconductor yakasimbiswa kumusoro pamusoro pekristaro, resistivity yayo ichachinja. Hukama huri pakati peiyo conductor resistivity shanduko uye kushushikana kunonzi semiconductor piezoresistive effect, uye iyo mechanic quantity sensor yakagadzirwa neichi chiitiko inonzi piezoresistive force sensor, ine marudzi maviri, imwe inzwa inogadzirwa neye semiconductor strain gauge yakaiswa pa elastic element, inonzi pasted piezoresistive sensor. Imwe yacho ndeyekupararira kwekudzivirira kunogadzirwa neyakasanganiswa yedunhu tekinoroji pane iyo substrate ye semiconductor zvinhu, kuitira kuti iyo strain geji uye iyo silicon substrate iumbe yakafanana sensor yese, inonzi diffusion piezoresistive sensor. Iyo ine hunhu hwekunzwa kwakanyanya, kurongeka kwakanyanya, diki diki, huremu huremu, yakakwirira kushanda frequency, chimiro chakareruka, basa rakavimbika uye hupenyu hurefu.
