Oil sensing plug inoreva mafuta pressure sensor. Nheyo yacho ndeyokuti kana injini ichimhanya, mudziyo wekuyeresa wekumanikidza unoona kudzvanywa kwemafuta, woshandura chiratidzo chekumanikidza kuita chiratidzo chemagetsi, uye wochitumira kudunhu rekugadzirisa. Mushure mekukwidziridzwa kwemagetsi uye ikozvino kukwidziridzwa, iyo yakawedzera kudzvanywa siginecha yakabatana neoiri yekumanikidza geji kuburikidza nemutsara wechiratidzo.
Injini yeoiri pressure inoratidzwa nereshiyo yezvino pakati pemakoiri maviri mune inochinja mafuta pressure chiratidzo. Mushure mekukwidziridzwa kwemagetsi uye ikozvino kukwidziridzwa, chiratidzo chekumanikidza chinofananidzwa nearamu voltage yakaiswa muaramu wedunhu. Kana iyo alarm voltage yadzikira pane yearamu voltage, alarm yedunhu inoburitsa chiratidzo chealarm uye inovhenekera mwenje wealarm kuburikidza nemutsara wearamu.
Oiri pressure sensor chinhu chakakosha chekuona kudzvanywa kwemafuta einjini yemotokari. Izvo zviyero zvinobatsira kudzora kushanda kwakajairika kweinjini.
Iyo oiri inonzwa plug inoumbwa neyakakora firimu kumanikidza sensor chip, chiratidzo chekugadzirisa dunhu, imba, yakagadziriswa yedunhu bhodhi mudziyo uye maviri anotungamira (chiratidzo mutsara uye alarm mutsara). Iyo siginecha yekugadzira dhizaini ine dhizaini yemagetsi, sensor compensation circuit, zerosetting circuit, voltage amplifying circuit, ikozvino amplifying circuit, filter circuit uye alarm circuit.
