RE542461 imagwiritsidwa ntchito pa sensor yamafuta a John Deere.

Zomverera zowongolera injini

Pali mitundu yambiri ya masensa owongolera injini, kuphatikiza sensa ya kutentha, sensa yothamanga, sensa yothamanga ndi ngodya, sensa yotuluka, sensa yamalo, sensa yotsekereza gasi, sensor yogogoda ndi zina zotero. Sensa yamtunduwu ndiye pakatikati pa injini yonse. Kugwiritsa ntchito kungathe kupititsa patsogolo mphamvu ya injini, kuchepetsa kugwiritsa ntchito mafuta, kuchepetsa mpweya wotulutsa mpweya, kuwonetsetsa zolakwika, etc. za masensa wamba. Pali zofunikira zambiri pazizindikiro zawo zogwirira ntchito, zomwe chofunikira kwambiri ndikulondola kwa kuyeza ndi kudalirika, apo ayi cholakwika chomwe chimayambitsidwa ndi kuzindikira kwa sensor pamapeto pake chidzatsogolera kulephera kwa dongosolo la injini kapena kulephera.

1. Sensa ya kutentha:

makamaka amazindikira kutentha kwa injini, kutentha kwa gasi, kutentha kwa madzi ozizira, kutentha kwamafuta amafuta, kutentha kwamafuta a injini, kutentha kothandizira, ndi zina zambiri. Thermistor ndi thermocouple zimatengera kutentha kwamphamvu. Waya chilonda kukana kutentha sensa ali olondola mkulu, koma makhalidwe osauka poyankha; Sensa ya Thermistor ili ndi chidwi chachikulu komanso mawonekedwe abwino oyankhira, koma mizere yoyipa komanso kutentha kocheperako. Mtundu wa Thermocouple uli ndi kulondola kwambiri komanso kusiyanasiyana koyezera kutentha, koma amplifier ndi kuzizira komaliza kumayenera kuganiziridwa.

2. Pressure sensor:

makamaka amazindikira kukakamizidwa mtheradi wa kudya zobwezedwa, zingalowe digiri, mumlengalenga kuthamanga, injini mafuta kuthamanga, ananyema mafuta kuthamanga, tayala kuthamanga, etc. ) ndi pamwamba elastic wave (SAW) amagwiritsidwa ntchito kwambiri. Sensor capacitive imakhala ndi mphamvu zowonjezera, kuyankha kwamphamvu komanso kusinthasintha kwachilengedwe. Varistor imakhudzidwa kwambiri ndi kutentha, choncho imayenera kukhazikitsa dera lolipirira kutentha, koma ndiloyenera kupanga zambiri. Mtundu wa LVDT uli ndi kutulutsa kwakukulu, komwe kumakhala kosavuta kutulutsa digito, koma kukana kwake kugwedezeka ndikosavuta; SAW ndi sensa yabwino chifukwa cha kukula kwake kochepa, kulemera kwake, kutsika kwa mphamvu, kudalirika kwakukulu, kukhudzidwa kwakukulu, kusamvana kwakukulu ndi kutulutsa digito.
