Sensor yowongolera 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 yotentha: makamaka imazindikira kutentha kwa injini, kutentha kwa gasi, kutentha kwa madzi ozizira, kutentha kwa mafuta amafuta, kutentha kwamafuta a injini, kutentha kwapang'onopang'ono, ndi zina zotere. Zowunikira zogwiritsira ntchito kutentha zimakhala makamaka kukana chilonda cha waya, thermistor ndi thermocouple. 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 sensa: makamaka detects kukakamizidwa mtheradi wa kudya zobwezedwa zambiri, zingalowe digiri, kuthamanga mumlengalenga, injini mafuta kuthamanga, ananyema mafuta kuthamanga, kuthamanga tayala, etc. Pali mitundu ingapo ya magalimoto kuthamanga masensa, pakati capacitive, piezoresistive, variable inductance. zoyendetsedwa ndi diaphragm (LVDT) ndi surface 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 zotulutsa zazikulu, zomwe ndizosavuta kutulutsa digito, koma kukana kwake kugwedezeka ndikotsika. SAW ndi sensa yabwino chifukwa cha kukula kwake kochepa, kulemera kwake, kutsika kwa mphamvu, kudalirika kwakukulu, kukhudzidwa kwakukulu, kusamvana kwakukulu ndi kutulutsa digito.
