Excavator pressure sensor ndiye sensor yomwe imagwiritsidwa ntchito kwambiri, ndi mawu wamba pozindikira mpweya, madzi, olimba ndi zinthu zina pakati pa inductive mphamvu mphamvu, imaphatikizansopo.
Manometers omwe amayeza kuthamanga kwa mpweya pamwamba ndi zoyezera za vacuum zomwe zimayeza kuthamanga kwa mpweya pansi pake. Pali mitundu yambiri ya sensa yamphamvu, njira yoyezera yachikhalidwe ndiyo kugwiritsa ntchito mapindikidwe ndi kusuntha kwa zinthu zotanuka kuti afotokoze kukonza kwa injini ya jakisoni yamagetsi, koma kuchuluka kwake ndikwambiri, kovutirapo, ndipo zotulutsa zake sizofanana. Ndi kukula kwa luso la microelectronics, kugwiritsa ntchito zida za semiconductor piezoresistive effect ndi kusungunuka kwapamwamba, kukula kwa masensa a semiconductor mphamvu, piezoresistive yofunika ya silicon piezoresistive ndi capacitive awiri, ali ndi kukula kochepa, kulemera kwake, ubwino wambiri wokhudzidwa, amagwiritsidwa ntchito kwambiri mu mphamvu ya semiconductor. masensa. Pamene semiconductor imatsindika pamwamba pa kristalo, resistivity yake idzasintha. Ubale pakati pa kusintha kwa conductor resistivity ndi kupsyinjika kumatchedwa semiconductor piezoresistive effect, ndipo makina opangira magetsi opangidwa ndi izi amatchedwa piezoresistive force sensor, yomwe ili ndi mitundu iwiri, imodzi ndi sensor yopangidwa ndi semiconductor strain gauge elastic element, yomwe imatchedwa pasted piezoresistive sensor. Chinanso ndi kukana kwapang'onopang'ono kopangidwa ndi ukadaulo wophatikizika wozungulira pagawo laling'ono la semiconductor, kotero kuti geji ya strain ndi silicon gawo lapansi zimapanga sensa yonse yofanana, yotchedwa diffusion piezoresistive sensor. Lili ndi makhalidwe okhudzidwa kwambiri, kulondola kwakukulu, kukula kochepa, kulemera kochepa, maulendo apamwamba ogwira ntchito, kapangidwe kosavuta, ntchito yodalirika komanso moyo wautali.
