Excavator pressure sensor o le faʻaoga sili ona faʻaaogaina, o se faaupuga lautele mo le suʻeina o kesi, vai, malosi ma isi mea i le va o le malosi malosi, e aofia ai foi.
Manometers e fua ai le mamafa o le ea i luga ma fua vacuum e fua ai le mamafa o le ea i lalo. E tele ituaiga o faʻamalosi malosi, o le fua faʻaleaganuʻu masani o le faʻaaogaina lea o le deformation ma le faʻaogaina o elemene elastic e faʻaalia ai le tausiga o le afi eletise eletise, ae o lona voluma e tele, faʻafefe, ma o le gaosiga e le laina. Faatasi ai ma le tuputupu aʻe o tomai microelectronics, o le faʻaaogaina o mea semiconductor piezoresistive aafiaga ma elasticity sili atu, o le atinaʻeina o masini semiconductor malosi, silicon piezoresistive ma capacitive lua, latou te laʻititi laʻititi, mama mama, maualuga lagona lelei, e faʻaaogaina lautele i le malosi semiconductor. fa'alogo. Pe a faʻamalosia se semiconductor i luga o se tioata, o le a suia lona resistivity. O le sootaga i le va o le suiga o le conductor resistivity ma le atuatuvale ua taʻua o le semiconductor aafiaga piezoresistive, ma o le masini tele masini e faia i lenei aafiaga ua taʻua o le piezoresistive malosi sensor, lea e lua ituaiga, o le tasi o le leo faia i le semiconductor strain gauge faapipii i luga o le. elemene elastic, lea e taʻua o le pasted piezoresistive sensor. O le isi o le diffusion resistance e faia i tekinolosi faʻatekonolosi fesoʻotaʻi i luga o le substrate o mea semiconductor, ina ia faʻapipiʻi le fua faʻatatau ma le silicon substrate tutusa atoa sensor, e taʻua o le diffusion piezoresistive sensor. O loʻo i ai uiga o le maualuga o le lagona, maualuga le saʻo, laʻititi laʻititi, mamafa mama, maualuga le galue, fausaga faigofie, galuega faʻalagolago ma le ola umi.
