Mphamvu ya sensa ndi imodzi mwama sensor anayi omwe amathandizira makina opangira mafakitale.Mphamvu-sensitive element imatanthawuza chinthu chomwe chimatha kumva (kapena kuyankha) kukakamiza mu sensa yamphamvu.Mphamvu imaphatikizapo kuchuluka kwa thupi monga mphamvu yokoka, kukanikiza, kuthamanga, mphindi ndi mphamvu zopondereza.

1.zofunikira

Zinthu zogwira mphamvu ndi masensa zimagwiritsidwa ntchito kwambiri m'madipatimenti osiyanasiyana opanga mafakitale komanso kuyesa kwasayansi.Pali mitundu yambiri ndi mafotokozedwe a zinthu zomwe zimakhudzidwa ndi mphamvu ndi masensa, omwe amatha kugawidwa m'njira zosiyanasiyana.Njira yachikhalidwe yoyezera mphamvu imawonetsedwa ndi kusinthika ndi kusamuka kwa zinthu zotanuka, zomwe zimadziwika ndi mtengo wotsika komanso osafunikira magetsi, koma zimakhala zazikulu komanso zazikulu, ndipo zotulutsa zake sizikhala zamagetsi.Pambuyo pake, zida zoyezera zovuta zidapezeka, makamaka ndi chitukuko chaukadaulo wa ma microelectronics, masensa a semiconductor mphamvu ndi mphamvu zamagetsi zidapangidwa pogwiritsa ntchito mphamvu ya piezoresistive komanso elasticity ya zida za semiconductor komanso ukadaulo wophatikizika wozungulira, womwe udapita patsogolo kwambiri pamtundu woterewu.Masensa omwe amagwiritsidwa ntchito nthawi zambiri ndi resistive, piezoelectric, capacitive, variable kukana, kuwala kwa fiber ndi zina zotero.M'zaka zaposachedwa, ma sensor amtundu wamtundu wamagetsi, magnetostrictive pressure sensor, mphamvu yamagetsi ndi masensa ena amagetsi apangidwa.

Mphamvu yamagetsi yosinthika imayesa ma voliyumu olowera ndi ma siginecha apano posinthana pakali pano, kenako ndikulumikiza zomwe zasankhidwa ndi chida chachiwiri cha digito kudzera pamakina opatsirana monga zingwe ndi ulusi wapamaso.Chida chachiwiri cha digito chimawerengera kuchuluka kwa ma voteji ndi apano, ndipo chimatha kupeza magawo monga voteji yogwira ntchito, mtengo wamakono, voteji yofunika kwambiri, voteji ya harmonic, mphamvu yapano, mphamvu yogwira, mphamvu yofunikira ndi mphamvu ya harmonic.

2.kusinthasintha pafupipafupi mphamvu kachipangizo ndi oyenera mphamvu pafupipafupi magetsi kuchuluka muyeso ndi metering.

3. sensa yamagetsi yamagetsi ndi yoyenera kuyeza ndi kuyeza kwa magawo aliwonse amagetsi mkati mwa bandwidth.

Amagwiritsidwa ntchito kwambiri poyendetsa magetsi, ma motors, mafani, mapampu, kupanga mphamvu yamphepo, mayendedwe anjanji, magalimoto amagetsi, otembenuza pafupipafupi, osinthira apadera, nyali za fulorosenti, kuyatsa kwa LED ndi magawo ena owunika ndi kuyesa kwazinthu, kuwunika kwamphamvu kwamagetsi ndi kusanthula kwamphamvu kwamphamvu.
