Papiso eaStrain Gauge Load Cellle Digital Capacitive Sensor Technology
Ka bobeli lisele tsa capacitive le strain gauge load li itšetlehile ka likarolo tse rekere tse holofetseng ho arabela mojaro o lokelang ho lekanyetsoa.
Thepa ea elastic element hangata ke aluminium bakeng sa lisele tsa thepa e theko e tlase le tšepe e sa hloekang bakeng sa lisele tsa meroalo lits'ebetsong tse senyang tsa indasteri.
Li-sensor tsa capacitive strain gauge li lekanya ho senyeha ha likarolo tsa elastic ka bonngoe, 'me tlhahiso ea li-sensor e fetoloa ke potoloho ea elektroniki hore e be lets'oao le emelang mojaro.
Sensor capacitive ke conductor e behiloeng sebakeng se senyenyane ho tloha ho elastic element 'me e lekanya deformation ntle le ho kopana le ntho ea elastic, athe gage ea khatello ke foil e thibelang ho itšireletsa e kopantsoeng ka ho toba le ntho ea elastic e le hore e pepesehe ka ho toba ka ho makala le ho feta. , tseo hangata li kopanang le tsona lits'ebetsong tsa indasteri.
Kutloisiso
Ho feta moo, li-capacitive sensors li na le kutloelo-bohloko haholo, ka phetoho ea 10% ea bokhoni, ha li-gauge tsa mofuta oa foil li na le phetoho ea 0.1% feela ea ho hanyetsa. Kaha li-sensor tsa capacitive li na le kutloelo-bohloko haholo 'me ka hona li hloka deformation e tlase haholo ea element elastic, khatello ea karolo ea elastic ea sele ea capacitive e tlase ka makhetlo a 5 ho isa ho a 10 ho feta ea sele ea boima ba khatello.
Wiring le ho Tiisa
Phetoho e phahameng ea bokhoni e thusa ho fana ka pontšo ea tlhahiso ea digital, eo liseleng tsa capacitive load e leng letšoao la lebelo le phahameng le hlalosang mojaro ka ho toba ka g, kg, kapa Newtons. Mohala oa coaxial oa theko e tlase o nang le sehokedi se tiisitsweng sa terata e le nngwe o matlafatsa sele ya mojaro mme o fetisetse letshwao la dijithale la lebelo le phahameng ho sesebediswa, se ka bang bohole ba dimithara tse makgolo. Ka selefounong e tloaelehileng ea analog strain gauge load, phepelo ea motlakase le lets'oao la analoge ea boemo bo tlase hangata li tsamaisoa ho sesebelisoa ka thapo e theko e phahameng haholo ea terata ea 6 moo lets'oao la analoge le fetoleloang ho dijithale. Ka seleng ea boima ba digital strain gauge, amplifier le A/D converter li beoa ka tlung, 'me matla le mats'oao a dijithale hangata a tsamaisoa ho sesebelisoa ka likhoele tsa terata tse 6 kapa tse 7 tse turang haholo.
