Kuyerekeza kwaStrain Gauge Load Cellndi Digital Capacitive Sensor Technology

Ma cell a capacitive ndi strain gauge load amadalira zinthu zotanuka zomwe zimapunduka poyankha katundu woyezedwa.

Zomwe zimapangidwa ndi zinthu zotanuka nthawi zambiri zimakhala aluminiyumu yama cell katundu otsika mtengo komanso chitsulo chosapanga dzimbiri pama cell onyamula pamafakitale owononga mafakitale.

Ma capacitive strain gauge sensors amayesa kusinthika kwa zinthu zotanuka payekhapayekha, ndipo kutulutsa kwa masensa kumasinthidwa ndi dera lamagetsi kukhala chizindikiro choyimira katundu.

Sensor capacitive ndi conductor yomwe imayikidwa patali pang'ono kuchokera kuzinthu zotanuka ndikuyesa kupunduka popanda kukhudzana ndi zinthu zotanuka, pomwe cholumikizira cholumikizira ndi chotchinga chotchinga chotchinga chomangika molunjika ku chinthu chotanuka kuti chiwonekere mwachindunji pakugwedezeka ndi kulemetsa. , omwe nthawi zambiri amakumana nawo m'mafakitale.

Kumverera
Kuonjezera apo, ma capacitive sensors ndi ovuta kwambiri, ndi 10% kusintha kwa capacitance, pamene zojambula zojambulazo zimakhala ndi kusintha kwa 0.1% kokha.Popeza ma capacitive sensors amakhala omvera kwambiri motero amafunikira kusinthika kwapang'onopang'ono kwa zinthu zotanuka, kupsyinjika kwa cell ya capacitive load kumakhala kutsika nthawi 5 mpaka 10 kuposa cell ya strain gauge load.

Wiring ndi Kusindikiza
Kusintha kwakukulu kwa capacitance kumathandizira kupereka chizindikiro cha digito, chomwe mu cell capacitive load ndi chizindikiro chothamanga kwambiri chomwe chimasonyeza mwachindunji katundu mu g, kg, kapena Newtons.Chingwe chotsika mtengo cha coaxial chokhala ndi cholumikizira chokhala ndi waya umodzi chimalimbitsa cell yonyamula ndikutumiza chizindikiro cha digito chothamanga kwambiri kubwerera ku chida, chomwe chingakhale pamtunda wa mita.Mu cell yolemetsa yamtundu wa analogi, mphamvu yamagetsi ndi siginecha yotsika ya analogi nthawi zambiri imayendetsedwa ku chipangizocho kudzera pa waya wokwera mtengo kwambiri wa 6 pomwe chizindikiro cha analogi chimasinthidwa kukhala digito.Mu cell strain gauge load cell, chokulitsa ndi kutembenuka kwa A/D chimayikidwa mnyumbamo, ndipo mphamvu ndi ma siginecha a digito nthawi zambiri amayendetsedwa ndi zida kudzera pa zingwe zamawaya 6 kapena 7 zodula.
