Nhanganyaya
A capacitive pressure sensor imhando ye sensor inoyera kudzvanywa kuburikidza nekuchinja mune capacitance. Inoshanda nekuyera shanduko ye capacitance pakati pema electrode maviri e capacitor kuti ione kudzvanywa kwakasiyana. Aya masensa anoshandiswa zvakanyanya mumaindasitiri otomatiki, michina yekurapa, mota, uye maindasitiri emuchadenga nekuda kwekunyanya kurongeka, kunzwa, uye kuvimbika.
Kushanda Nheyo yeCapacitive Pressure Sensors
Basic Principle yeCapacitance Shanduko
A capacitor ine ma electrode maviri uye dielectric zvinhu. Kana chinhambwe chiri pakati pema electrode kana zvimiro zve dielectric zvinhu zvinoshanduka, iyo capacitance kukosha inoshanduka zvakare. Mune capacitive pressure sensors, shanduko iyi inoratidzira zvakananga kusiyanisa kwekumanikidza.
Hukama pakati peCapacitance uye Pressure
Mune capacitive pressure sensor, shanduko mukudzvinyirirwa inokonzera mutsauko uri kure pakati pema electrode kana deformation ye dielectric material, zvichikonzera shanduko ye capacitance. Iyi shanduko ye capacitance inoshandurwa kuita chiratidzo chemagetsi kuburikidza nemaseketi emagetsi, zvichibvumira kuyerwa kwekumanikidza. Hukuru hwechiratidzo chemagetsi chakaenzana nedzvinyiriro yakashandiswa, ichigonesa kuratidzwa kwakaringana kwekumanikidza shanduko.
