Tsis paub meej ncej nrug deb capacitive sensor
Qhov sib txawv ntawm qhov sib txawv capacitive sensor yog dav siv hauv kev lag luam, kev tshawb fawb tshawb fawb, thiab lub neej txhua hnub vim lawv qhov kev xav tau siab thiab muaj peev xwm los ntsuas qhov ntsuas nrawm nrawm. Lub hauv paus ntsiab lus tseem ceeb ntawm lawv daim ntawv thov yog nyob rau hauv kev hloov ntau yam ntawm lub cev (xws li lub zog, quab yuam, kev co, thiab lwm yam) rau hauv kev hloov pauv ntawm daim hlau, thiab tom qab ntawd kuaj xyuas qhov kev hloov pauv ntawm lub peev xwm.
Nov yog thaj chaw thov tseem ceeb thiab cov piv txwv tshwj xeeb
I. Kev ntsuas feeb txav thiab kev vibration
Qhov no yog daim ntawv thov ncaj qha tshaj plaws. Lub sensor ncaj qha ntsuas qhov hloov chaw, txoj hauj lwm, lossis kev vibration amplitude ntawm ib yam khoom.
Piv txwv daim ntawv thov:
- Precision Shaft Displacement Measurement: Ntsuas qhov radial runout lossis axial hloov chaw ntawm lub rotating ncej.
- Kev ntsuas kev vibration: Siv los ntsuas qhov kev vibration amplitude thiab zaus ntawm cov cuab yeej xws li cav, turbines, thiab tshuab cuab yeej. Nws qhov tsis yog -kev sib cuag tsis cuam tshuam rau kev txav ntawm cov khoom ntsuas.
- Kev Tshawb Fawb Txog Cov Khoom Siv Deformation: Ntsuas cov feeb deformation ntawm cov ntaub ntawv nyob rau hauv kev ntxhov siab hauv cov chaw kuaj.
II. Kev ntsuas siab thiab quab yuam
Kev ntsuas siab los yog quab yuam yog hloov mus rau hauv kev xaav ntawm cov khoom elastic (xws li lub diaphragm lossis Bourdon raj).
Txoj Cai Ua Haujlwm:Lub phaj txav ntawm lub sensor yog elastic diaphragm. Thaum lub siab hloov pauv, lub diaphragm deforms, hloov qhov kev ncua deb mus rau lub phaj ruaj khov, yog li tso cai rau kev ntsuas siab.
Piv txwv daim ntawv thov:
- Siab Sensors / Transmitters: Dav siv nyob rau hauv cov txheej txheem tswj, aerospace, thiab rau kev ntsuas kev noj manifold siab nyob rau hauv automotive engines.
- Differential Pressure Flow Meters: xam cov kua dej ntws los ntawm kev ntsuas qhov sib txawv ntawm qhov kev txwv.
- Weighing Systems: Hloov qhov hnyav mus rau hauv lub zog, uas yog ntsuas los ntawm lub capacitive sensor.
III. Kev ntsuas nrawm
Raws li Newton txoj cai thib ob, acceleration yog ntsuas los ntawm kev txheeb xyuas qhov kev hloov pauv los ntawm inertial quab yuam.
Txoj Cai Ua Haujlwm:Lub "tsov phaj" ntawm lub sensor yog ib qho pov thawj loj txhawb nqa los ntawm cantilever beam. Thaum lub sensor nrawm, lub zog inertial ua rau cov huab hwm coj hloov pauv, hloov lub capacitance ntawm nws thiab cov phaj ruaj khov. Acceleration yog tau los ntawm kev kuaj xyuas qhov kev hloov pauv capacitance.
Piv txwv daim ntawv thov:
- MEMS Accelerometers: Qhov no yog ib qho ntawm cov kev siv tau zoo tshaj plaws. Accelerometers hauv smartphones, game controllers, drones, thiab automotive airbag systems feem ntau siv cov qauv sib txawv raws li MEMS thev naus laus zis. Lawv yog cov me, tsawg- nqi, thiab ntseeg tau.
- Muaj Cov Khoom Siv Vibration Monitoring: Siv rau kev kwv yees txij nkawm, saib xyuas kev vibration acceleration ntawm cov khoom loj.
