Flat Capacitive Sensor yog ib qho uas tsis yog -sib cuag sensor uas siv lub tiaj tus qauv tsim thiab ntes cov khoom raws li lub hauv paus ntsiab lus ntawm kev hloov capacitance. Nws cov duab tiaj tus (feem ntau yog nyias, nrog lub duab plaub lossis square detection nto) tso cai rau nws los nruab rau hauv qhov chaw - txwv qhov chaw, xws li cov khoom siv, cov khoom siv conveyor sab, thiab lwm yam. Cov qauv no tsis tsuas yog txuag qhov chaw teeb tsa tab sis kuj tso cai rau qhov chaw nrhiav kom pom ze dua rau lub hom phiaj khoom, txhim kho kev ruaj ntseg.
Los ntawm txoj cai nrhiav kom pom, muaj ib lub phaj capacitor hauv lub sensor. Thaum ib yam khoom (txawm yog hlau lossis tsis yog{1}}hlau) mus txog qhov chaw kuaj pom, lub capacitor yog tsim los ntawm cov khoom thiab phaj, ua rau tus nqi capacitance ntawm lub sensor hloov. Lub sensor txiav txim siab seb ib yam khoom puas muaj los ntawm kev kuaj xyuas qhov kev hloov pauv no, thiab tom qab ntawd tso tawm cov teeb liab sib cuam tshuam.
Nyob rau hauv cov nqe lus ntawm cov zis hom, Flat Capacitive Sensors kuj tau muab faib ua NPN thiab PNP, uas tau yoog rau ntau hom kev tswj hwm cov tswv yim. Nws qhov kev kuaj pom qhov deb feem ntau yog kho tau, thiab cov neeg siv tuaj yeem teeb tsa qhov kev tshawb pom tsim nyog los ntawm lub pob qhov rooj lossis hloov ntawm lub sensor raws li qhov xav tau tiag tiag kom tsis txhob muaj qhov yuam kev.

Vim nws qhov tsis tshua muaj dielectric poob, nws tuaj yeem siv tau ntawm ntau zaus, ua rau muaj kev ua haujlwm siab ntawm qhov system. Nws tuaj yeem siv los ntsuas cov ntsuas uas sib txawv sai.
4. Nws tuaj yeem ntsuas tsis yog -kev tiv tauj thiab muaj qhov rhiab heev
Tsis yog -kev ntsuas kev vibration los yog eccentricity ntawm rotating ncej, radial clearance ntawm me me pob bearings, thiab lwm yam. Thaum tsis yog - kev ntsuas yog siv, tiaj tus capacitive sensors muaj ib tug nruab nrab nyhuv, uas yuav txo tau lub zog ntawm workpiece nto roughness thiab lwm yam nyob rau hauv qhov ntsuas.
FAQ
Q: Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm lub tiaj tus capacitive sib thooj sensors piv rau cov qauv cylindrical sensors?
Lub ntsiab kom zoo dua ntawm lub tiaj tus capacitive sib thooj sensors nyob rau hauv lawv cov ultra-thin design, ua rau lawv zoo tagnrho rau cov ntawv thov uas txwv qhov chaw installation. Vim lawv qhov loj thiab tsis sib xws, lawv muaj kev nkag siab thiab ruaj khov thaum kuaj pom cov khoom loj (xws li pawg ntawm cov ntawv, cov laug cam, lossis cov thawv kua). Tsis tas li ntawd, cov qauv tiaj tus feem ntau muaj qhov dav dav thiab tsis tshua muaj kev cuam tshuam rau cov neeg kho tshuab kev co, ua rau nws tsim nyog rau qhov chaw mounting lossis embedded installation.
Q: Thaum xaiv ib lub sensor, kuv yuav txiav txim siab seb kuv xav tau lub capacitive lossis inductive sib thooj sensor?
Qhov no yog cov lus nug tseem ceeb tshaj plaws xaiv. Qhov sib txawv tseem ceeb nyob hauv qhov khoom raug kuaj pom:
Capacitive sensors: tuaj yeem ntes yuav luag txhua yam khoom (hlau, tsis yog{0}}hlau, kua, hmoov, thiab tib neeg lub cev). Yog tias koj yuav tsum kuaj xyuas lub raj mis yas, iav phaj, thawv ntawv, ntoo, qib kua, lossis cov ntaub ntawv granular, koj yuav tsum xaiv lub ntsuas ntsuas capacitive.
Inductive sensors: Tsuas tuaj yeem ntes cov khoom hlau. Rau kev tshawb nrhiav hlau, lawv feem ntau yog qhov tseeb thiab ruaj khov, thiab tsis muaj kev cuam tshuam zoo los ntawm cov khoom tsis yog -hlau cuam tshuam (xws li dej thiab hmoov av).
Txoj cai yooj yim: tsuas yog kuaj pom hlau → xaiv inductive; nrhiav tsis tau -hlau los yog ntau yam ntaub ntawv → xaiv capacitive. Pav ca capacitive sensors, vim lawv qhov loj ntawm qhov chaw pom, tshwj xeeb tshaj yog tsim rau kev kuaj xyuas cov khoom loj uas tsis yog-hlau lossis rau kev tshawb pom los ntawm cov thawv ntsa.
Q: Cov pav ca capacitive sensors puas tuaj yeem siv rau kev ntsuas cov kua hauv cov ntim hauv cov khoom noj lossis tshuaj lom neeg kev lag luam? Cov kev cai tshwj xeeb yog dab tsi?
Yog lawm, qhov no yog ib qho ntawm nws qhov zoo tshaj plaws daim ntawv thov scenarios. Nws tuaj yeem kuaj pom qhov muaj / theem ntawm cov kua lossis cov khoom siv hauv cov khoom tsis yog-cov thawv hlau (xws li yas lossis iav jars) los ntawm lub thawv phab ntsa.
Cov cai tshwj xeeb:
Cov khoom siv sib xws: Cov khoom siv ntawm qhov ntsuas qhov ntsuas qhov chaw (feem ntau yog PBT lossis stainless hlau) yuav tsum tiv taus cov tshuaj ntxuav, cov kua dej corrosive, lossis cov zaub mov txaws hauv thaj teb. Nws qhov kev tiv thaiv ntsuas (IP ntsuas) yuav tsum tau lees paub.
Thawv phab ntsa thickness: Lub thawv phab ntsa thickness yuav tsum nyob rau hauv lub sensor "kev muaj peev xwm nkag mus." Cov qauv sib txawv muaj peev xwm sib txawv; thov saib cov specifications. Cov phab ntsa tuab heev yuav ua rau tsis muaj peev xwm txheeb xyuas lossis tsis tshua muaj siab.
Kev txhim kho thiab kho: Lub sensor yuav tsum nruj thiab sib npaug rau sab nrauv ntawm lub thawv, tsis muaj qhov sib txawv ntawm huab cua. Corrosion-tiv thaiv mounting brackets los yog nplaum feem ntau yuav tsum tau kho, thiab sab nrauv ntawm lub thawv phab ntsa yuav tsum huv si thiab tiaj tus.
