ʻIke kūlana kūlana capacitive

1.Capacitive position sensor mea he non-contact position sensor, ka mea maʻamau i loko o ekolu mahele: 'ike wahi, pale pale a me ka pūpū. Hiki iā lākou ke ana i ke kūlana pololei o ka pahuhopu, akā ʻo ka mea wale nō. Inā ʻaʻole conductive ka mea i ana ʻia, pono ia e ana i kona mānoanoa a i ʻole kona mānoanoa.

2.I ka ana ana i ka conductive mea, ka hoailona hoʻopuka 'aʻohe mea e pili ana i ka mea o ka mea, no ka mea, no ka capacitive displacement sensor, nā conductors a pau i ka electrode like. Hoʻohana nui ʻia kēia ʻano sensor i ka disk drive, ka ʻenehana semiconductor a me ke ana ʻoihana kiʻekiʻe kiʻekiʻe, akā pono ia i ka pololei kiʻekiʻe a me ka pane pinepine. Ke hoʻohana ʻia e ana i nā mea hoʻokele ʻole, hoʻohana mau ʻia nā mea ʻike kūlana capacitive e ʻike i nā lepili, nā uhi a me ke ana ʻana i ka mānoanoa o ka pepa a i ʻole ke kiʻiʻoniʻoni.

3. Hoʻohana mua ʻia ka mea ʻike kūlana Capacitive e ana i ka mamao o ka neʻe ʻana o ka laina, mai kekahi mau millimeters a i kekahi mau nanometer, a ua hoʻopau ʻia ke ana ma ka hoʻohana ʻana i nā ʻano uila o ka conductivity. Ua kapa ʻia ka hiki o kahi mea ke mālama i ka uku. ʻO kahi mea capacitor maʻamau no ka mālama ʻana i ka uku he pā capacitor. ʻO ka capacitance o ka pā capacitor e pili pono ana i ka wahi electrode a me ka dielectric mau, a me ka inversely proportional i ka mamao ma waena o nā electrodes. No laila, ke loli ka mamao ma waena o nā electrodes, hoʻololi pū ka capacitance. Ma kahi huaʻōlelo, hoʻohana ka sensor kūlana capacitive i kēia ʻano e hoʻopau i ka ʻike kūlana.

4.A typical capacitive position sensor komo elua metala electrodes, me ka ea e like me ka dielectric. ʻO kekahi electrode o ka sensor he pā metala, a ʻo ka electrode ʻē aʻe o ka capacitor i haku ʻia me kahi mea conductive e ʻike ʻia. Ke hoʻohana ʻia ka volta ma waena o nā papa conductor, ua hoʻokumu ʻia kahi māla uila ma waena o nā papa, a mālama nā papa ʻelua i nā koina maikaʻi a me nā koina maikaʻi ʻole. Hoʻohana maʻamau ka sensor position capacitive i ka volta AC, ka mea e hoʻololi pinepine ai i ka polarity o ka pā ma ka pā, no laila hiki ke ʻike ʻia ka hoʻololi ʻana o ke kūlana ma ke ana ʻana i ka capacitance ma waena o nā papa ʻelua.

5. Hoʻoholoʻia ka capacitance e ka mamao ma waena o nā papa, ka dielectric mau o ka dielectric a me ka mamao ma waena o nā papa. I ka hapa nui o nā mea ʻike, ʻaʻole e loli ka ʻāpana a me ka dielectric mau o ka pā electrode, ʻo ka mamao wale nō e hoʻopili i ka capacitance ma waena o ka electrode a me ka mea i manaʻo ʻia. No laila, hiki i ka hoʻololi o ka capacitance ke hōʻike i ke kūlana pahuhopu. Ma o ka calibration, ua loaʻa i ka hōʻailona voltage puka o ka sensor kahi pilina laina me ka mamao ma waena o ka papa ʻike a me ka pahuhopu. ʻO kēia ka sensitivity o ka sensor. Hōʻike ia i ka ratio o ka hoʻololi ʻana o ka volta puka i ka hoʻololi kūlana. ʻO ka mea maʻamau ka 1V/ micron, ʻo ia hoʻi, hoʻololi ka volta puka i 1V i kēlā me kēia 100 microns.

6. Ke hoʻohana ʻia ka volta i ka wahi ʻike, e hoʻokumu ʻia kahi māla uila i hoʻopuehu ʻia ma ka mea i ʻike ʻia. I mea e hōʻemi ai i ka hoʻopilikia, hoʻohui ʻia kahi papa pale. Hoʻohana ia i ka ikaika electromotive like ma nā ʻaoʻao ʻelua o ka wahi ʻike e pale ai i ke kahua uila i ka lumi ʻike mai ka hū ʻana. ʻO nā mea hoʻokele ma waho o nā wahi ʻike ʻē aʻe e hoʻokumu i kahi kahua uila me ka papa pale a ʻaʻole e hoʻopilikia i ke kahua uila ma waena o ka pahuhopu a me ka wahi ʻike. Ma muli o ka pale pale, he conical ke kahua uila ma ka wahi ʻike. ʻO ka wahi i manaʻo ʻia o ke kahua uila i hoʻokuʻu ʻia e ka electrode detection he 30% ka nui ma mua o ka wahi ʻike. No laila, ʻo ka ʻāpana anawaena o ka mea i ʻike ʻia he 30% ka nui ma mua o ka ʻāpana ʻike o ka mea ʻike.
