style="text-indent:25px">在振動式料位開關(guān)研發(fā)中，一般通過LCR數(shù)字電橋來準(zhǔn)確測量壓電陶瓷的電容值。通常壓電陶瓷的電容值會受擠壓影響而變化，為減少測量誤差，應(yīng)設(shè)計(jì)一個壓電陶瓷夾具（如上圖所示），然后用電橋電纜兩個夾子夾住自制夾具的兩個電極，將壓電陶瓷放入夾具的兩個銅片中來測量。壓電陶瓷的靜態(tài)電容測量中，測量結(jié)果還與測量環(huán)境密切相關(guān)，特別是環(huán)境濕度和空氣流動，這導(dǎo)致儀表顯示結(jié)果往往極不穩(wěn)定，電橋顯示的電容值處于變化跳動狀態(tài)，隨后數(shù)值跳動頻率變小，直到數(shù)值變化很緩，且數(shù)值時大時小變化。</p><p style="text-indent:25px">作為一個新用戶，怎樣選擇一款lcr數(shù)字電橋？首先是看儀器的測試準(zhǔn)確度，看儀器的測試頻率，看儀器的測試電平。儀器的輸出阻抗或稱內(nèi)阻。其他視客戶使用具體情況而定，或者可以根據(jù)客戶的實(shí)際情況向同深圳市展榮新精密電子有限公司技術(shù)咨詢。對于一個已知的“電容”，客戶該選用什么樣的測試條件?1.小于100pF電容用1MHZ頻率測量，中等容量如(1000pF-10uF)用1KHZ,10KHZ,100KHZ，國家標(biāo)準(zhǔn)測試中等電容的測試頻率標(biāo)準(zhǔn)是1KHZ。電解類如鋁電解，鉭電解等用100HZ或120HZ。2.從電平的角度說大部分電容對電平不敏感，不同電平測試變化不大，但有些介電常數(shù)大的電容與電平非常敏感，應(yīng)仔細(xì)選擇電平。目前大多的工廠、各種實(shí)驗(yàn)室都會大量的使用到電橋，電橋的品種、型號繁多。</p><div

style="text-indent:25px">由于不同儀器的測試信號電流的不同、則使用不同測試儀器時可能會得到不同的測試結(jié)果，這主要取決于儀器的信號源輸出電壓和信號源內(nèi)阻。在連接時，連接合適的測試夾具或測試電纜（儀器隨機(jī)配有四端開爾文測試電纜、頂針測試夾具、測試鉗）。選擇擇所需的測量頻率信號電平。不要在較大輸出電流的情況下（10A以上）隨意松動測試夾，以防造成意外打火或損壞。同時該設(shè)備采用除法器的原理測量低阻值，即R=U/I，當(dāng)儀器處于復(fù)位狀態(tài)時，因I=0，阻值顯示為不穩(wěn)定狀態(tài)是正?，F(xiàn)象。LCR數(shù)字電橋的測試電平以測試正弦波信號的有效值進(jìn)行設(shè)定。東莞自動lcr測量儀</p><p
