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，遼寧lcr電橋價格，應(yīng)設(shè)計一個壓電陶瓷夾具（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，遼寧lcr電橋價格，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)，遼寧lcr電橋價格，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。選擇LCR數(shù)字電橋關(guān)心的主要方面：測量準(zhǔn)確度，測試信號頻率與電平，儀器價位。遼寧lcr電橋價格</p><div

style="text-indent:25px">在我們的生活中電氣行業(yè)到處可見，隨著經(jīng)濟(jì)的發(fā)展，電氣行業(yè)的發(fā)展越來越快，電子產(chǎn)品部件也成為比較重要的部件之一。其中數(shù)字橋已成為工業(yè)生產(chǎn)活動不可或缺的設(shè)備。但是，很多人不知道數(shù)字橋的原理是什么，那么就來簡單介紹一下數(shù)字橋的原理吧。數(shù)字橋的測量對象是阻抗元件的參數(shù)，包括交流電阻r、電感l(wèi)及其質(zhì)量系數(shù)q、電容c及其損耗系數(shù)d。其測量用頻率從商用頻率到約100千赫。基本測量誤差為0.02%，一般為0.1%左右。數(shù)字橋的原理可以表示為Zx=Ux/Ix=Rr * Ux/Ur。這個公式是相位量關(guān)系公式。從這個結(jié)構(gòu)來看，數(shù)字橋只是繼承了橋的傳統(tǒng)稱呼。新興傳感器技術(shù)作為傳感網(wǎng)的基礎(chǔ)元件,在今后將有十分廣闊的發(fā)展前景其中就包含LCR數(shù)字電橋.</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">直流偏置源和市場上的直流電源一樣嗎？(1)直流偏流源是一個恒流源，輸出時呈現(xiàn)的分布電容電感應(yīng)該很小，其大小決定偏流源與LCR測試的帶寬，而普通市場上的直流電源沒有這些指標(biāo)。(2)若要將市售的直流電源做成偏流源要加很大的電感器，來提高電源本身交流輸出阻抗，該方法在電橋頻率大于10KHZ時基本不能實現(xiàn)。直流偏置電流源可以疊加到幾安培？直流偏置電流源TH1772B可以疊加到30安培,TH1773和TH1775不能疊加,TH1776可以疊加到40安培。直流偏置電流源在有些頻率下為何無法清零?交流輸出阻抗頻響不一致，在某些頻率點可能產(chǎn)生諧振。LCR數(shù)字電橋的測量速度比較的快,測量出來的精確度比較的高。肇慶lcr數(shù)字電橋推薦</p><p style="text-indent:25px">傳統(tǒng)LCR電橋的信號源阻抗隨著量程的變化而變化的。遼寧lcr電橋價格</p><p style="text-indent:25px">為什么同一個電感在不同廠家的LCR儀器上用相同測試條件,電感測試數(shù)據(jù)會有很大差別？因為絕大多數(shù)電感都帶有鐵芯磁芯，而帶有鐵芯磁芯的電感對其施加的磁場非常敏感，磁場與測試信號電流成正比，因此相同電平若內(nèi)阻不同，電流就會不一樣，則結(jié)果有很大差別。這是客戶電感測試時遇到的普遍問題。再有就是判定儀器測試電感的一致性原則應(yīng)該是施加與被測件上的電流要一致，這其中有一個特例，就是空心電感與磁場不敏感的。如果還有什么好的補(bǔ)充回答歡迎大家來補(bǔ)充。遼寧lcr電橋價格</p><p
