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%，成都lcr電橋維修，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，成都lcr電橋維修。這個公式是相位量關(guān)系公式。從這個結(jié)構(gòu)來看，成都lcr電橋維修，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.成都lcr電橋維修</p><div

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。成都lcr電橋維修LCR數(shù)字電橋在工廠、院校、研究所、計量質(zhì)檢部門等場所已經(jīng)開始發(fā)揮獨特的優(yōu)勢。</p><div

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。</p><p style="text-indent:25px">試舉一例來加以說明即使在產(chǎn)品樣本上給定基本準(zhǔn)確度相同，實際是有很大區(qū)別的，我們以TH2818、TH2828 兩款產(chǎn)品加以說明。TH2818：頻率20Hz—300KHz，基本準(zhǔn)確度0.05%。TH2828：頻率20Hz—1MHz，基本準(zhǔn)確度0.05%假定儀器測試條件均為慢速、電平1Vrms、溫度20oC，對100pF、10nF 電容器進行測試，評估其在不同頻率下的測量準(zhǔn)確度，比如說容量均為100pF，型號2818頻率100Hz的測試值為4.06，型號2828頻率100Hz的測試值為0.3。所以實驗表明即便是相同基本準(zhǔn)確度的儀器，在不同量值被測件和不同頻率下其準(zhǔn)確度是有很大區(qū)別的。在操作LCR數(shù)字電橋時，應(yīng)在技術(shù)指標(biāo)規(guī)定的環(huán)境中工作。</p><div

style="text-indent:25px">為了減少測量誤差，LCR測試儀具有若干校正功能。校正值根據(jù)頻率和阻抗的量程不同會有所不同，所以進行全范圍的校正要花費很多時間。這里對零點校正和負(fù)荷校正進行解說。零點校正:當(dāng)LCR測試儀的零點漂移對于測量值不能忽略時，就需要進行零點校正。因為零點漂移會隨著電纜和電極的物理配置不同而變化，所以進行開路和閉路的零點校正時，必須與連接零部件時的電纜布線、電極間隔等相同。負(fù)荷校正:除了測量夾具等不同所引起的零點漂移以外，如果還有不能夠忽略的測量誤差，那么可以進行負(fù)荷校正，以提高測量精確度。即使對于沒有負(fù)荷校正功能的LCR測試儀，也能夠?qū)Ω鱾€阻抗量程和頻率求取校正系數(shù)，自己進行校正。成都lcr電橋維修</p><p
