<p> ICP®傳感器的信號輸出是與動態(tài)測量成比例的低阻抗電壓信號，如力、壓力或振動。該電壓信號承載在直流偏置電壓上。交流動態(tài)信號疊加在直流偏置電壓上，并允許在電源電壓和地之間擺動。與運(yùn)算放大器（Op Amp）不同，運(yùn)算放大器需要正負(fù)電源，并允許信號“騎”在地面上,并且在正負(fù)“軌”之間“擺動”，而ICP®傳感器要求輸出信號存在直流偏置。 </p> <p> 直流偏置電壓是一個很好的診斷工具。該電壓提供了一種校驗(yàn)放大器是否“接通”的方法。典型的輸入/輸出供電模塊通過一個用于信號到數(shù)據(jù)顯示設(shè)備的交流耦合的阻止電容，去除此偏置電壓。通過引出輸入到直流電壓表，偏置電壓可以得到測量。在測量供電電壓時，同時在連接傳感器后測量偏置電壓。如果偏置電壓和供電電壓相同，則系統(tǒng)開路或者沒有連接。如果偏置電壓為“0”，則系統(tǒng)可能短路了。如果偏置電壓大約會供電電壓的一半，則傳感器和電纜功能正常。

電學(xué)式傳感器—是非電量電測技術(shù)中應(yīng)用范圍較廣的一種傳感器，常用的有電阻式傳感器、電容式傳感器、電感式傳感器、磁電式傳感器及電渦流式傳感器等。 </p> <p> 電阻式傳感器是利用變阻器將被測非電量轉(zhuǎn)換為電阻信號的原理制成。電阻式傳感器一般有電位器式、觸點(diǎn)變阻式、電阻應(yīng)變片式及壓阻式傳感器等。電阻式傳感器主要用于位移、壓力、力、應(yīng)變、力矩、氣流流速、液位和液體流量等參數(shù)的測量。 </p> <p> 電容式傳感器是利用改變電容的幾何尺寸或改變介質(zhì)的性質(zhì)和含量，從而使電容量發(fā)生變化的原理制成。主要用于壓力、位移、液位、厚度、水分含量等參數(shù)的測量。 </p> <p> 電感式傳感器是利用改變磁路幾何尺寸、磁性位置來改變電感或互感的電感量或壓磁效應(yīng)原理制成的。主要用于位移、壓力、力、振動、加速度等參數(shù)的測量。 </p> <p> 磁電式傳感器是利用電磁感應(yīng)原理，把被測非電量轉(zhuǎn)換成電量制成。主要用于流量、轉(zhuǎn)速和位移等參數(shù)的測量。 </p> <p> 電渦流式傳感器是利用金屬在磁場中運(yùn)動切割磁力線，在金屬內(nèi)形成渦流的原理制成。主要用于位移及厚度等參數(shù)的測量。 </p> <p> <br /> </p><p> 電渦流傳感器要求： </p> <p> 對探頭支架的要求 </p> <p> 電渦流傳感器安裝在固定支架上，因此支架的好壞直接決定測量的效果，這就要求支架應(yīng)有足夠的剛度以提高自振頻率，避免或減小被測體振動時支架也同時受激自振，資料表明，支架的自振頻率至少應(yīng)為機(jī)械旋轉(zhuǎn)速度的10倍，支架應(yīng)與被測表面切線方向平行，傳感器垂直安裝在支架上，雖然探頭的中心線在垂直方向偏15°角時對系統(tǒng)特性沒有影響，但較好還是保證傳感器與被測面垂直。 </p> <p> 對初始間隙的要求 </p> <p> 各種型號電渦流傳感器，都在一定的間隙電壓值下，它的讀數(shù)才有較好的線性度，所以在安裝傳感器時必須調(diào)整好合適的初始間隙，對每一套產(chǎn)品都會進(jìn)行特性試驗(yàn)，繪出相應(yīng)的特性曲線，工程技術(shù)人員在使用傳感器的時候必須仔細(xì)研究配套的校驗(yàn)證書，認(rèn)真分析特性曲線，以確定傳感器是否滿足所要測量的間隙，一般傳感器直徑越大所測量間隙也越大

接近傳感器有幾種類型： </p> <p> 電容式接近傳感器 </p> <p> 電容式接近傳感器是一個以電極為檢測端的經(jīng)電電容接近開關(guān)，它由高頻振蕩電路、檢波電路、放大電路、整形電路及輸出電路組成。 </p> <p> 平時檢測電極與大地之間存在一定的電容量，它成為振蕩電路的一個組成部分。當(dāng)被檢測物體接近檢測電極時，由于檢測電極加有電壓，檢測電極就會受到靜電感應(yīng)而產(chǎn)生極化現(xiàn)象，被測物體越靠近檢測電極，檢測電極上的感應(yīng)電荷就越多。由于檢測電極上的靜電電容為，所以隨著電荷量的增多，使檢測電極電容隨之增大。由于振蕩電路的振蕩頻率與電容成反比，所以當(dāng)電容C增大時振蕩電路的振蕩減弱，甚至停止振蕩。 </p> <p> 電感式接近傳感器 </p> <p> 電感式接近傳感器由高頻振蕩電路、檢波電路、放大電路、整形電路及輸出電路組成。檢測用敏感元件為檢測線圈，它是振蕩電路的一個組成部分，振蕩電路的振蕩頻率為。當(dāng)檢測線圈通以交流電時，在檢測線圈的周圍就產(chǎn)生一個交變的磁場，當(dāng)金屬物體接近檢測線圈時，金屬物體就會產(chǎn)生電渦流而吸收磁場能量，使檢測線圈的電感L發(fā)生變化，從而使振蕩電路的振蕩頻率減小，以至停振。振蕩與停振這兩種狀態(tài)經(jīng)監(jiān)測電路轉(zhuǎn)換為開關(guān)信號輸出。
