• festo電容式接近傳感器

  festo電容式接近傳感器德國FESTO費(fèi)斯托電容式接近傳感器的原理festo電容式接近傳感器由高頻振蕩器和放大器等組成，由傳感器的檢測面與大地間構(gòu)成一個(gè)電容器，參與振蕩回路工作，起始處于振蕩狀態(tài)。當(dāng)物體接近傳感器檢測面對，回路的電容量發(fā)生變化，使高頻振蕩器振蕩。振蕩與停振這二種狀態(tài)轉(zhuǎn)換為電信號經(jīng)放大器轉(zhuǎn)化成二進(jìn)制的開關(guān)信號。電容式接近傳感器的原理所有金屬型傳感器基本上屬于高頻振蕩型。和普通型一樣，它也有一個(gè)振蕩電路，電路中因感應(yīng)電流在目標(biāo)物內(nèi)流動(dòng)引起的能量損失影響到振蕩頻率。目標(biāo)物接近傳感器時(shí)，不論目標(biāo)物金屬種類如何，振蕩頻率都會(huì)提高。傳感器檢測到這個(gè)變化并輸出檢測信號。電感式接近開關(guān)的基本工作原理電感式傳感器為信號發(fā)生器，它被用于在加工機(jī)械，機(jī)器人，生產(chǎn)線以及傳送帶系統(tǒng)中檢測和功能相關(guān)的動(dòng)作,并將檢測結(jié)果轉(zhuǎn)換成電信號。它是以非接觸的方式工作的。當(dāng)有金屬物體接近規(guī)定的感應(yīng)距離時(shí)，傳感器會(huì)發(fā)出一個(gè)電信號。電感式接近開關(guān)就是利用電渦流效應(yīng)制造的傳感器。（1）高頻振蕩型電感式接近開關(guān)：它以高頻振蕩器（LC振蕩器）中的電感線圈作為檢測元件，利用被測金屬物體接近電感線圈時(shí)產(chǎn)生的渦流效應(yīng)，引起振蕩器振幅或頻率的變化，由傳感器的信號調(diào)理電路將該變化轉(zhuǎn)換成開關(guān)量輸出，從而達(dá)到檢測的目的。（2）差動(dòng)線圈型電感式接近開關(guān)：它有兩個(gè)電感線圈，由其中一個(gè)電感線圈作為檢測線圈，另一個(gè)電感線圈作為比較線圈；由于被測金屬物體接近檢測線圈時(shí)會(huì)產(chǎn)生渦流效應(yīng)，從而引起檢測線圈中磁通的變化，檢測線圈的磁通與比較線圈的磁通進(jìn)行比較，然后利用比較后的磁通差，經(jīng)由傳感器的信號調(diào)理電路將該磁通差轉(zhuǎn)換成電的開關(guān)量輸出，從而達(dá)到檢測的目的。2.3.2電感式接近開關(guān)的分類（1）按工作電源的性質(zhì)進(jìn)行分類①流型：采用交流電源供電，用于交流控制回路。②流型：采用直流流電源供電，用于直流控制回路。（2）按接線方式進(jìn)行分類①二線制②三線制③四線制④五線制⑤六線制（3）按觸點(diǎn)的性質(zhì)分類①常開式②常閉式③常開與常閉混合式festo電容式接近傳感器按輸出邏輯分類①正邏輯型②負(fù)邏輯型③浮空邏輯型④混合型（5）按外形分類①螺紋型②圓柱型③長方體型④U型等（6）按防護(hù)方式分類①防水型②防爆型③耐高溫型④耐高壓型等2.3.3電感式接近開關(guān)的圖形符號接近開關(guān)通用符號如圖2.2所示，電感式接近開關(guān)如圖2.3所示。圖2.2接近開關(guān)通用符號圖2.3電感式接按開關(guān)圖形符號2.3.4電感式傳感器的特點(diǎn)-無機(jī)械磨損和撕扯動(dòng)作，因此使用壽命長；-不會(huì)因灰塵或觸點(diǎn)焊接在一起而出現(xiàn)故障；-無觸點(diǎn)反彈，因此無切換故障；-切換頻率高達(dá)3000Hz；-抗震；-安裝位置隨意；-黃色LED顯示切換狀態(tài)；-完全密閉，防護(hù)等級高。2.3.5電感式傳感器在自動(dòng)檢測中的應(yīng)用由于電感式傳感只能對金屬起作用，在自動(dòng)控制的應(yīng)用可以應(yīng)用在上例中進(jìn)行檢測白色的金屬或紅色的塑料，又可以應(yīng)用在流水生產(chǎn)線上檢測金屬工件是否到位。如圖2.4所示。當(dāng)工件到位后自動(dòng)輸出一個(gè)開關(guān)量信號。用以控制計(jì)數(shù)器計(jì)數(shù)或下一個(gè)加工步驟等。festo電容式接近傳感器[詳細(xì)]

  檢測距離的衰減性?；N為鐵質(zhì)，適合電感式傳感器檢測；而滑翹被測部分的尺寸略小于標(biāo)準(zhǔn)檢測物尺寸（標(biāo)準(zhǔn)被測物尺寸為3倍額定檢測距離，此應(yīng)用中，標(biāo)準(zhǔn)尺寸應(yīng)為120*120mm），這樣的話就會(huì)有一定的衰減?，F(xiàn)場抗干擾能力。這個(gè)是不容忽視的問題，普通電感式傳感器容易被電機(jī)或變頻器干擾，很多技術(shù)人員只對在此附近的應(yīng)用選擇相應(yīng)強(qiáng)抗電磁干擾的傳感器。但在汽車制造車間，廠房大，現(xiàn)場技術(shù)人員習(xí)慣使用對講機(jī)溝通，尤其是邊走邊用對講機(jī)對話時(shí)，會(huì)不經(jīng)意的靠近傳感器，導(dǎo)致短暫失效。安裝方面。隨著電感式傳感器的普及，傳感器不僅僅在電氣性能方面有所提升，其機(jī)械方面的設(shè)計(jì)也越來越人性化。要在Z*程度的實(shí)現(xiàn)人性化安裝。減少了多種近似產(chǎn)品的備貨和減少了安裝、維護(hù)的時(shí)間。穩(wěn)定運(yùn)行的保障。在車廠的使用中，要杜絕任何油污、塵污的侵蝕。另外，滑翹經(jīng)過軌道時(shí)，震動(dòng)是長期存在的，優(yōu)異的抗震動(dòng)性同樣是有著非常重要的作用。電感式傳感器具有以下特點(diǎn)：結(jié)構(gòu)簡單，傳感器無活動(dòng)電觸點(diǎn)，因此工作可靠壽命長。靈敏度和分辨力高，能測出0.01微米的位移變化。傳感器的輸出信號強(qiáng)，電壓靈敏度一般每毫米的位移可達(dá)數(shù)百毫伏的輸出。線性度和重復(fù)性都比較好，在一定位移范圍（幾十微米至數(shù)毫米）內(nèi)，傳感器非線性誤差可達(dá)0.05%~0.1%。同時(shí)，這種傳感器能實(shí)現(xiàn)信息的遠(yuǎn)距離傳輸、記錄、顯示和控制，它在工業(yè)自動(dòng)控制系統(tǒng)中廣泛被采用。但不足的是，它有頻率響應(yīng)較低，不宜快速動(dòng)態(tài)測控等缺點(diǎn)。電感式傳感器種類很多，常見的有自感式，互感式和渦流式三種。另外，更深入的講，在抗電磁干擾性、環(huán)境溫度、電壓擾動(dòng)以及安裝要求等方面，都存在著差異。安裝方面。隨著電感式傳感器的普及，傳感器不僅僅在電氣性能方面有所提升，其機(jī)械方面的設(shè)計(jì)也越來越人性化。要在Z*程度的實(shí)現(xiàn)人性化安裝。減少了多種近似產(chǎn)品的備貨和減少了安裝、維護(hù)的時(shí)間。穩(wěn)定運(yùn)行的保障。在車廠的使用中，要杜絕任何油污、塵污的侵蝕。另外，滑翹經(jīng)過軌道時(shí)，震動(dòng)是長期存在的，優(yōu)異的抗震動(dòng)性同樣是有著非常重要的作用。對于電感式傳感器，大家都不會(huì)陌生，是用于近距離定位金屬物體的通用方式。因?yàn)橹饕峭ㄟ^霍爾效應(yīng)來完成檢測，所以也稱為霍爾傳感器。其內(nèi)部結(jié)構(gòu)由兩部分構(gòu)成：前端由纏繞著發(fā)射、接收線圈的鐵芯構(gòu)成檢測部分；后端為電路部分，整體封裝在塑料或金屬外殼中。工作時(shí)，電磁鐵芯部分發(fā)生交變磁場，對靠近的金屬物體表面產(chǎn)生渦流效應(yīng)，從而削弱LC震蕩電路，放大電路部分分析電磁鐵芯接收線圈的微弱LC震蕩電路變化，并給予相應(yīng)的輸出。不同外形尺寸，其額定檢測距離一般至多到100mm。通常狀態(tài)下，各廠家對于其標(biāo)稱的檢測距離為在實(shí)驗(yàn)室條件下測得的額定檢測距離。實(shí)際應(yīng)用中，考慮到各方面的環(huán)境因素，其可靠檢測距離約為額定檢測距離的80%，但對于被測物是有一定要求的。由于應(yīng)用現(xiàn)場的被測物材料的導(dǎo)磁性和尺寸大小，一般情況下達(dá)不到標(biāo)準(zhǔn)被測物的要求，那么傳感器的檢測距離會(huì)進(jìn)一步的衰減，這也就是很多用戶感覺電感傳感器的檢測距離比廠家標(biāo)稱的小很多的原因。在這種非標(biāo)檢測的情況下，各廠家及其不同系列產(chǎn)品的差異較大。把被測的機(jī)械量，如位移、壓力等轉(zhuǎn)換為電容量變化的傳感器。它的敏感部分就是具有可變參數(shù)的電容器。其Z常用的形式是由兩個(gè)平行電極組成、極間以空氣為介質(zhì)的電容器。若忽略邊緣效應(yīng)，平板電容器的電容為εS/d，式中ε為極間介質(zhì)的介電常數(shù)，S為兩極板互相覆蓋的有效面積，d為兩電極之間的距離。d、s、ε三個(gè)參數(shù)中任一個(gè)的變化都將引起電容量變化，并可用于測量。因此電容式傳感器可分為極距變化型、面積變化型、介質(zhì)變化型三類。極距變化型一般用來測量微小的線位移或由于力、壓力、振動(dòng)等引起的極距變化(見電容式壓力傳感器)。面積變化型一般用于測量角位移或較大的線位移。介質(zhì)變化型常用于物位測量和各種介質(zhì)的溫度、密度、濕度的測定。70年代末以來，隨著集成電路技術(shù)的發(fā)展,出現(xiàn)了與微型測量儀表封裝在一起的電容式傳感器。這種新型的傳感器能使分布電容的影響大為減小，使其固有的缺點(diǎn)得到克服。電容式傳感器是一種用途極廣，很有發(fā)展?jié)摿Φ膫鞲衅?。典型的電容式傳感器由上下電極、絕緣體和襯底構(gòu)成。當(dāng)薄膜受壓力作用時(shí)，薄膜會(huì)發(fā)生一定的變形，因此，上下電極之間的距離發(fā)生一定的變化，從而使電容發(fā)生變化。但電容式壓力傳感器的電容與上下電極之間的距離的關(guān)系是非線性關(guān)系，因此，要用具有補(bǔ)償功能的測量電路對輸出電容進(jìn)行非線性補(bǔ)償。電容式傳感器也常常被人們稱為電容式物位計(jì)，電容式物位計(jì)的電容檢測元件是根據(jù)圓筒形電容器原理進(jìn)行工作的，電容器由兩個(gè)絕緣的同軸圓柱極板內(nèi)電極和外電極組成，在兩筒之間充以介電常數(shù)為e的電解質(zhì)時(shí)，兩圓筒間的電容量為C=2∏eL/lnD/d，式中L為兩筒相互重合部分的長度；D為外筒電極的直徑；d為內(nèi)筒電極的直徑；e為中間介質(zhì)的電介常數(shù)。在實(shí)際測量中D、d、e是基本不變的，故測得C即可知道液位的高低，這也是電容式傳感器具有使用方便，結(jié)構(gòu)簡單和靈敏度高，價(jià)格便宜等特點(diǎn)的原因之一。電容式傳感器與電阻式、電感式等傳感器相比有如下一些優(yōu)點(diǎn)：高阻抗、小功率,因而所需的輸入力很小，輸人能量也很低。電容式傳感器因帶電極板間靜電引力極小(約幾個(gè)10-5N)，因此所需輸入能量極小，所以特別適宜用來解決輸入能量低的測量問題，例如測量極低的壓力、力和很小的加速度、位移等，可以做得很靈敏,分辨力非常，能感受0.001μm甚至更小的位移。溫度穩(wěn)定性好。傳感器的電容值一般與電極材料無關(guān)，有利于選擇溫度系數(shù)低的材料，又因本身發(fā)熱極小，對穩(wěn)定性影響甚微。結(jié)構(gòu)簡單，適應(yīng)性強(qiáng)，待測體是導(dǎo)體或半導(dǎo)體均可,可在惡劣環(huán)境中工作。電容式傳感器結(jié)構(gòu)簡單,易于制造,可做得非常小巧，以實(shí)現(xiàn)某些特殊的測量;能工作在高低溫、強(qiáng)輻射及強(qiáng)磁場等惡劣的環(huán)境中，也能對帶有磁性的工件進(jìn)行測量。動(dòng)態(tài)響應(yīng)好。由于極板間的靜電引力很小，可動(dòng)部分做得很小很薄，因此其固有頻率很高，動(dòng)態(tài)響應(yīng)時(shí)間短，能在幾兆赫的頻率下工作，特別適合動(dòng)態(tài)測量，如測量振動(dòng)、瞬時(shí)壓力等。電容式傳感器的初始電容量很小,而傳感器的引線電纜電容(lm~2m導(dǎo)線可達(dá)800pF)、測量電路的雜散電容以及傳感器極板與其周圍導(dǎo)體構(gòu)成的電容等“寄生電容”卻較大，這一方面降低了傳感器的靈敏度;另一方面這些電容(如電纜電容)常常是隨機(jī)變化的，將使傳感器工作不穩(wěn)定，影響測量精度，其變化量甚至超過被測量引起的電容變化量，致使傳感器無法工作。因此對電纜的選擇、安裝、接法都要有要求。為減小電纜分布電容影響，可將電子線路的前級裝在離傳感器敏感部分很近的地方，或采用所謂“雙層屏蔽等電位傳輸技術(shù)”，工作頻率等于或接近諧振頻率時(shí)，諧振頻率破壞了電容的正常作用。因此，工作頻率應(yīng)該先擇低于諧振頻率?？梢詫?shí)現(xiàn)非接觸測量，具有平均效應(yīng)。例如非接觸測量回轉(zhuǎn)軸的振動(dòng)或偏心、小型滾珠軸承的徑向間隙等。當(dāng)采用非接觸測量時(shí),電容式傳感器具有平均效應(yīng)，可以減小工作表面粗糙等對測量的影響。[詳細(xì)]
