光電式接近傳感器中，發(fā)光二極管（或半導(dǎo)體激光管）的光束軸線和光電三極管的軸線在一個平面上，并成一定的夾角，兩軸線在傳感器前方交于一點。當(dāng)被檢測物體表面接近交點時，發(fā)光二極管的反射光被光電三極管接收，產(chǎn)生電信號。當(dāng)物體遠(yuǎn)離交點時，反射區(qū)不在光電三極管的視角內(nèi)，檢測電路沒有輸出。一般情況下，送給發(fā)光二極管的驅(qū)動電流并不是直流電流，而是一定頻率的交變電流，這樣，接收電路得到的也是同頻率的交變信號。如果對接收來的信號進行濾波，只允許同頻率的信號通過，可以有效地防止其他雜光的干擾，并可以提高發(fā)光二極管的發(fā)光強度。 </p> <p> 接近傳感器主要用于檢測物體的位移，在航空、航天技術(shù)以及工業(yè)生產(chǎn)中都有全方面的應(yīng)用。在日常生活中，如賓館、飯店、車庫的自動門、自動熱風(fēng)機上都有應(yīng)用。在安全防盜方面，如資料檔案、財會，廣東PCB荷載傳感器穩(wěn)定耐用、金融、博物館、金庫等重地，通常都裝有由各種接近開關(guān)組成的防盜裝置。在測量技術(shù)中，廣東PCB荷載傳感器穩(wěn)定耐用，長度、位置的測量；在控制技術(shù)中，如位移、速度、加速度的測量和控制，也都使用者大量的接近開關(guān)。

為了防止電渦流產(chǎn)生的磁場影響儀器的正常輸出安裝時傳感器頭部四周必須留有一定范圍的非導(dǎo)電介質(zhì)空間，如果在某一部位要同時安裝兩個以上的傳感器，就必須考慮是否會產(chǎn)生交叉干擾，兩個探頭之間一定要保持規(guī)定的距離，被測體表面積應(yīng)為探頭直徑3倍以上，當(dāng)無法滿足3倍的要求時，可以適當(dāng)減小，但這是以降低靈敏度為代價的，一般是探頭直徑等于被測體表面積時，靈敏度降低至70%，所以當(dāng)靈敏度要求不高時可適當(dāng)縮小測量表面積。 </p> <p> 對工作的溫度的要求 </p> <p> 一般進口渦流傳感器最高溫度不大于180℃，而國產(chǎn)的只能達到120℃，并且這些數(shù)據(jù)來源于生產(chǎn)廠家，據(jù)相關(guān)的各種資料分析，實際上，工作溫度超過70℃時，電渦流傳感器的靈敏度會明顯降低，甚至?xí)斐蓚鞲衅鞯膿p壞，在核電站工業(yè)、渦輪發(fā)動機制造、火箭發(fā)射、汽車發(fā)動機檢驗、冶金鋼鐵熔爐等領(lǐng)域必要耐高溫的電渦流傳感器耐受性必須很高，據(jù)悉英國真尚有集團電渦流傳感器設(shè)計工程師成功研發(fā)出了能夠耐受上千攝氏度的此類傳感器。電渦流傳感器的靈敏度受溫度的影響，在軸振測量中安裝使用電渦流傳感器應(yīng)盡量遠(yuǎn)離汽封，只有特制的耐高溫傳感器如高低溫電渦流傳感器才能用于安裝汽封附近。 </p> <p> <br /> </p><p> 壓力傳感器故障檢測： </p> <p> 檢查施工現(xiàn)場出現(xiàn)的故障，絕大多數(shù)是由于壓力傳感器使用和安裝方法不當(dāng)引起的，歸納起來有幾個方面。 </p> <p> 1、一次元件(孔板、遠(yuǎn)傳測量接頭等)堵塞或安裝形式不對，取壓點不合理。 </p> <p> 2、引壓管泄漏或堵塞，充液管里有殘存氣體或充氣管里有殘存液體，變送器過程法蘭中存有沉積物，形成測量死區(qū)。 </p> <p> 3、變送器接線不正確，電源電壓過高或過低，指示表頭與儀表接線端子連接處接觸不良。 </p> <p> 4、沒有嚴(yán)格按照技術(shù)要求安裝，安裝方式和現(xiàn)場環(huán)境不符合技術(shù)要求。 </p> <p> <br />

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)品都會進行特性試驗，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 </p>

稱重傳感器性能的好壞很大程度上取決于制造材料的選擇。稱重傳感器材料包括以下幾個部分：應(yīng)變片材料、彈性體材料、貼片黏合劑材料、密封膠材料、引線密封材料和引線材料。 </p> <p> 黏合劑材料 </p> <p> 貼片黏合劑是把應(yīng)變片和彈性體牢牢固定在一起，使它們產(chǎn)生的形變永遠(yuǎn)一致。由此可見，貼片黏合劑也是一個重要部件。21世紀(jì)初，使用叫多的貼片黏合劑是雙組分高分子環(huán)氧系列黏合劑。21世紀(jì)初，它的性能與它自身的純度、混合方式、儲存時間、固化方式、固化時間等關(guān)系很大，在使用之前按要仔細(xì)看它的詳細(xì)介紹。 </p> <p> 引線密封 </p> <p> 傳感器輸出引線如果不固定的話，會發(fā)生損壞或松動，導(dǎo)致信號不穩(wěn)定或沒有輸出。21世紀(jì)初傳感器輸出都采用連接器的方式，連接器的材質(zhì)和緊固力度也會給輸出帶來影響。較好采用連接器跟密封膠配合使用。內(nèi)部引線也需要固定，防止其到處移動。引線的質(zhì)量也很重要，其材質(zhì)性能從高到低的排列順序依次為鍍銀、銅線和鋁線。如果周圍高頻信號、無線電波干擾嚴(yán)重的話，還需采用屏蔽電纜；在腐蝕性環(huán)境和易燃易爆場合則需要采用防腐防阻燃和防爆電纜，外加套管進行保護。
