2.檢測精度高，湖南東電研傳感器技術指導，湖南東電研傳感器技術指導、穩(wěn)定性好、抗干擾性強。 </p> <p> 3.不需反復調(diào)零即可；連續(xù)測量正反扭矩。 </p> <p> 4.即可測量靜止扭矩，也可測量動態(tài)扭矩。 </p> <p> 5.體積小、重傳感器可脫離二次儀表使用，只要按插座針號提供

舊國標將應用對象和使用環(huán)境條件完全不同的“稱重”和“測力”兩種傳感器合二為一來考慮，對試驗和評價方法未給予區(qū)分。舊國標共有21項指標，均在常溫下進行試驗；并用非線性、滯后誤差、重復性誤差、蠕變、零點溫度附加誤差以及額定輸出溫度附加誤差6項指標中的比較大誤差，來確定稱重傳感器準確度等級，分別用0.02、0.03、0.05表示。 </p> <p> 衡器上使用的一種力傳感器。它能將作用在被測物體上的重力按一定比例轉換成可計量的輸出信號。 </p> <p> 考慮到不同使用地點的重力加速度和空氣浮力對轉換的影響，稱重傳感器的性能指標主要有線性誤差、滯后誤差、重復性誤差、蠕變、零點溫度特性和靈敏度溫度特性等。在各種衡器和質(zhì)量計量系統(tǒng)中，通常用綜合誤差帶來綜合控制傳感器準確度，并將綜合誤差帶與衡器誤差帶聯(lián)系起來，以便選用對應于某一準確度衡器的稱重傳感器。國際法制計量組織(OIML)規(guī)定，傳感器的誤差帶δ占衡器誤差帶Δ的70%，稱重傳感器的線性誤差、滯后誤差以及在規(guī)定溫度范圍內(nèi)由于溫度對靈敏度的影響所引起的誤差等的總和不能超過誤差帶δ。這就允許制造廠對構成計量總誤差的各個分量進行調(diào)整，從而獲得期望的準確

一般來說，越靈敏越好。越靈敏的傳感器對一定范圍內(nèi)的加速度變化更敏感，輸出電壓的變化也越大，這樣就比較容易測量，從而獲得更精確的測量值。較小加速度測量值也稱較小分辨率，考慮到后級放大電路噪聲問題，應盡量遠離較小可用值，以確保較好信噪比。較大測量極限要考慮加速度計自身的非線性影響和后續(xù)儀器的較大輸出電壓，估算方法：較大被測加速度×傳感器的電荷 / 電壓靈敏度。 </p> <p> 以上數(shù)值是否超過配套儀器的較大輸入電荷 / 電壓值，建議如已知被測加速度范圍可在傳感器指標中的“參考量程范圍”中選擇（兼顧頻響、重量），同時，在頻響、重量允許的情況下，靈敏度可考慮高些，以提高后續(xù)儀器輸入信號，提高信噪比。 </p> <p> 帶寬 </p> <p> 這里的帶寬實際上指的是刷新率。也就是說每秒鐘，傳感器會產(chǎn)生多少次讀數(shù)。對于一般只要測量傾角的應用，50HZ的帶寬應該足夠了，但是對于需要進行動態(tài)性能，比如振動，你會需要一個具有上百HZ帶寬的傳感器。 </p> <p> <br /> </p><p> 扭矩傳感器利與弊： </p> <p> 發(fā)展趨勢 </p> <p> 隨著自控系統(tǒng)的不斷完善和發(fā)展，對扭矩傳感器的精度、可靠性和響應速度提出了更高的要求。扭矩傳感器正呈現(xiàn)以下的發(fā)展趨勢： </p> <p> 1、測試系統(tǒng)向微型化數(shù)字化、智能化、虛擬化和網(wǎng)絡化方向發(fā)展； </p> <p> 2、從單功能向多功能發(fā)展，包括自補償、自修正、自適應、自診斷、遠程設定、狀態(tài)組合、信息存儲和記憶； </p> <p> 3、向著小型化、集成化方向發(fā)展。傳感器的檢測部分可以通過結構的合理設計和優(yōu)化來實現(xiàn)小型化，IC部分可以整合盡可能多的半導體部件、電阻到一個單獨的IC部件上，減少外部部件的數(shù)量； </p> <p> 4、由靜態(tài)測試向動態(tài)在線檢測方向發(fā)展； </p> <p> 不足之處 </p> <p> 遙測扭矩儀成功之處在于克服了電滑環(huán)的兩項缺陷，但也存在著三個不足之處， </p> <p> 1、易受使用現(xiàn)場電磁波的干擾； </p> <p> 2、由于是電池供電，所以只能短期使用； </p> <p> 3、由于在旋轉軸上附加了結構，易引起高轉速時的動平衡問題，在小量程及小直徑軸時更突出； </p> <p> 數(shù)字式扭矩傳感器吸取了上述各種方法的優(yōu)點并克服了其缺陷，在應變傳感器的基礎上設計了兩組旋轉變壓器，實現(xiàn)了能源及信號的非接觸傳遞。并做到了扭矩信號的傳遞與是否旋轉無關，與轉速大小無關，與旋轉方向無關。 </p> <p> <br />

壓電傳感器是動態(tài)測量設備。它們使用壓電傳感元件將機械現(xiàn)象變換或轉換為電信號。機械參數(shù)可以是力、壓力或振動。來自壓電元件的原始電信號是高阻抗電荷信號。該電荷信號通過外部電荷放大器或外部電壓放大器通常轉換為低阻抗電壓信號。電荷傳感器和放大器之間的電纜必須是***、低噪音的電纜，并且必須保持盡可能的短。 </p> <p> 內(nèi)部放大傳感器或ICP®傳感器采用微型放大器將高阻抗電荷信號轉換為低阻抗電壓信號。這些放大器在傳感器內(nèi)部，因此不需要低噪聲電纜或外部放大器。這些放大器設置增益，使輸出靈敏度標準化。 </p> <p> ICP®傳感器是兩線傳感器。它們由恒流直流電源供電。電源通常是18-30V，通過二極管來限制為2到20mA之間的恒流。典型的電池供電電源提供2mA恒定電流以延長電池壽命，而連續(xù)監(jiān)控系統(tǒng)提供更大電流以驅動更長的電纜。 </p> <p> <br /> </p> </p> <p> <br />

聲納傳感器和超聲波傳感器是經(jīng)常聽說的兩種探測裝置，很多人認為這兩種是一種傳感器，這兩種傳感器之間有什么區(qū)別呢？ </p> <p> 聲納傳感器直接探測和識別水中的物體和水底的輪廓，聲納傳感器發(fā)出一個聲波信號，當遇到物體后會反射回 </p> <p> 來，依據(jù)反射時間及波型去計算它的距離及位置。超聲波是一種振動頻率高于聲波的機械波，由換能晶片在電壓的激勵下發(fā)生振動產(chǎn)生的，它具有頻率高、波長短、繞射現(xiàn)象小，特別是方向性好、能夠成為射線而定向傳播等特點。聲納傳感器主要用于探測生物，比如用于探測水底有哪些生物，生物體形有多大等。經(jīng)常問你聽說的用于探測水怪的裝置就是聲納傳感器。 </p> <p> 超聲波對液體、固體的穿透本領很大，尤其是在不透明的固體中，它可穿透幾十米的深度。超聲波碰到雜質(zhì)或分界面會產(chǎn)生明顯反射形成反射成回波，碰到活動物體能產(chǎn)生多普勒效應。因此超聲波檢測廣泛應用在工業(yè)、**、生物醫(yī)學等方面。超聲波傳感器是利用超聲波的特性研制而成的傳感器。在工業(yè)方面，超聲波的典型應用是對金屬的無損探傷和超聲波測厚兩種。超聲波傳感器在醫(yī)學上的應用主要是診斷疾病，它已經(jīng)成為了臨床醫(yī)學中不可缺少的診斷方法。
