舊國標將應(yīng)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(fù)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(zhuǎn)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(zhuǎn)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(fù)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(yīng)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%，陜西PCB振動傳感器原裝原廠質(zhì)量，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(gòu)成計量總誤差的各個分量進行調(diào)整，陜西PCB振動傳感器原裝原廠質(zhì)量，從而獲得期望的準確

螺栓安裝，粘接安裝，磁性安裝和使用探針（“激振桿”）。每個方法都影響傳感器的高頻響應(yīng)，螺栓安裝提供了較寬的頻率響應(yīng)和較安全可靠的附件。所提到的所有其它方法都會降低傳感器的上限頻率范圍。把傳感器從密切接觸的測量點移開,插入可替代的安裝配件, 如粘接墊、磁座、或探針，會引進安裝共振。這個安裝共振頻率比傳感器的固有共振頻率低，降低了上限頻率范圍。傳感器離測量點越遠，安裝共振越低，可用的頻率范圍就越小。 </p> <p> 磁性安裝是一種快速、便攜式測量的簡便安裝方法，通常用于機械狀態(tài)監(jiān)測、預(yù)防性維護、點檢和振動趨勢應(yīng)用。粘接安裝通常用于臨時安裝或當測試對象表面不能進行螺栓安裝時。螺栓安裝技術(shù)要求接觸面光滑、平坦，推薦用于長久和/或安全的安裝。螺栓安裝被推薦用在高頻測試的場合。 </p> <p> <br /> </p> <p> <br />

加速度傳感器可以檢測交流信號以及物體的振動，人在走動的時候會產(chǎn)生一定規(guī)律性的振動，而加速度傳感器可以檢測振動的過零點，從而計算出人所走的步或跑步所走的步數(shù)，從而計算出人所移動的位移。并且利用一定的公式可以計算出卡路里的消耗。 </p> <p> 防手抖功能 </p> <p> 用加速度傳感器檢測手持設(shè)備的振動/晃動幅度，當振動/晃動幅度過大時鎖住照相快門，使所拍攝的圖像永遠是清晰的。 </p> <p> 閃信功能 </p> <p> 通過揮動手持設(shè)備實現(xiàn)在空中顯示文字，用戶可以自己編寫顯示的文字。這個閃信功能是利用人們的視覺殘留現(xiàn)象，用加速度傳感器檢測揮動的周期，實現(xiàn)所顯示文字的準確定位。 </p> <p> 硬盤保護 </p> <p> 利用加速度傳感器檢測自由落體狀態(tài)，從而對迷你硬盤實施必要的保護。大家知道，硬盤在讀取數(shù)據(jù)時，磁頭與碟片之間的間距很小，因此，外界的輕微振動就會對硬盤產(chǎn)生很壞的后果，使數(shù)據(jù)丟失。而利用加速度傳感器可以檢測自由落體狀態(tài)。當檢測到自由落體狀態(tài)時，讓磁頭復(fù)位，以減少硬盤的受損程度。 </p> <p> <br /> </p><p> 扭矩傳感器安裝注意事項： </p> <p> 1.安裝時，不能帶電操作，切莫直接敲打、碰撞傳感器。 </p> <p> 2.聯(lián)軸器的緊固螺栓應(yīng)擰緊，聯(lián)軸器的外面應(yīng)加防護罩，避免人身傷害。 </p> <p> 3.信號線輸出不得對地，對電源短路,輸出電流不大于10mA· 屏蔽電纜線的屏蔽層必須與 +15V電源的公共端（電源地）連接。 </p> <p> 4.日常的計量檢定校準工作中，對扭矩傳感器進行校準時，通常采用扭矩標準機來進行。由于扭矩傳感器的精度比較高，通常為 1 級及以上的扭矩傳感器，但在實際測量工作中，除了扭矩標準機自身的不確定度之外，影響扭矩傳感器測量結(jié)果的另外一個重要因素則是傳感器與扭矩標準機之間的連接質(zhì)量，特別是對高精度扭矩傳感器的校準中在不考慮扭矩標準機自身的不確定度時，連接質(zhì)量的優(yōu)劣將直接影響測量結(jié)果的準確度。在現(xiàn)有扭矩傳感器測量方法中，通常都是將傳感器串接入扭矩標準機中進行校準，故而在校準過程中不可避免要出現(xiàn)連接質(zhì)量可靠與否的問題。在以往為了保證連接安裝的穩(wěn)定性和牢固性，通常會采用剛性連接方式來安裝，此種方式在裝卸方面為檢測人員帶來諸多不便，加上加工零部件的加工精細度和配合間隙的存在，在實際測量過程中使得測量軸系之間的同軸度發(fā)生較大的變化，將嚴重影響測量結(jié)果的準確性。

壓電式力傳感器的頻率響應(yīng)由諧振頻率和阻尼因數(shù)構(gòu)成的一個二階系統(tǒng)，可以高于應(yīng)變式傳感器的10倍。壓電式力傳感器的高頻響應(yīng)由質(zhì)量塊機械特性和剛度決定的，低頻響應(yīng)則由電氣特性決定，相當于一個高通濾波器。壓電式傳感器可以測量準靜態(tài)到數(shù)千赫茲的量，而應(yīng)變式載荷傳感器為靜態(tài)（DC）到幾十赫茲，這使得它的應(yīng)用受到很多限制。 </p> <p> 高頻響應(yīng)是一個壓電式傳感器的機械特性，由上一部分（剛度）我們可以了解到，石英壓電式力傳感器比應(yīng)變式力傳感器具有更好的剛度，并且不需要敏感元件撓曲而產(chǎn)生輸出，因此，壓電式力傳感器能獲得更高的頻率響應(yīng)，其與剛度的平方成正比。 </p> <p> 頻率與質(zhì)量倒數(shù)的平方成正比，大部分應(yīng)變式傳感器技術(shù)規(guī)格中都列出了振鈴頻率，計算振鈴頻率的時候引入了1/2質(zhì)量塊的值，大部分載荷傳感器的安裝結(jié)構(gòu)，大約一半的質(zhì)量塊被固定住，傳感器的中心面相對于膜片，振鈴頻率就是該膜片的固有頻率。 </p> <p> <br />
