<p> 對(duì)被測(cè)體的要求 </p> <p> 為了防止電渦流產(chǎn)生的磁場(chǎng)影響儀器的正常輸出安裝時(shí)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(shí)安裝兩個(gè)以上的傳感器，就必須考慮是否會(huì)產(chǎn)生交叉干擾，兩個(gè)探頭之間一定要保持規(guī)定的距離，被測(cè)體表面積應(yīng)為探頭直徑3倍以上，當(dāng)無(wú)法滿足3倍的要求時(shí)，可以適當(dāng)減小，但這是以降低靈敏度為代價(jià)的，一般是探頭直徑等于被測(cè)體表面積時(shí)，靈敏度降低至70%，所以當(dāng)靈敏度要求不高時(shí)可適當(dāng)縮小測(cè)量表面積。 </p> <p> 對(duì)工作的溫度的要求 </p> <p> 一般進(jìn)口渦流傳感器**高溫度不大于180℃，而國(guó)產(chǎn)的只能達(dá)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(shí)際上，工作溫度超過70℃時(shí)，電渦流傳感器的靈敏度會(huì)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(dòng)機(jī)制造、火箭發(fā)射、汽車發(fā)動(dòng)機(jī)檢驗(yàn)、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(guó)真尚有集團(tuán)電渦流傳感器設(shè)計(jì)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(cè)量中安裝使用電渦流傳感器應(yīng)盡量遠(yuǎn)離汽封，安徽勞易測(cè)Leuze傳感器辦事處，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，安徽勞易測(cè)Leuze傳感器辦事處。

具有熱釋電效應(yīng)的傳感器在瞬變溫度作用下將產(chǎn)生電輸出，該輸出的**大值與傳感器靈敏度和溫度改變量乘積的比值稱為瞬變溫度靈敏度。 </p> <p> 在溫度產(chǎn)生變化時(shí)，壓電元件會(huì)產(chǎn)生輸出信號(hào)，這稱之為熱釋電效應(yīng)。試件或氣流溫度的突變會(huì)引起這種溫度變化。大多數(shù)情況下這種效應(yīng)是很低頻的，只有信號(hào)適調(diào)儀的響應(yīng)在1赫以下，才能檢測(cè)到。如果信號(hào)適調(diào)儀有級(jí)間高通濾波器，則應(yīng)特別注意，熱釋電信號(hào)可能會(huì)使放大器飽和，使它短時(shí)間不工作。 </p> <p> 基座隔離式，剪切式，隔離剪切式設(shè)計(jì)的熱釋電效應(yīng)較小。壓阻式，變電容式的這種效應(yīng)是可以忽略的。 </p> <p> ●橫向靈敏度 </p> <p> 對(duì)于單向測(cè)量來說，要求加速度計(jì)不得對(duì)被測(cè)物體的橫向運(yùn)動(dòng)產(chǎn)生任何響應(yīng)是十分必要的。但加速度計(jì)不可能是完美無(wú)缺的，總是有一定的橫向靈敏度，它與橫向振動(dòng)的方向有關(guān)，其橫向靈敏度一般為軸向靈敏度的1～5%。恩德?？藢?duì)每個(gè)加速度計(jì)進(jìn)行橫向靈敏度校準(zhǔn)并給出其**大值。

傳感器的頻率測(cè)量范圍是指?jìng)鞲衅髟谝?guī)定的頻率響應(yīng)幅值誤差內(nèi)（±5%, ±10%, ±3dB）傳感器所能測(cè)量的頻率范圍。頻率范圍的高，低限分別稱為高，低頻截至頻率。截至頻率與誤差直接相關(guān)，所允許的誤差范圍大則其頻率范圍也就寬。作為一般原則，傳感器的高頻響應(yīng)取決于傳感器的機(jī)械特性，而低頻響應(yīng)則由傳感器和后繼電路的綜合電參數(shù)所決定。高頻截止頻率高的傳感器必然是體積小，重量輕，反之用于低頻測(cè)量的高靈敏度傳感器相對(duì)來說則一定體積大和重量重。 </p> <p> 內(nèi)部結(jié)構(gòu) </p> <p> 內(nèi)部結(jié)構(gòu)是指敏感材料晶體片感受振動(dòng)的方式及安裝形式，有壓縮和剪切兩大類，常見的有中心壓縮、平面剪切、環(huán)型剪切。中心壓縮頻響高于剪切型，剪切型的環(huán)境適應(yīng)性好于中心壓縮型。如配用積分型電荷放大器測(cè)量速度、位移時(shí)，較好選用剪切型產(chǎn)品，這樣所得信號(hào)波動(dòng)小，穩(wěn)定性好。 </p> <p> 取決于系統(tǒng)和加速度傳感器之間的接口。一般模擬輸出的電壓和加速度是成比例的。數(shù)字輸出一般使用脈寬調(diào)制（PWM）信號(hào)。 </p> <p> 內(nèi)置電路 </p> <p> 內(nèi)置的概念是將電荷/電壓轉(zhuǎn)換放大電路置于加速度計(jì)內(nèi)，成為具有電壓輸出功能的傳感元件。它可分雙電源(四線)及單電源(二線并帶偏置的稱ICP)兩種，下面所指內(nèi)裝電路專指ICP型。 </p> <p> <br /> </p><p> 壓力傳感器無(wú)法避免誤差有： </p> <p> 在選擇壓力傳感器的時(shí)候我們要考慮他的綜合精度，而壓力傳感器的精度受哪些方面的影響呢?下面我們注意說四個(gè)無(wú)法避免的誤差，這是傳感器的初始誤差。 </p> <p> 首先的偏移量誤差：由于壓力傳感器在整個(gè)壓力范圍內(nèi)垂直偏移保持恒定，因此變換器擴(kuò)散和激光調(diào)節(jié)修正的變化將產(chǎn)生偏移量誤差。 </p> <p> 其次是靈敏度誤差：產(chǎn)生誤差大小與壓力成正比。如果設(shè)備的靈敏度高于典型值，靈敏度誤差將是壓力的遞增函數(shù)。如果靈敏度低于典型值，那么靈敏度誤差將是壓力的遞減函數(shù)。該誤差的產(chǎn)生原因在于擴(kuò)散過程的變化。 </p> <p> 第三是線性誤差：這是一個(gè)對(duì)壓力傳感器初始誤差影響較小的因素，該誤差的產(chǎn)生原因在于硅片的物理非線性，但對(duì)于帶放大器的傳感器，還應(yīng)包括放大器的非線性。線性誤差曲線可以是凹形曲線，也可以是凸形曲線稱重傳感器。 </p> <p> 然后是滯后誤差：在大多數(shù)情形中，壓力傳感器的滯后誤差完全可以忽略不計(jì)，因?yàn)楣杵哂泻芨叩臋C(jī)械剛度。一般只需在壓力變化很大的情形中考慮滯后誤差。 </p> <p> 壓力傳感器的這個(gè)四個(gè)誤差是無(wú)法避免的，我們只能選擇高精度的生產(chǎn)設(shè)備，利用較近技術(shù)來降低這些誤差，還可以在出廠的時(shí)候進(jìn)行一定的誤差校準(zhǔn)，盡較大的可能來降低誤差以滿足客戶的需要。 </p> <p> <br />
