如果加速度計(jì)的動(dòng)態(tài)質(zhì)量接近被測(cè)結(jié)構(gòu)物的動(dòng)態(tài)質(zhì)量，則會(huì)使振動(dòng)產(chǎn)生明顯的衰減。為此在諸如印刷電路板等又薄又輕的片狀構(gòu)件上測(cè)振時(shí)，為了得到準(zhǔn)確的數(shù)據(jù)必須采用重量輕的加速度計(jì)。如果被測(cè)物件呈現(xiàn)單自由度的響應(yīng)，則加速度計(jì)將使其共振頻率下降。 </p> <p> ●低頻響應(yīng) </p> <p> 使用壓電加速度計(jì)時(shí)，所用放大器低頻截止頻率多為2－5Hz，目的是以此來(lái)剔除許多壓電傳感器的熱釋電輸出。像隔離剪切式設(shè)計(jì)等隔離性好的設(shè)計(jì)型式可用在較低的頻率。壓阻式和變電容式加速度計(jì)則具有零頻響應(yīng)。 </p> <p> ●高頻響應(yīng) </p> <p> 加速度計(jì)的高頻響應(yīng)隨加速度計(jì)的機(jī)械性能和安裝方法而變。在安裝牢固時(shí)，大多數(shù)加速度計(jì)呈現(xiàn)無(wú)阻尼單自由度系統(tǒng)的頻響特性。以±5%為要求的話(huà)，其頻率響應(yīng)約平整到安裝共振頻率的五分之一。如果加適當(dāng)?shù)男拚驍?shù)，則可在更高的頻率上得到有用的數(shù)據(jù)。 </p> <p> ●溫度響應(yīng) </p> <p> 傳感器靈敏度隨溫度的變化，稱(chēng)為傳感器的溫度響應(yīng)。用 </p> <p> 常用壓電加速度計(jì)的溫度范圍為零度以下至+177°C 或 +260°C。某些特定型號(hào)，低溫可達(dá)零度，高溫可達(dá)760°C。很多種壓電加速度計(jì)設(shè)計(jì)型式在很寬的溫度范圍內(nèi)的溫度響應(yīng)很平。壓阻式、變電容式加速度計(jì)的典型溫度范圍為－18°C～+93°C。 </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(shuō)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(guò)程的變化。 </p> <p> 第三是線(xiàn)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(xiàn)性，但對(duì)于帶放大器的傳感器，還應(yīng)包括放大器的非線(xiàn)性。線(xiàn)性誤差曲線(xiàn)可以是凹形曲線(xiàn)，也可以是凸形曲線(xiàn)稱(chēng)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(lái)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(lái)降低誤差以滿(mǎn)足客戶(hù)的需要。 </p> <p> <br />
