加速度技術(shù)指標(biāo)： </p> <p> 傳感器主要工作特性分為有效響應(yīng)與亂真響應(yīng)兩類。 </p> <p> ●有效響應(yīng) effective response </p> <p> 在傳感器靈敏軸方向上，由輸入的機(jī)械振動(dòng)或沖擊所引起的傳感器的響應(yīng)。這種響應(yīng)是正確使用傳感器進(jìn)行測(cè)量，取得可靠數(shù)據(jù)所期望的。 </p> <p> ●亂真響應(yīng) spurious response </p> <p> 在使用傳感器測(cè)量機(jī)械振動(dòng)或沖擊時(shí)，由同時(shí)存在的其他物理因素所引起的傳感器的響應(yīng)。這種響應(yīng)是干擾正確測(cè)量的，是不期望的。 </p> <p> 有效響應(yīng)主要有： </p> <p> 靈敏度；幅頻響應(yīng)和相頻響應(yīng)；非線性度。 </p> <p> 亂真響應(yīng)主要有： </p> <p> 溫度響應(yīng)；瞬變溫度靈敏度；橫向靈敏度；旋轉(zhuǎn)運(yùn)動(dòng)靈敏度；基座應(yīng)變靈敏度；磁靈敏度；安裝力矩靈敏度；對(duì)特殊環(huán)境的響應(yīng)。 </p> <p> ●靈敏度：（Sensitivity） </p> <p> 指定的輸出量與指定的輸入量之比。 </p> <p> ●參考靈敏度：（Reference Sensitivity） </p> <p> 在給定的參考頻率和參考幅值下傳感器的靈敏度值。 </p> <p> 傳感器靈敏度越高，測(cè)量系統(tǒng)的信噪比就越大，系統(tǒng)就不易受靜電干擾或電磁場(chǎng)的影響。對(duì)某種具體的加速度計(jì)設(shè)計(jì)型式來說，靈敏度越高，云南東電研傳感器單價(jià)多少，則傳感器越重，云南東電研傳感器單價(jià)多少，共振頻率也越低。因此選用多大靈敏度受其重量和頻率響應(yīng)的制約。 </p> <p> <br />

超聲波傳感器是將超聲波信號(hào)轉(zhuǎn)換成其他能量信號(hào)（通常是電信號(hào)）的傳感器。超聲波是振動(dòng)頻率高于20kHz的機(jī)械波。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(diǎn)。超聲波對(duì)液體、固體的穿透本領(lǐng)很大，尤其是在陽光不透明的固體中。超聲波碰到雜質(zhì)或分界面會(huì)產(chǎn)生明顯反射形成反射回波，碰到活動(dòng)物體能產(chǎn)生多普勒效應(yīng)。超聲波傳感器廣泛應(yīng)用在工業(yè)、**、生物醫(yī)學(xué)等方面。 </p> <p> 常用的超聲波傳感器由壓電晶片組成，既可以發(fā)射超聲波，也可以接收超聲波。小功率超聲探頭多作探測(cè)作用。它有許多不同的結(jié)構(gòu)，可分直探頭（縱波）、斜探頭（橫波）、表面波探頭（表面波）、蘭姆波探頭（蘭姆波）、雙探頭（一個(gè)探頭發(fā)射、一個(gè)探頭接收）等。天津施克Sick傳感器售后維修上海持承自動(dòng)化設(shè)備有限公司主營糾偏傳感器，如需選型樣本，隨時(shí)來電！</p><div

2：由于超聲波傳感器以空氣作為傳輸介質(zhì)，因此局部溫度不同時(shí)，分界處的反射和折射可能會(huì)導(dǎo)致誤動(dòng)作，風(fēng)吹時(shí)檢出距離也會(huì)發(fā)生變化。因此，不應(yīng)在強(qiáng)制通風(fēng)機(jī)之類的設(shè)備旁使用傳感器。 </p> <p> 3：噴氣嘴噴出的噴氣有多種頻率，因此會(huì)影響傳感器且不應(yīng)在傳感器附近使用。 </p> <p> 4：傳感器表面的水滴縮短了檢出距離。 </p> <p> 5：細(xì)粉末和棉紗之類的材料在吸收聲音時(shí)無法被檢出（反射型傳感器）。 </p> <p> 6：不能在真空區(qū)或防爆區(qū)使用傳感器。 </p> <p> 7：請(qǐng)勿在有蒸汽的區(qū)域使用傳感器；此區(qū)域的大氣不均勻。將會(huì)產(chǎn)生溫度梯度，從而導(dǎo)致測(cè)量錯(cuò)誤。 </p> <p> <br /> </p><p> 傳感器按作用形式分如下： </p> <p> 按作用形式可分為主動(dòng)型和被動(dòng)型傳感器。 </p> <p> 主動(dòng)型傳感器又有作用型和反作用型，此種傳感器對(duì)被測(cè)對(duì)象能發(fā)出一定探測(cè)信號(hào)，能檢測(cè)探測(cè)信號(hào)在被測(cè)對(duì)象中所產(chǎn)生的變化，或者由探測(cè)信號(hào)在被測(cè)對(duì)象中產(chǎn)生某種效應(yīng)而形成信號(hào)。檢測(cè)探測(cè)信號(hào)變化方式的稱為作用型，檢測(cè)產(chǎn)生響應(yīng)而形成信號(hào)方式的稱為反作用型。雷達(dá)與無線電頻率范圍探測(cè)器是作用型實(shí)例，而光聲效應(yīng)分析裝置與激光分析器是反作用型實(shí)例。 </p> <p> 被動(dòng)型傳感器只是接收被測(cè)對(duì)象本身產(chǎn)生的信號(hào)，如紅外輻射溫度計(jì)、紅外攝像裝置等。 </p> <p> 傳感器的特點(diǎn)包括：微型化、數(shù)字化、智能化、多功能化、系統(tǒng)化、網(wǎng)絡(luò)化。它是實(shí)現(xiàn)自動(dòng)檢測(cè)和自動(dòng)控制的首要環(huán)節(jié)。傳感器的存在和發(fā)展，讓物體有了觸覺、味覺和嗅覺等感官，讓物體慢慢變得活了起來。通常根據(jù)其基本感知功能分為熱敏元件、光敏元件、氣敏元件、力敏元件、磁敏元件、濕敏元件、聲敏元件、放射線敏感元件、色敏元件和味敏元件等大類。

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(cè)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(cè)體振動(dòng)時(shí)支架也同時(shí)受激自振，資料表明，支架的自振頻率至少應(yīng)為機(jī)械旋轉(zhuǎn)速度的10倍，支架應(yīng)與被測(cè)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(shí)對(duì)系統(tǒng)特性沒有影響，但較好還是保證傳感器與被測(cè)面垂直。 </p> <p> 對(duì)初始間隙的要求 </p> <p> 各種型號(hào)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(shí)必須調(diào)整好合適的初始間隙，對(duì)每一套產(chǎn)品都會(huì)進(jìn)行特性試驗(yàn)，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(shí)候必須仔細(xì)研究配套的校驗(yàn)證書，認(rèn)真分析特性曲線，以確定傳感器是否滿足所要測(cè)量的間隙，一般傳感器直徑越大所測(cè)量間隙也越大

電阻應(yīng)變片是壓阻式應(yīng)變傳感器的主要組成部分之一。金屬電阻應(yīng)變片的工作原理是吸附在基體材料上應(yīng)變電阻隨機(jī)械形變而產(chǎn)生阻值變化的現(xiàn)象，俗稱為電阻應(yīng)變效應(yīng)。 </p> <p> 2、陶瓷壓力傳感器 </p> <p> 陶瓷壓力傳感器基于壓阻效應(yīng)，壓力直接作用在陶瓷膜片的前表面，使膜片產(chǎn)生微小的形變，厚膜電阻印刷在陶瓷膜片的背面，連接成一個(gè)惠斯通電橋，由于壓敏電阻的壓阻效應(yīng)，使電橋產(chǎn)生一個(gè)與壓力成正比的高度線性、與激勵(lì)電壓也成正比的電壓信號(hào)，標(biāo)準(zhǔn)的信號(hào)根據(jù)壓力量程的不同標(biāo)定為2.0/3.0/3.3mV/V等，可以和應(yīng)變式傳感器相兼容。 </p> <p> 3、擴(kuò)散硅壓力傳感器： </p> <p> 擴(kuò)散硅壓力傳感器工作原理也是基于壓阻效應(yīng)，利用壓阻效應(yīng)原理，被測(cè)介質(zhì)的壓力直接作用于傳感器的膜片上(不銹鋼或陶瓷)，使膜片產(chǎn)生與介質(zhì)壓力成正比的微位移，使傳感器的電阻值發(fā)生變化，利用電子線路檢測(cè)這一變化，并轉(zhuǎn)換輸出一個(gè)對(duì)應(yīng)于這一壓力的標(biāo)準(zhǔn)測(cè)量信號(hào)。 </p> <p> 4、壓電式壓力傳感器： </p> <p> 壓電效應(yīng)是壓電傳感器的主要工作原理，壓電傳感器不能用于靜態(tài)測(cè)量，因?yàn)榻?jīng)過外力作用后的電荷，只有在回路具有無限大的輸入阻抗時(shí)才得到保存。實(shí)際的情況不是這樣的，所以這決定了壓電傳感器只能夠測(cè)量動(dòng)態(tài)的應(yīng)力。 </p> <p> <br
