壓電壓力傳感器
基于壓(ya)電(dian)(dian)(dian)效應(Piezoelectri effect),利用(yong)電(dian)(dian)(dian)氣元件和其他機(ji)械把待測(ce)(ce)(ce)的(de)壓(ya)力轉換成為電(dian)(dian)(dian)量(liang)(liang),再進行相關測(ce)(ce)(ce)量(liang)(liang)工作(zuo)的(de)測(ce)(ce)(ce)量(liang)(liang)準確(que)儀(yi)器。壓(ya)電(dian)(dian)(dian)傳感器只可以應用(yong)在動態測(ce)(ce)(ce)量(liang)(liang)當中(zhong)。主要的(de)壓(ya)電(dian)(dian)(dian)材料是(shi):磷酸(suan)(suan)(suan)二氨胺、酒石(shi)酸(suan)(suan)(suan)鉀鈉(na)和石(shi)英。隨著技術的(de)發(fa)展,壓(ya)電(dian)(dian)(dian)效應也(ye)已(yi)經在多晶體上得到應用(yong)了。例如:壓(ya)電(dian)(dian)(dian)陶(tao)瓷(ci)(ci),昵(ni)鎂酸(suan)(suan)(suan)壓(ya)電(dian)(dian)(dian)陶(tao)瓷(ci)(ci)、昵(ni)酸(suan)(suan)(suan)鹽系壓(ya)電(dian)(dian)(dian)陶(tao)瓷(ci)(ci)和欽(qin)酸(suan)(suan)(suan)鋼壓(ya)電(dian)(dian)(dian)陶(tao)瓷(ci)(ci)等(deng)等(deng)都包(bao)括在內。
以壓(ya)電(dian)(dian)(dian)效(xiao)應(ying)為工(gong)作(zuo)原理的(de)(de)(de)傳(chuan)感(gan)器(qi)是(shi)機電(dian)(dian)(dian)轉換(huan)式(shi)和自(zi)發電(dian)(dian)(dian)式(shi)傳(chuan)感(gan)器(qi)。它的(de)(de)(de)敏感(gan)元件(jian)是(shi)用(yong)(yong)壓(ya)電(dian)(dian)(dian)材料(liao)(liao)制作(zuo)而成(cheng)的(de)(de)(de)。當壓(ya)電(dian)(dian)(dian)材料(liao)(liao)受到(dao)外力(li)作(zuo)用(yong)(yong)時(shi)表面會(hui)(hui)形(xing)成(cheng)電(dian)(dian)(dian)荷(he),電(dian)(dian)(dian)荷(he)通過電(dian)(dian)(dian)荷(he)放(fang)大(da)器(qi)、測(ce)量電(dian)(dian)(dian)路的(de)(de)(de)放(fang)大(da)以及(ji)變換(huan)阻(zu)抗以后,就(jiu)會(hui)(hui)被(bei)轉換(huan)成(cheng)為與所受外力(li)成(cheng)正比關系的(de)(de)(de)電(dian)(dian)(dian)量輸出。它用(yong)(yong)來測(ce)量力(li)以及(ji)可以轉換(huan)成(cheng)為力(li)的(de)(de)(de)非(fei)電(dian)(dian)(dian)物理量,例(li)如:加速(su)度和壓(ya)力(li)。
優點(dian)是:重量較(jiao)輕、工作可靠、結構簡單、信噪比高、靈敏度高以及信頻寬等(deng)
