產品介紹
Dytran 3038A,背(bei)靠背(bei)校準(zhun)(zhun)(zhun)(zhun)加(jia)速計(ji)(ji)傳(chuan)感器(qi),設計(ji)(ji)用(yong)(yong)(yong)于(yu)安裝(zhuang)在微(wei)型動(dong)(dong)(dong)態振動(dong)(dong)(dong)篩上,用(yong)(yong)(yong)于(yu)校準(zhun)(zhun)(zhun)(zhun)安裝(zhuang)在其(qi)上安裝(zhuang)面上的(de)(de)其(qi)他(測(ce)試)加(jia)速計(ji)(ji)。它(ta)為(wei)確定未(wei)知加(jia)速度、速度和位移傳(chuan)感器(qi)的(de)(de)靈(ling)(ling)敏度和頻率(lv)響應(ying)特性提(ti)(ti)供(gong)了一種(zhong)方便的(de)(de)方法。已配備電(dian)(dian)(dian)動(dong)(dong)(dong)振動(dong)(dong)(dong)篩和控制系(xi)統的(de)(de)振動(dong)(dong)(dong)實(shi)驗室可以(yi)輕松地結合使(shi)用(yong)(yong)(yong)3027系(xi)列(lie),以(yi)完成內部NIST可追溯校準(zhun)(zhun)(zhun)(zhun)。3038A提(ti)(ti)供(gong)10 mV/g靈(ling)(ling)敏度,并通過10–32螺紋孔安裝(zhuang)到振動(dong)(dong)(dong)篩頭上。 與該系(xi)列(lie)中提(ti)(ti)供(gong)的(de)(de)雙端校準(zhun)(zhun)(zhun)(zhun)標準(zhun)(zhun)(zhun)(zhun)加(jia)速計(ji)(ji)進行背(bei)靠背(bei)比較,需要將測(ce)試加(jia)速計(ji)(ji)直接安裝(zhuang)到校準(zhun)(zhun)(zhun)(zhun)標準(zhun)(zhun)(zhun)(zhun)的(de)(de)頂部安裝(zhuang)面上,并使(shi)用(yong)(yong)(yong)電(dian)(dian)(dian)動(dong)(dong)(dong)振動(dong)(dong)(dong)篩系(xi)統以(yi)各(ge)種(zhong)頻率(lv)和振幅(fu)驅動(dong)(dong)(dong)耦合對。在每個測(ce)試頻率(lv)下(xia),設置(zhi)振幅(fu),并從測(ce)試加(jia)速計(ji)(ji)讀取(qu)相應(ying)的(de)(de)輸(shu)出。用(yong)(yong)(yong)戶需要提(ti)(ti)供(gong)電(dian)(dian)(dian)纜、電(dian)(dian)(dian)源裝(zhuang)置(zhi)和電(dian)(dian)(dian)動(dong)(dong)(dong)振動(dong)(dong)(dong)篩系(xi)統,形成一個完整的(de)(de)測(ce)量(liang)系(xi)統。3038A應(ying)用(yong)(yong)(yong)于(yu)低頻、低g水平測(ce)量(liang)。

產品工作原理
IEPE壓(ya)電(dian)(dian)式加速(su)度(du)傳感(gan)器內置壓(ya)電(dian)(dian)晶體,受到外界振動或者擠壓(ya)時壓(ya)電(dian)(dian)晶體會(hui)釋放電(dian)(dian)荷,傳感(gan)器內部處理(li)電(dian)(dian)路進而將電(dian)(dian)荷轉化為(wei)一個高(gao)電(dian)(dian)平(ping),低阻抗的電(dian)(dian)壓(ya)信(xin)號。
