V810系列加速度計(jì)產(chǎn)品是專為測量加速度和低頻振動設(shè)計(jì)的一款高靈敏度，低噪聲的加速度傳感器，其特點(diǎn)是采用變?nèi)菔組EMS硅晶片為敏感元件，該敏感元件由一個很小的慣性質(zhì)量塊和一個撓性元件組成，該撓性元件位于兩塊極板之間。隨著質(zhì)量塊在加速度作用下發(fā)生偏移，極板之間的電容也會發(fā)生變化；包含了交流激勵和同步調(diào)制解調(diào)電路的加速度傳感器內(nèi)部信號調(diào)節(jié)器輸出與加速度成正比的模擬電壓信號，單端信號輸出為2.5+/-2V; 產(chǎn)品由單端穩(wěn)壓電源提供8~36Vdc的供電，此產(chǎn)品內(nèi)置溫度補(bǔ)償電路以獲得穩(wěn)定的溫度響應(yīng)特性。敏感元件和電路組件一起封裝在小型輕巧外殼中，信號通過4針連接器輸出，也可選一體線纜輸出。帶連接器的13M1-L線纜可以與傳感器適配使用，信號地與測試對象隔離。810加速度傳感器的安裝可以通過粘合劑安裝，也可用M3的公制螺絲安裝。此產(chǎn)品廣泛應(yīng)用于需要精確測量和可靠封裝的高速列車和高空飛行器測試。810系列產(chǎn)品廣泛應(yīng)用于需要精確測量的研發(fā)領(lǐng)域，同時產(chǎn)品封裝非常適合在嚴(yán)苛的環(huán)境中使用。
