高靈敏度三向低頻加速度計833系列-55℃低溫MEMS加速度傳感器：
特點(diǎn)： –55 to 125低溫加速度計，電容式原理，DC響應(yīng)，三軸加速度測量
V833系列產(chǎn)品是一款具有高靈敏度，可同步測量相互垂直的三軸向加速度和低頻振動的加速度傳感器，其特點(diǎn)是采用變?nèi)菔組EMS硅晶片為敏感元件，輸出信號與施加的加速度成比例輸出，輸出信號單向峰值為2.5V±2V。 此加速度傳感器為5.5~30V單端穩(wěn)壓電源供電，產(chǎn)品環(huán)境溫度穩(wěn)定性通過內(nèi)置電路的溫度補(bǔ)償實(shí)現(xiàn)。敏感元件和電子組件封裝在密封的陽極氧化鋁外殼中，連接方式為整線輸出，可定制客戶型號的連接器。信號地通過陽極氧化鋁外殼與測試對象隔離，833加速度傳感器可以用M3螺釘或粘合劑安裝。 V833系列加速度計廣泛應(yīng)用于低頻測量和緊湊封裝的研發(fā)或工業(yè)OEM應(yīng)用。
