加速度计" width="534" height="458">

V810系列加速度计产品是专为测量加速度和低频振动设计的一款高灵敏度，低噪声的加速度传感器，其特点是采用变容式MEMS硅晶片为敏感元件，该敏感元件由一个很小的惯性质量块和一个挠性元件组成，该挠性元件位于两块极板之间。随着质量块在加速度作用下发生偏移，极板之间的电容也会发生变化；包含了交流激励和同步调制解调电路的加速度传感器内部信号调节器输出与加速度成正比的模拟电压信号，单端信号输出为2.5+/-2V; 产品由单端稳压电源提供8~36Vdc的供电，此产品内置温度补偿电路以获得稳定的温度响应特性。敏感元件和电路组件一起封装在小型轻巧外壳中，信号通过4针连接器输出，也可选一体线缆输出。带连接器的13M1-L线缆可以与传感器适配使用，信号地与测试对象隔离。810加速度传感器的安装可以通过粘合剂安装，也可用M3的公制螺丝安装。此产品广泛应用于需要精确测量和可靠封装的高速列车和高空飞行器测试。810系列产品广泛应用于需要精确测量的研发领域，同时产品封装非常适合在严苛的环境中使用。
