详细信息
加速度传感器中有一种是三轴加速度传感器，同样的它是基于加速度的基本原理去实现工作的，加速度是个空间矢量，一方面，要准确了解物体的运动状态，必须测得其三个坐标轴上的分量；另一方面，在预先不知道物体运动方向的场合下，只有应用三轴加速度传感器来检测加速度信号。由于三轴加速度传感器也是基于重力原理的，因此用三轴加速度传感器可以实现双轴正负90度或双轴0-360度的倾角，通过校正后期精度要高于双轴加速度传感器大于测量角度为60度的情况。三轴加速度传感器的好处就是在预先不知道物体运动方向的场合下，只有应用三维加速度传感器来检测加速度信号。三维加速度传感器具有体积小和重量轻特点，可以测量空间加速度，能够全面准确反映物体的运动性质。
美国Dytran的3143D是一款三轴IEPE加速度传感器/振动传感器，压电式工作原理，重量14g，自带4针径向连接器和6-32铰轴安装设计，同时集成3个陶瓷剪切模式感应元件，再配备钛合金外壳，应对超高湿度和多尘工作环境。
The Dytran 3143D is a miniature IEPE triaxial accelerometer with a vertical dimension of 0.34 inches (8.7 millimeters) and an overall weight of 14 grams. Available with a sensitivity of 10 mV/g, the Dytran model 3143D features three ceramic shear mode sensing elements packaged in a lightweight titanium housing.
Units utilize an industry standard radial 4-pin connector and thru hole 6-32 mounting screw. This ring style configuration allows the sensor to be turned 360° prior to securing for ease of installation. The Dytran model 3143D is hermetically sealed for reliable operation in high humidity and dirty environments, as well as case isolated to avoid EMI/ground loop interference.
