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3053B是一款微型三轴加速度传感器/振动传感器，压电式工作原理，灵敏度10mV/g，自带4针接口和黏贴安装设计。
The Dytran 3053B is a rugged, low profile miniature triaxial IEPE accelerometer with a vertical height of 0.35 inches (8.9 millimeters) and an overall weight of 6.2 grams.
Offered with a 10 mV/g sensitivity, the sensor incorporates quartz shear sensing elements, packaged in a lightweight titanium housing, with an industry standard 4-pin radial connector and adhesive mounting capabilities. Units are hermetically sealed for reliable operation in high humidity and dirty environments and also case isolated to avoid EMI/ground loop interference.
