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3133A1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0.8g，自带4针1/4-28接头和黏贴安装设计，同时集成3英尺电缆线。
The Dytran 3133A1 is an ultra miniature IEPE triaxial accelerometer, weighing just 0.8 grams, and was designed to mount in spaces inaccessible to other types of accelerometers.
Available with a sensitivity of 10 mV/g, design of the Dytran model 3133A1 incorporates ceramic shear sensing elements with integral electronics, packaged in a robust, lightweight, welded titanium cube, with a 3-foot integral cable terminating to a 4-pin 1/4-28 connector and adhesive mounting capabilities. The cable is designed to mate with several different types of Dytran extension cables (sold separately).
Model 3133A1 is the world's smallest triaxial IEPE accelerometer with a 10 mV/g sensitivity.
