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3063B是一款IEPE三轴加速度传感器/振动传感器，压电式工作原理，内置静电屏蔽，防静电噪音干扰，灵敏度100mV/g，频率响应低，0.5Hz。
The Dytran 3063B is a highly rugged, triaxial IEPE accelerometer with built-in Faraday shield for electrostatic noise immunity, a sensitivity of 100 mV/g, built-in long discharge time constant and excellent low frequency response down to 0.5 Hz.
Design of the model 3063B incorporates ceramic shear crystal sensing elements, packaged in a stainless steel housing, with a 4-pin radial Bayonet style connector and 1/4-28 thru hole mount. Model 3063B is directly compatible with the Dytran model 6529 Immersion Proof sealing boot (sold separately). When used together, the sensor remains fully functional in an IP65 environment. Units are hermetically sealed for reliable operation in high humidity and dirty environments and case isolated to avoid EMI/ground loop interference.
