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3433A1是一款低功率三轴加速度传感器/振动传感器，压电式工作原理，灵敏度：5 mV/g。
The Dytran 3433A1 is a low power, triaxial IEPE accelerometer with a 5 mV/g sensitivity and an overall weight of 14 grams.
Featuring a bias voltage from +1.5 to +3.0 VDC, the Dytran model 3433A1 was designed for low turn-on voltage applications where supply power is limited. Sensors developed for such applications must be able to deliver accurate and reliable data while simultaneously tolerating harsh conditions. Critical characteristics of these sensors include a low-profile design, broad operating temperature, and the ability to operate at low power levels. The Dytran model 3433A1 is ideal for such applications, as it is packaged in a lightweight titanium housing with a vertical height of 0.54-inches (13.7-millimeters).
The Dytran model 3433A1 is designed with 10-32 stud mounting capabilities and 4-pin 1/4-28 radial connector. Units are case isolated to avoid EMI/ground loop interference and are hermetically sealed for reliable operation in high humidity and dirty environments.
