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
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3303A1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，专为状态和使用监控系统和主动振动控制系统而设计，自带4针接口和3/8-28螺纹。
The Dytran 3303A is a triaxial IEPE piezoelectric accelerometer designed for use in Health and Usage Monitoring Systems (HUMS) as well as Active Vibration Control (AVC) applications typically found on commercial and military aircraft. Offered with a sensitivity of 10 mV/g, units incorporate a 4-pin "Mighty Mouse"™ connector with 3/8-28 thread.
Design of the Dytran model 3303A features quartz sensing elements, operating in shear mode and packaged in a compact stainless steel housing. The distinguishing feature of these accelerometers is their Dytran developed integral mounting bracket design, which facilitates improved sensor performance while eliminating costs associated with separate mounting brackets. They also offer a reduced mass, as compared to conventional sensors and mounting brackets. The Dytran model 3303A is hermetically sealed for reliable operation within high humidity and dirty environments, as well as case isolated to avoid EMI/ground loop interference.
