加速度傳感器中有一種是三軸加速度傳感器，同樣的它是基于加速度的基本原理去實現工作的，加速度是個空間矢量，一方面，要準確了解物體的運動狀態，必須測得其三個坐標軸上的分量；另一方面，在預先不知道物體運動方向的場合下，只有應用三軸加速度傳感器來檢測加速度信號。由于三軸加速度傳感器也是基于重力原理的，因此用三軸加速度傳感器可以實現雙軸正負90度或雙軸0-360度的傾角，通過校正后期精度要高于雙軸加速度傳感器大于測量角度為60度的情況。三軸加速度傳感器的好處就是在預先不知道物體運動方向的場合下，只有應用三維加速度傳感器來檢測加速度信號。三維加速度傳感器具有體積小和重量輕特點，可以測量空間加速度，能夠全面準確反映物體的運動性質。
美國Dytran的3033B2是一款微型三軸加速度傳感器/振動傳感器，壓電式工作原理，重量僅11g，集成石英剪切感應元件，不銹鋼外殼材質，適應于小質量的振動監測。
The Dytran 3033B2 is a low profile triaxial IEPE accelerometer with a height of 0.31 inches (7.9 millimeters) and a total weight of 11 grams. Featuring quartz shear sensing elements packaged in a rugged stainless steel housing for improved frequency response, the model 3033B2 is ideal for low mass vibration monitoring.
The model 3033B2 utilizes a 3-foot integral cable and thru hole mounting capabilities. This centralized screw mounting configuration allows for the sensor to be turned 360° prior to securing for ease of sensor installation. If desired, the accelerometer may also be adhesively mounted to the test article.
