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(shí)現(xiàn)工作的，加速度是個(gè)空間矢量，一方面，要準(zhǔn)確了解物體的運(yùn)動(dòng)狀態(tài)，必須測(cè)得其三個(gè)坐標(biāo)軸上的分量；另一方面，在預(yù)先不知道物體運(yùn)動(dòng)方向的場(chǎng)合下，只有應(yīng)用三軸加速度傳感器來(lái)檢測(cè)加速度信號(hào)。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(shí)現(xiàn)雙軸正負(fù)90度或雙軸0-360度的傾角，通過(guò)校正后期精度要高于雙軸加速度傳感器大于測(cè)量角度為60度的情況。三軸加速度傳感器的好處就是在預(yù)先不知道物體運(yùn)動(dòng)方向的場(chǎng)合下，只有應(yīng)用三維加速度傳感器來(lái)檢測(cè)加速度信號(hào)。三維加速度傳感器具有體積小和重量輕特點(diǎn)，可以測(cè)量空間加速度，能夠全面準(zhǔn)確反映物體的運(yùn)動(dòng)性質(zhì)。
美國(guó)Dytran的3143M16是一款I(lǐng)EPE三軸加速度傳感器/振動(dòng)傳感器，坐墊型，壓電式工作原理，可安裝在車座上，集成10英尺電纜線。
The Dytran 5313A is a triaxial IEPE seat pad accelerometer, designed to be installed between the ride and vehicle seat in transportation-related applications. The model 5313A utilizes an integral 10-foot cable, terminating to (3) BNC plugs.
Construction of the Dytran model 5313A consists of a thin rubber cushion containing the model 3143M1 accelerometer. The model 3143M1 is mounted within the rubber housing, or may be used as a stand-alone accelerometer. The model 5313A seat pad accelerometer conforms to ISO 8041, which specifies the performance and tolerance limits for instruments designed to measure vibration values in human vibration response assessments.
