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(xiàn)工作的，加速度是個空間矢量，一方面，要準(zhǔn)確了解物體的運動狀態(tài)，必須測得其三個坐標(biāo)軸上的分量；另一方面，在預(yù)先不知道物體運動方向的場合下，只有應(yīng)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(xiàn)雙軸正負(fù)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(yù)先不知道物體運動方向的場合下，只有應(yīng)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(zhǔn)確反映物體的運動性質(zhì)。
美國Dytran的3433A1是一款低功率三軸加速度傳感器/振動傳感器，壓電式工作原理，靈敏度：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.
