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3303A1是一款微型三軸加速度傳感器/振動(dòng)傳感器，壓電式工作原理，專為狀態(tài)和使用監(jiān)控系統(tǒng)和主動(dòng)振動(dòng)控制系統(tǒng)而設(shè)計(jì)，自帶4針接口和3/8-28螺紋。
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.
