產(chǎn)品簡介
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)方向的場合下，只有應(yīng)用三軸加速度傳感器來檢測加速度信號(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(yùn)動(dòng)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(hào)。三維加速度傳感器具有體積小和重量輕特點(diǎn)，可以測量空間加速度，能夠全面準(zhǔn)確反映物體的運(yùn)動(dòng)性質(zhì)。
美國Dytran的3263A1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，重量4g，自帶4針徑向連接器和4-40螺紋安裝設(shè)計(jì)，同時(shí)集成3個(gè)陶瓷剪切感應(yīng)元件，高密封封裝，應(yīng)對超高濕度和多塵工作環(huán)境。
The Dytran 3263A1 is a miniature IEPE triaxial accelerometer with an overall weight of 5.6 grams.
Available with a sensitivity of 10 mV/g, design of the Dytran model 3263A1 features ceramic shear sensing elements, coupled with low noise electronics and packaged in a lightweight titanium housing. The accelerometers offer a broad frequency response with an industry standard 4-pin connector and 4-40 stud mounting. Units are hermetically sealed for reliable operation in harsh and dirty environments.
