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3133A1是一款三軸IEPE加速度傳感器/振動傳感器，壓電式工作原理，重量0.8g，自帶4針1/4-28接頭和黏貼安裝設(shè)計，同時集成3英尺電纜線。
The Dytran 3133A1 is an ultra miniature IEPE triaxial accelerometer, weighing just 0.8 grams, and was designed to mount in spaces inaccessible to other types of accelerometers.
Available with a sensitivity of 10 mV/g, design of the Dytran model 3133A1 incorporates ceramic shear sensing elements with integral electronics, packaged in a robust, lightweight, welded titanium cube, with a 3-foot integral cable terminating to a 4-pin 1/4-28 connector and adhesive mounting capabilities. The cable is designed to mate with several different types of Dytran extension cables (sold separately).
Model 3133A1 is the world's smallest triaxial IEPE accelerometer with a 10 mV/g sensitivity.
