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工作的,加速度是個空間矢量,一方面,要準確了解物體的運動狀態,必須測得其三個坐標軸上的分量;另一方面,在預先不知道物體運動方向的場合下,只有應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雙軸正負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先不知道物體運動方向的場合下,只有應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,能夠全面準確反映物體的運動性質。
美國Dytran 3133A5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接頭和黏貼安裝設計,同時集成3英尺電纜線。
The Dytran model 3133A5 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 0.2 mV/g, design of the Dytran model 3133A5 incorporates quartz 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).
