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)方向的場合下,只有應(yīng)用三軸加速度傳感器來檢測(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)方向的場合下,只有應(yīng)用三維加速度傳感器來檢測(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Dytran 3133A5是一款三軸IEPE加速度傳感器/振動(dòng)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(jì),同時(shí)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).
