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(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的3003B是一款高性能微型三軸加速度傳感器/振動(dòng)傳感器，壓電式工作原理，自帶放大器功能（IEPE）,可在高達(dá)175攝氏度工作環(huán)境下正常運(yùn)行，轉(zhuǎn)為井下鉆頭振動(dòng)監(jiān)測(cè)應(yīng)用而設(shè)計(jì)。
The Dytran 3003B is a high performance triaxial IEPE accelerometer capable of operating at temperatures up to +347°F (+175°C) and was designed for down-hole drill head vibration monitoring.
Sensors developed for down-hole vibration monitoring must be able to deliver accurate and reliable data, while simultaneously tolerating harsh conditions. Critical characteristics of these sensors include a miniature design, high temperature operation, and the ability to operate at low power levels. The Dytran 3003B is ideal for such applications, as it is packaged in a miniature titanium housing with a vertical height of just 0.37-inches (9.4-millimeters), is capable of reliable operation at temperatures up to +347°F (+175°C), and was specially designed to operate from +4.0 to +5.5 VDC compliance voltage.
The Dytran model 3003B triaxial accelerometer is offered with a sensitivity of 2 mV/g and 500g range, and is designed with adhesive mounting capabilities. Weighing just 6 grams, units incorporate four permanently attached 22-inch long lead wires.
