加速度传感器中有一种是三轴加速度传感器,同样的它是基于加速度的基本原理去实现工作的,加速度是个空间矢量,一方面,要准确了解物体的运动状态,必须测得其三个坐标轴上的分量;另一方面,在预先不知道物体运动方向的场合下,只有应用三轴加速度传感器来检测加速度信号。由于三轴加速度传感器也是基于重力原理的,因此用三轴加速度传感器可以实现双轴正负90度或双轴0-360度的倾角,通过校正后期精度要高于双轴加速度传感器大于测量角度为60度的情况。三轴加速度传感器的好处就是在预先不知道物体运动方向的场合下,只有应用三维加速度传感器来检测加速度信号。三维加速度传感器具有体积小和重量轻特点,可以测量空间加速度,能够全面准确反映物体的运动性质。
美国Dytran的3213M6是一款三轴加速度传感器/振动传感器,压电式工作原理,自带放大器功能(IEPE), 内建静电屏蔽,防噪防静电,自带4针M12接口和10-32的螺纹通孔,灵敏度100mV/g。
The Dytran 3213M6 is a low profile, triaxial IEPE piezoelectric accelerometer with built-in Faraday shield for electrostatic noise immunity, a sensitivity of 100 mV/g, a radial 4-pin Brad Harrison™ connector and a 10-32 thru hole mount. This unique configuration allows the sensor to be turned 360° prior to securing for ease of sensor installation.
Design of the model 3213M6 incorporates ceramic shear sensing elements, packaged in a robust aluminum housing. The series is hermetically sealed for reliable operation in high humidity and dirty environments and case isolated to avoid EMI/ground loop interference.
