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3583BT是一款IEPE三轴加速度传感器/振动传感器,压电式工作原理,灵敏度500mV/g,重27g,频响低至0.25Hz,信噪比优异,集成陶瓷剪切感应元件。
The Dytran 3583BT is an IEPE triaxial accelerometer with a high sensitivity of 500 mV/g. Design of the model 3583BT incorporates miniature ceramic shear mode sensing elements, mounted to a single support and packaged in a welded titanium housing for a total weight of 27 grams.
Dytran 3583BT offers a low end frequency response of 0.25 Hz for excellent phase response at low frequencies. Units also have an electrical noise floor of 0.0002 g RMS, which allows for its excellent signal-to-noise ratio.
Units feature an industry standard 4-pin radial connector and stud mount and is epoxy sealed for reliable operation in dirty environments.
