详细信息
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3033B2是一款微型三轴加速度传感器/振动传感器，压电式工作原理，重量仅11g，集成石英剪切感应元件，不锈钢外壳材质，适应于小质量的振动监测。
The Dytran 3033B2 is a low profile triaxial IEPE accelerometer with a height of 0.31 inches (7.9 millimeters) and a total weight of 11 grams. Featuring quartz shear sensing elements packaged in a rugged stainless steel housing for improved frequency response, the model 3033B2 is ideal for low mass vibration monitoring.
The model 3033B2 utilizes a 3-foot integral cable and thru hole mounting capabilities. This centralized screw mounting configuration allows for the sensor to be turned 360° prior to securing for ease of sensor installation. If desired, the accelerometer may also be adhesively mounted to the test article.
