产品简介
华体会网皇马的赞助商中有一种是三轴华体会网皇马的赞助商,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,只有应用三轴华体会网皇马的赞助商来检测加速度信号。由于三轴华体会网皇马的赞助商也是基于重力原理的,因此用三轴华体会网皇马的赞助商可以实现双轴正负90度或双轴0-360度的倾角,通过校正后期精度要高于双轴华体会网皇马的赞助商大于测量角度为60度的情况。三轴华体会网皇马的赞助商的好处就是在预先不知道物体运动方向的场合下,只有应用三维华体会网皇马的赞助商来检测加速度信号。三维华体会网皇马的赞助商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3243A是一款小型、防潮式三轴华体会网皇马的赞助商/振动传感器,自带2m防溅式电缆线。
The Dytran 3243A is a low profile, moisture resistant triaxial IEPE accelerometer with an overall height of 0.30 inches (7.6 millimeters) and weighing just 2.5 grams.
Featuring titanium construction, a 10 mV/g sensitivity and adhesive mounting, the model 3243A incorporates a 2-meter integral cable with a splash-proof boot at the point of sensor and cable connection. The hermetically sealed cable-to-accelerometer boot seal makes it possible for the sensor to be temporarily submerged during testing. Units are case isolated to avoid EMI/ground loop interference.
