位置和速度传感器

CEDRAT TECHNOLOGIES设计以下类型的近接位置传感器和速度传感器:

> SG传感器:应变片传感器进行结构变形的静态和动态测量:这是CEDRAT TECHNOLOGIES掌握的一个制造高精度位置传感器的解决方案。这些传感器用于测量我们的促动器和换能器的行程和振动。

> ECS传感器:涡流传感器利用由一个发射线圈提供的交流磁场来生成一个导电靶涡流。这些涡流可以通过各种方法进行电检测。

> LVDT传感器:这些传感器是线性差动变压器式传感器。通常它们由一个初级交流发射线圈和一对次级线圈组成的。由于初级线圈中铁芯的运动,它们能检测到磁阻的变化。

> 和MR传感器:霍尔效应或磁阻元件的电阻对所施加的磁场很敏感。这些传感器通常可用于制造磁线性或旋转编码器。

> VR传感器:可变磁阻传感器是由一个永磁铁和一个位于旋转齿轮前方的线圈组成的旋转速度传感器。它们提供正比于齿轮速度的交流信号,且无需电源供电。

> 电容式传感器:电容传感器使用电场代替磁场。它们利用两个电极间距离变化会产生电容的变化的效应。
