FAQ

QUESTION More»
  • 电容式传感器的基本原理有哪些?

    电容式传感器的感应面由两个同轴金属电极构成,该两个电极构成一个电容,串接在RC振荡回路内。电源接通时,RC振荡器不振荡,当一目标朝着传感器感应面靠近时,电容容量增加,振荡器开始振荡。通过后级电路的处理转换成开关信号,从而起到了检测有无物体存在的目的。电容式传感器能检测金属物体,也能检测非金属物体,对金属物体可以获得最大的动作距离,对非金属物体动作距离决定于材料的介电常数,材料的介电常数越大,可获得的动作距离越大。

  • 传感器的齐平与非齐平是什么意思?

    是指传感器的安装方法,齐平安装可以埋入金属内使用,非齐平则不可埋入金属内使用,但动作距离与齐平式相比,检测距离更长。 齐平式安装:传感器埋入金属性基座内,其有效感应工作表面与基座面齐平。 非齐平式安装:传感器不埋入金属性基座内,其有效感应工作表面必须与其座保持一定的尺寸。同一规格的接近传感器,非齐平式可获得最大感应距离。 齐平式安装的传感器的优点为:它们有更好的机械保护性能,与非齐平式安装的传感器相比较,抗干扰能力更强。 齐平式式安装的传感器与非齐平式式安装的传感器相比较,其作用距离大约是后者的69%。

  • 接近开关感应距离的误差范围是多少?

    传感器的感应距离和标准感应距离之间的误差,一般为±10%。
