造纸工业出纸厚度测量-eddy

造纸工业中,流浆箱的出口边沿间隙决定纸张的厚度。造纸机械通常需要该间隙维持在4~6米。作为质量控制方法,需要持续测量上下边沿间隙变化。为此目的,将一个非接触电涡流传感器安装到一个边沿,并测量与之相对的另外一侧边沿。对侧边沿为钢制或铝制平板,作为传感器的被测物体。

In paper manufacture the lip gap at the headbox determines the thickness of the paper. Paper machines usually have a lip width between 4 and 6 metres. The measuring task is a constantly monitoring the gap between the upper and lower lip as a quality relevant variable. To manage this application a non-contact eddy current displacement sensor is fitted either to one or better to both sides. A steel or aluminium target plate fitted opposite the sensor serves as a measuring target.
