Abstract

The detection of bubbles in liquid metals is important for many technical applications. The opaqueness and the high temperature of liquid metals set high demands on the measurement system. The high electrical conductivity of the liquid metal can be exploited for contactless methods based on electromagnetic induction. We will present a measurement system which consists of one excitation coil and a pickup coil system on the opposite sides of the pipe. With this sensor we were able to detect bubbles in a sodium flow inside a stainless steel pipe and bubbles in a column filled with a liquid Gallium alloy.

摘要

检测液态金属中的气泡对许多技术应用都很重要。液态金属的不透明性和高温对测量系统提出了很高的要求。液态金属的高电导率可用于基于电磁感应的非接触式方法。我们将展示一种测量系统，它由一个励磁线圈和位于管道相对两侧的拾波线圈系统组成。使用这种传感器，我们能够检测不锈钢管道内钠流中的气泡以及充满液态镓合金的柱体中的气泡。
