Induction Sensor for Controlling the Boundary Position and Electrical Conductivity of a Medium
摘要
Abstract
An induction sensor is created for controlling the boundary and electrical conductivity of a medium. A refined mathematical model of the device is developed. The dependence of the sensor’s signal on the distance to an electrically conductive cylinder and the position of its upper boundary are obtained experimentally and numerically. The behavior of the system’s response is studied using media with different electrical conductivity: copper, duralumin, stainless steel, and lead–tin cylinders with different mass fractions of copper powder.
