Design of intelligent height control system based on eddy current sensor

In water jet cutting process, cutting quality and speed depend on the distance between cutting head and object. To solve the problem that it is difficult to realize precise control of water jet cutting technique in height track system, this paper designs a waterproofing eddy height-adjusting system based on eddy sensor in view of metal plate. This system realizes non-contact and intelligent height control. This paper also introduces mathematical modeling and simulation of eddy current sensor coil and explains design method and principle of detection circuit and crystal oscillating circuit. The actual production process verifies that this system satisfies performance indexes requirements and has high stability, and operation is safe and reliable.
