Design and optimization of eddy current sensor for instrumented pipeline inspection gauge

摘要

Purpose - The purpose of this paper is to introduce an in line non-destructive inspection tool instrumented pipeline inspection gauge (IPIG) and the need for secondary sensors in it; and to design a proper configuration of eddy current based secondary sensor under given design constraints. Design/methodology/approach - The objective is achieved by designing a simple configuration, testing it experimentally and modifying it as per requirements. Findings - An optimized configuration is arrived at under given set of constraints. Originality/value - This paper presents a novel method to design an eddy current sensor, and especially addresses electromagnetic experts involved in coil based sensor designs.
