Abstract

An expendable current profiler based on electromagnetic is introduced. Design of a current velocity sensor based on the law of electromagnetic induction is presented, after system composition and working process is introduced. The system provides a excitation signals circuit and a signal acquisition circuit with features such as high stability, high reliability, high sensitivity and high anti-interference. Comparative experiment between the system and another current profiler has been done, which confirms the accuracy of the system.
