Paper Abstract

A pulse induction type magnetic field sensor using an amorphous ribbon as sensing material is described. Its operation principle is based on the dependency of the magnetic properties of the ribbon on ambient magnetic field. Because of the minimal use of active elements simple structure actuate sensitivity (as high as 14V/mT) and good thermostability (as small as O. OO8pT/C) this kind of magnetic field sensor consisting of pulse current sources coils with an amorphous core and induction voltage detectors is successfully used in monitoring the core mandrel of a cold rolling mill for seamless steel pipes. 1
