Abstract

This paper describes the application of parametric three-dimensional (3D) finite element analysis techniques to accurately model the response of a new industrial electromagnetic sensing system. The study focuses on a magnetic transformation detector for hot steel strip, which is capable of measuring the austenite-to-ferrite phase transformation fraction of hot steel on-line as the material cools below the Curie temperature. This sensor presents several challenges with regard to modelling its response. First, small changes (∼0.3 mT) in the measured magnetic field must be detected against a much larger background value (∼160 mT). Second, the response of the sensor to variation in lift-off must be accurately determined so that changes in lift-off could be subsequently rejected using an appropriate compensation algorithm. Finally, an accurate model (error
