摘要
The present invention relates to a device for electromagnetically measuring, in real time, the percentage of austenite contained in a continuously running steel strip during an in-line process for manufacturing or transforming the latter, such that the magnetic field produced by the alternating current flowing through the emitter coil (1) produces, in the steel strip (5), induced currents that generate an induced magnetic field creating, in the receiver coil (2), an electromotive force that can be measured by the voltage measurement device (4), the amplitude of this electromotive force being dependent on the voltage applied to the emitter coil and on the nature of the steel in the strip (5). The device is characterized in that the first and second coils (1, 2) are arranged in parallel to one another with a set distance between them and, in use, on either side of the steel strip (5).
