Abstract
Device for detecting electro-magnetically the level of a material which is conductive, or made conductive, particularly molten glass. The device comprises an inductor () creating an alternating current in the material and surrounding the container () of the material, at least one magnetic field sensor () in the zone delimited by the inductor, this sensor comprising a pair of transductors making it possible to detect the partial differential, along the axis of the inductor, of the radial component of the field, means () of demodulating the signals provided by the sensor, demodulation occurring with a phase shift of approximately π/2 relative to the current supplying the inductor, and means () for processing the signals provided by the demodulation means and for providing a signal indicating that the sensor level has been reached by the material.
