The present invention proposes a measuring probe for a measurement of the material distribution inside the burden of a blast furnace. The measuring probe comprises a sensor with a transmitter coil and a receiver coil, which are protected by a protective shell against heat and abrasion. An alternating current is applied to the transmitter coil that emits a primary alternating magnetic field, which induces eddy currents in any electrically conductive material of the burden within the primary alternating magnetic field. The eddy currents generate a secondary alternating magnetic field and a receiver coil measures an electrical current, which is generated by the primary alternating magnetic field and the secondary alternating magnetic field. The measured electrical current is evaluated by a control and evaluation unit. The electrical current is indicative of the material distribution inside the burden of a blast furnace.
